Ant是一种基于Jav a的bui ld工具。
理论上来说,它有些类似于(Un ix)C中的make,但没有make的缺陷。
既然我们已经有了ma ke, g numak e, nm ake,jam以及其他的bu ild工具为什么还要要一种新的build工具呢?因为Ant的原作者在多种(硬件)平台上开发软件时,无法忍受这些工具的限制和不便。
类似于m ake的工具本质上是基于she ll(语言)的:他们计算依赖关系,然后执行命令(这些命令与你在命令行敲的命令没太大区别)。
这就意味着你可以很容易地通过使用OS特有的或编写新的(命令)程序扩展该工具;然而,这也意味着你将自己限制在了特定的OS,或特定的OS类型上,如Un ix。
Makef ile也很可恶。
任何使用过他们的人都碰到过可恶的t ab问题。
Ant的原作者经常这样问自己:“是否我的命令不执行只是因为在我的ta b前有一个空格?!!”。
类似于jam的工具很好地处理了这类问题,但是(用户)必须记住和使用一种新的格式。
Ant就不同了。
与基于shel l命令的扩展模式不同,Ant用Java的类来扩展。
(用户)不必编写sh ell命令,配置文件是基于XM L的,通过调用ta rget树,就可执行各种tas k。
每个t ask由实现了一个实现了特定T ask接口的对象来运行。
(如果你对Ant一点概念都没有的话,可能看不懂这一节,没有关系,后面会对t arget,task做详细的介绍。
你如果没有太多的时间甚至可以略过这一节,然后再回来浏览一下这里的介绍,那时你就会看懂了。
同样,如果你对m ake之类的工具不熟悉也没关系,下面的介绍根本不会用到mak e中的概念。

如:在cmd中运⾏ant.bat就可以执⾏程序,当然你选择要当前⽬录中存在⼀个build.xml(build.xml是默认的ant执⾏⽂件,当然你可以指定其他⽂件)etc⽬录中存放的都是⼀些xsl的输出模板,创建⼀个加强的导出各种任务的XML输出,使你的build⽂件摆脱过时的警告lib⽬录中存放的是ant程序需要依赖的jar包manual⽬录是ant程序的帮助⽂档3、在我的电脑 –> 右键属性 –> ⾼级系统配置 -> 环境变量中配置ant新建系统变量 ANT_HOME = D:\apache-ant-1.9.1这样环境变量就配置好了,但前提你需要配置jdk的环境变量。
用英语介绍蚂蚁5句式写一篇作文全文共6篇示例,供读者参考篇1Ants Are Awesome!Ants are some of the coolest little creatures on Earth. They're tiny but mighty insects that live in colonies with thousands or even millions of other ants. I think ants are awesome for so many reasons!First off, ants are incredibly strong for their size. An ant can lift 20 times its own body weight! That's like a small kid being able to pick up a car. How crazy is that? Ants use their powerful jaws and legs to carry food, build their nests, and move just about anything. I've seen ants working together to move a huge crumb that seemed like a boulder to them. Their teamwork is amazing.Ants also have a really fascinating way of living and working together. Each colony has queens who lay the eggs, workers who gather food and take care of the young, and soldier ants who protect the colony. It's like their own little city with everyone having an important job. The worker ants are my favoritebecause they never stop moving and get so much done in a day.I get tired just watching them scurry around!Another cool thing about ants is how they communicate with each other. They don't make sounds we can hear. Instead, they use chemical smells called pheromones to share messages and lead each other to food. It's like they have invisible trails that only they can sniff out. Some ants even do dance moves on the ground to tell their nestmates where food is. I'd love to be able to watch them up close through a microscope!One of the neatest things I've learned about ants is that there are over 12,000 different species all around the world. From fire ants to army ants to leafcutter ants, they come in many different colors and sizes. Some ants are teeny tiny, while others are quite large for an insect. A few can even squirt acid to fight off predators! With so many types, I'll never get bored studying these fascinating creatures.Everywhere you look outside, you're likely to see ants hard at work. Next time you spot some, I encourage you to observe them closely (but don't disturb their colony!). Watch how they coordinate, carry objects, and maybe even play hide-and-seek. Ants are living proof that great things can come in small packages. Even though they're little, they're capable of incrediblestrength, teamwork and determination. I have so much respect for these mighty mini workers!篇2Ants Are Amazing!Hello, my name is Emily and I'm going to tell you all about ants. They might be tiny but they are some of the coolest creatures on the planet!Did you know there are over 12,000 different species of ants? That's more than the number of kinds of birds and mammals combined! Ants live almost everywhere too - in deserts, rainforests, grasslands, even the Arctic. They are found on every continent except Antarctica. No matter where you go, you're likely to run into ants scurrying around.Here are 5 sentences that sum up why ants are so awesome:Ants are super strong and can lift many times their own body weight.They live in colonies with thousands or even millions of other ants.Ants have a sort of language where they communicate by smell and touch.Some ants have cool jobs like soldiers that protect the colony.Other ants are farmers that grow fungus or aphids for food!Now let me tell you more about each of those 5 sentences.Sentence 1: Ants are incredibly strong for their size. A colony of ants can even move huge objects like logs! Scientists measured the strength of a single ant and calculated that if an ant were the size of a human, it could bench press 600 pounds! Their strength comes from their thin, cylindrical body shape and their large mandible (jaw) muscles.Sentence 2: Most ants are social insects that live together in a colony or nest. The colony can have millions of ants all working together. They divide up the work with different ants having different roles or "jobs" to do. The queen ant is the only fertile female and her job is to lay eggs. The worker ants are females who gather food, dig tunnels, defend the nest and care for the larvae (baby ants). Male ants only have one role - to mate with the queen!Sentence 3: Ants communicate and coordinate their tasks through chemical scent trails. When an ant finds food, it leaves a trail of smelly pheromones for other ants to follow. Ants also useantenna to antenna contact and vibrations to share information and identify each other. It's like they have their own secret language!Sentence 4: Soldier ants protect the colony from intruders like other insects. They have very big powerful jaws to bite enemies. Some crazy ants even explode as a weapon, covering their foes in a sticky goo! Other ants act as security guards, carrying the larvae to safe chambers if the nest is disturbed.Sentence 5: Many ants are awesome farmers! Leafcutter ants actually grow fungus gardens to eat, carrying leaves into their underground nests. Other ants herd and protect aphids, which are little bugs that produce a sweet liquid called honeydew for the ants to drink. Pretty clever!There are so many other cool facts about ants I could share. Like how some ants can swim, while others go on incredible mass migrations when colony gets too big. Or how army ants colonies can have up to 20 million ants, moving like a pack of demonic predators and devouring every insect and small animal they find! Ants really are like little robots programmed for efficiency.In case you can't tell, I'm totally fascinated by ants. I even have an ant farm so I can watch a colony up close. There's still so much we don't know about how their highly organized societieswork. When I grow up, I want to be an entomologist, which is a scientist who studies insects like ants. I'll let you know if I discover anything new about them! Thanks for reading my essay. Ants may be tiny but they sure are mighty!篇3Ants are Amazing!Have you ever watched ants closely? They are such tiny creatures, but they are super fascinating! Let me tell you all about them in just 5 sentences.Ants are incredible little insects that live almost everywhere on Earth in organized colonies with many thousands of ants. 2) They are extremely hard workers who can lift and carry things much bigger and heavier than themselves by working together.3) Different ants have different jobs like looking after the young ones, building and repairing their nest, finding and collecting food, defending the colony, and even going to war against other ant colonies! 4) Some cool things about ants are that they can communicate by smell, they farm other insects for food, and they are one of the strongest creatures compared to their size. 5) Although ants are very small, by working as a team they canmove mountains (well, maybe not real mountains, but you know what I mean)!That's the 5 sentence introduction to ants. But there is just so much more to say about these amazing little creatures! Let me expand on each of those 5 sentences.Sentence 1: Ants truly are found almost everywhere on our planet in warm, cold, wet, and dry environments. The only places without ants are the Antarctic, Greenland, and some island nations. There are over 12,000 different species of ants identified so far. And get this - ants make up as much as 25% of the total animal biomass on Earth! That's crazy when you think about how tiny they are. Their colonies can be gigantic with millions and millions of worker ants all working hard together.Sentence 2: If you've ever tried to move a huge rock or piece of furniture, you know how difficult it can be even with adult human strength. But ants have been known to move objects over 50 times their body weight by pulling and pushing together as a team. It's their secret superpower! An individual ant is incredibly strong for its size. Scientists estimate that if an ant was the size of a human, it could bench press over 600 pounds! Their bodies are perfectly designed for powerful lifting, gripping, and climbing. I've even seen videos of ants constructing bridges and ramps bylinking their bodies together. Working as a team is the key to their incredible strength.Sentence 3: Ant colonies are so well-organized, it's like an underground city with different ant employees having specialized jobs. The queen ant is basically in charge and her only role is to lay eggs - up to 800,000 per day for some species! The worker ants are all females who handle every other task. Some become nurses to care for and feed the young larvae. Others are builders and repairmen who dig tunnels and construct elaborate nests. The hunter ants are tasked with searching for food sources and bringing back leaves, seeds, fruits and even insects or animal remains to feed the colony. Soldier ants are the security guards whose job is to protect the nest from danger like anteaters or attacks from other ant colonies they may go to war with. It's a full civil service workforce with everyone working for the greater good of their ant city!Sentence 4: Here are some other amazing ant abilities and behaviors. Many ant species release strong scents from special glands as a way to communicate and leave scent trails for other ants to follow. Some raise and "milk" other insects like aphids for their honeydew - it's like farming! Bulldog ants have one of the most painful insect stings and are even able to squirt venom in astream over 8 inches. The leafcutter ants in South America are incredible agriculturists who grow gardens of fungi to feed their colonies by carrying leaf pieces one by one. And the strongest muscle in the world compared to its size is found in the tiny ant! No wonder they can lift such big loads.Sentence 5: Although each individual ant seems insignificant and powerless, their overwhelming strengths come from cooperation, determination and sheer numbers when working as an ant unified colony. Like a wise philosopher ant once said, "The whole is greater than the sum of its parts." On their own ants are weak, but by combining their efforts they can achieve truly amazing feats together as one. That's an important lesson for humans too - when we cooperate and work hard as a team, there is little we cannot accomplish.So in summary, ants are unbelievably cool little creatures! From their crazy strength to their organized societies to their ability to communicate and even wage war, they pack a powerful punch for their size. Watching busy ants hard at work is a daily reminder about the importance of cooperation, persistence and grit. We could all learn a thing or two from our tiny ant friends with their remarkable teamwork abilities. Just don't squish them - ants rule!篇4Ants are Super Cool!Did you know that there are over 12,000 different kinds of ants all over the world? That's a ton of tiny creatures crawling around! Ants are some of the most amazing little bugs you'll ever see. I'm going to tell you all about them using just 5 sentences for each fact. Get ready to be ant-amazed!Sentence 1: Ants are insects that live in colonies. Sentence 2: They have three main body parts - a head, thorax, and abdomen. Sentence 3: Most ants can see, but only with their two compound eyes located on their heads. Sentence 4: They also have two antennae that help them smell and feel things around them. Sentence 5: Some ants even have stingers on their abdomens to protect themselves from predators.Sentence 1: Ants are social insects that live together in very organized groups called colonies. Sentence 2: Each colony has one queen ant whose job is to lay eggs. Sentence 3: There are also many sterile female worker ants that do chores like foraging for food, taking care of the young, building and defending the nest. Sentence 4: Some colonies even have soldier ants with huge powerful jaws to protect the colony. Sentence 5: The antsall work together as a super team to keep their colony surviving and thriving.Sentence 1: Ants are incredibly strong for how tiny they are. Sentence 2: They can lift 20 times their own body weight! Sentence 3: That would be like a kid picking up a huge horse. Sentence 4: Their strength comes from their strong jaw muscles and their skeletons made of a material called chitin. Sentence 5: With their mini-muscle power, ants can protect themselves, carry food, and even move their entire colony.Sentence 1: Most ants feed on sweet liquids like honeydew made by aphids. Sentence 2: But some species are hunters that eat other small bugs. Sentence 3: Ants locate their food using their excellent sense of smell. Sentence 4: When an ant finds a good food source, it leaves a trail of smelly pheromones for other ants to follow. Sentence 5: This helps the whole colony travel back and forth to stock up on lots of yummy food.Sentence 1: Ants communicate and cooperate really well using chemicals, sounds, and touch. Sentence 2: When an ant finds danger, it can release a pheromone that sends an alarm signal to the other ants. Sentence 3: Ants also use antenna movements and body rhythms to share information. Sentence 4: These different methods allow the colony to organizecomplicated behaviors like migrations. Sentence 5: It's just like the ants have their own secret language!Sentence 1: Some ants can go an entire month without food or water. Sentence 2: This is because their bodies are able to recycle the nutrients from decay within their colony's nest. Sentence 3: Pretty gross, but it allows the ants to survive difficult times when food is scarce. Sentence 4: Other ants collect and store food reserves in preparation for winter or dry seasons. Sentence 5: No matter what, ants always find clever ways to get the nourishment they need.Sentence 1: Ant colonies can be humongous, with millions of ants all working together. Sentence 2: The biggest ant colony ever found was over 6,000 kilometers wide! Sentence 3: That's longer than the entire country of Indonesia. Sentence 4: Colonies tend to be most successful in hot, wet climates near the equator. Sentence 5: In these ideal environments, ant cities can just keep expanding and expanding over many years.Sentence 1: Most ant species are helpful to humans, at least in small numbers. Sentence 2: They aerate and fertilize the soil, which is good for gardens and farms. Sentence 3: Ants also eat up pests that could damage crops. Sentence 4: On the other hand, when ants invade houses they can contaminate food andcause structural damage. Sentence 5: Overall though, ants play an important role in local ecosystems.I think ants are just about the coolest little creatures on the planet! From their underground cities to their mighty strengths to their groovy communication skills, ants are pretty spectacular. Next time you see an ant, don't step on it. Instead, watch it closely and try to appreciate how truly awesome these tiny conquerors are. The world of ants is a miniature world of endless wonders!篇5Ants Are Awesome!Hey there! My name is Jamie and I'm going to tell you all about ants today. Ants are these tiny little creatures that you see crawling around everywhere outside. At first you might not think they're that cool, but trust me, once you learn some stuff about them you'll be like "Whoa, ants are awesome!"The first cool thing about ants is how strong they are. Even though they're so small, ants can lift things that are like a billion times heavier than them! An ant can even lift a pencil which would be like a person lifting up a whole truck. That's because ants have cool muscle stuff that makes them super strong fortheir size. If humans were as strong as ants, we could run faster than cars and smash through walls!Another amazing ant fact is how hard they work. Ants are always super busy, collecting food, taking care of their ant babies (which are gross little worm things at first), and building their ant homes which are called colonies. Some ants are workers who dig the tunnels and gather food. Others are soldier ants who protect the colony and attack any bugs that mess with them. And then there's the queen ant who just has babies all day long! Can you imagine having that many kids? No thanks!But the coolest thing about ants has to be how they communicate. Ants talk to each other by leaving smells on the ground called pheromones. When an ant finds some yummy food, it leaves a trail of smells to tell the other ants "Hey dudes, I found some grub over here!" Then the other ants can follow that smelly trail right to the foods. It's like having your own personal GPS made out of stinky scents!Ants are also really smart and good at working together as a team. In their colonies, they have jobs and everyone knows what they're supposed to do. The worker ants will leave the colony and look for food, while the soldier ants guard the place. If a worker ant finds a big piece of food it can't carry alone, it will goget help from its ant buddies and they'll all work together to carry it home. Talk about awesome teamwork!So in five sentences: Ants are super strong for their size. Ants work really hard all the time. Ants communicate using stinky smells. Ants are smart team players. And ants are just all-around awesome little creatures! After learning those cool facts, I bet you'll never look at ants the same way again. Next time you see them marching around, you'll be like "You go ants, you awesome little buddies!" The end!篇6Ants Are Amazing!Hi there! My name is Emily and I'm going to tell you all about ants. They are so cool and interesting. I learned about them in science class and I can't wait to share what I know with you!What are ants? Ants are very small insects that live together in colonies. An ant colony can have millions of ants all working together. There are over 12,000 different types of ants found all around the world. They live almost everywhere except really cold places like the Arctic. Some ants are smaller than a grain of rice while others can be an inch long! But most are just a few millimeters in size.Ants are so much fun to watch. They are always busy, busy, busy! Ants are very strong for their size. Some ants can lift 20 times their own body weight. That would be like a kid my age lifting a car! Ants leave trails of smells called pheromones to lead each other to food. When one ant finds yummy crumbs, it leaves a trail for the rest to follow. Before you know it, there's a line of ants parading to the food.Ants live in underground nests that we call ant colonies. The ant colony is made up of one queen ant, lots of female worker ants, and some male ants. The male ants are quite lazy and their only job is to mate with the queen. The workers are all girls and they do everything else. They dig tunnels, find food, care for the babies, and protect the colony. Worker ants are so hardworking!The queen ant is very important. She is larger than the workers and her only jobs are to lay eggs and start new colonies. Queens can live over 20 years, much longer than workers who only live about a year. When a queen gets older, she leaves the nest along with some workers to start a whole new colony somewhere else. That's why you might sometimes see a swarm of flying ants - they are queens off to make new homes.I think ants are super cool little creatures. Here are five sentences that sum up the most important things about ants:Ants are small insects that live in colonies with many working together.There are over 12,000 kinds of ants found across the world.Ant colonies have one queen, lots of hardworking female workers, and some males.Worker ants dig tunnels, find food, care for babies, and protect the colony.Queen ants live a long time and start new colonies when they get older.Ants are truly amazing! They work so hard, can lift heavy things, and live in massive colonies. Next time you see ants scurrying around outside, remember all the cool things I told you about them. Ants are tiny but they are super strong and hardworking. Thanks for reading, bye!。
蚂蚁自我介绍一句话英文回答:Hi, my name is Ant. I am a hardworking and determined insect. I belong to a large community of ants, where we work together to achieve our goals. As an ant, I have many unique qualities that make me stand out.Firstly, ants are known for their strong work ethic. We are constantly busy, gathering food, building nests, and taking care of our colony. I am no exception to this. I always give my best effort in everything I do, whether it's foraging for food or carrying heavy loads back to the nest.Secondly, ants are highly organized and cooperative. We work in teams, communicating through pheromones and body language to coordinate our actions. For example, when we find a food source, we leave a trail of pheromones for other ants to follow. This helps us efficiently gather food and ensures that everyone in the colony is well-fed.Furthermore, ants are incredibly resilient and adaptable. We can overcome obstacles and find solutions to problems. For instance, if our path is blocked by a fallen leaf, we will work together to move it out of the way. We are also capable of finding alternative routes when faced with a difficult terrain or a sudden change in our environment.In addition, ants are known for their ability to plan ahead. We store food in our nests to prepare for times of scarcity. This forward-thinking mentality helps us survive and thrive in challenging conditions. I always try to think ahead and anticipate any potential challenges or obstacles that may come my way.Lastly, ants are known for their unity and teamwork. We understand that by working together, we can achieve more than we can as individuals. We support and rely on each other, just like a close-knit community. This sense of camaraderie and unity is what makes us ants so successful.中文回答:大家好,我叫蚂蚁。

ant指令详解2篇ant指令详解第一篇Ant(Another Neat Tool)是一款基于Java的构建工具,广泛用于自动化构建和部署Java应用程序。
它的诞生源于Apache软件基金会,可以帮助开发人员轻松地编译、打包和部署项目。
本文将详细介绍Ant指令的使用和功能。
Ant指令是Ant构建脚本中的命令行指令,用于定义构建流程、编译代码、打包文件等操作。
Ant采用XML格式的构建文件,将一组Ant指令按照特定的顺序组织起来,通过执行构建文件,可以自动完成一系列构建任务。
首先,让我们来了解一些常用的Ant指令。
首先是javac指令,用于将Java源代码编译成Java字节码文件。
示例代码如下:```xml<javac srcdir="./src" destdir="./bin"includeantruntime="false" />```上述指令将src目录下的Java源代码编译成字节码文件,并将生成的字节码文件存放在bin目录下。
接下来是jar指令,用于创建Java程序的可执行JAR文件。
示例代码如下:```xml<jar destfile="./dist/myapp.jar"><fileset dir="./bin" includes="**/*.class" /><fileset dir="./lib" includes="**/*.jar" /></jar>```上述指令将bin目录下的所有类文件和lib目录下的所有JAR文件打包成一个名为myapp.jar的JAR文件,并将其存放在dist目录下。
除了编译和打包,Ant还提供了许多其他有用的指令。
例如,copy指令可以用来复制文件或目录:```xml<copy file="./src/test.txt" todir="./dist" />```上述指令将src目录下的test.txt文件复制到dist目录下。
ant项目的基本结构-回复Ant项目的基本结构是指一个基于Apache Ant构建的项目的组织和布局。
Apache Ant是一种基于Java的构建工具,它使用XML文件来描述构建过程,可以管理项目的编译、测试、打包和部署等任务。
在本文中,我们将分步介绍Ant项目的基本结构以及每个部分的作用和功能。
一、项目根目录Ant项目的根目录是项目的主文件夹,通常包含项目的基本配置文件以及其他的子目录和文件。
可以将项目根目录命名为任何你喜欢的名称,但是建议使用小写字母和短划线来命名,以保持一致性和易读性。
二、build.xml文件在项目根目录下,最重要的文件是build.xml。
这个文件是Ant的主要配置文件,它用于描述项目的构建过程。
build.xml文件是一个XML文档,包含一系列的任务和目标,用于定义项目的编译、测试、打包和部署等操作。
build.xml文件通常定义了一些基本的构建任务,如编译源代码、运行单元测试、打包构建结果等。
你可以根据项目的需要修改和定制build.xml文件,添加或移除特定的任务和目标。
三、目录结构Ant项目的目录结构可以根据具体需求进行灵活调整,但是通常包含以下几个常见的目录:1. src目录:用于存放项目的源代码文件。
通常会按照不同的编程语言或模块进行划分,如Java源代码文件放在src/main/java目录下,测试代码文件放在src/test/java目录下。
2. lib目录:用于存放项目所依赖的外部Jar包文件。
这些Jar包可以在项目构建过程中被自动导入和编译。
3. bin目录:用于存放项目的编译输出目录,包括编译后的类文件、资源文件和其他打包结果。
通常会有一个与编码语言相关的子目录,如bin/java。
4. test目录:用于存放项目的测试文件,包括单元测试和集成测试。
通常会按照不同的测试类型和模块进行划分。
5. doc目录:用于存放项目的文档和说明文件。
这些文件可以包括项目的需求说明、设计文档、API文档、用户手册等。
Ant是什么?
Ant是一个构建工具,它可以帮助我们将项目开发过程中需要完成的各种步骤组织起来,通过一个简易的方式来构建整个项目。
Ant究竟能做什么呢?这取决于Ant的任务(Task),Ant有哪些任务,就能完成哪些工作!一些典型的任务是:编译java源代码、运行java程序、拷贝文件或目录、将编译完成的类打包等等。
当然,Ant是一个开放的架构,任何人,都可以按照自己的方式,添加自己的任务(Task),这需要遵守Ant的一些规范。
如何开始使用Ant?
1、确保你的机器已经安装了JDK,确保你的path环境变量中包含有java虚拟机的运行程
序,确保你的环境变量中有JA V A_HOME变量
2、下载ant并解压
3、设置ANT_HOME环境变量,指向ant解压根目录
4、在path环境变量中,添加ANT_HOME\bin目录
5、打开控制台,运行:ant
6、如果能够运行ant(忽略这些异常:Buildfile: build.xml does not exist!),而不是出现诸如
命令无法解释的错误,那么你的ant就安装成功了
Ant 的基本概念
Ant的运行,靠的是一个构建脚本,默认的名称叫build.xml,如果你在任何目录下运行ant命令,Ant将自动查找当前目录下有没有build.xml文件,如果有这个文件,就读取这个文件,并运行其中的默认target。
解释一下以上话的意思:
构建脚本
Ant根据构建脚本的描述来执行任务!构建脚本是一个xml格式的文件。
最简单的构建脚本是:
<?xml version="1.0" encoding="GBK"?>
<project name="测试脚本"default="copyfile"basedir=".">
<target name="copyfile">
<copy file=”d:/a.txt” todir=”c:/temp” overwrite=”true”/> </target>
</project>
如果把以上内容放到一个build.xml文件中,然后运行ant命令,Ant将执行拷贝文件的任务!
从这个最简单的构建脚本中,我们可以知道脚本的基本编写方法:
1、脚本的根元素是:<project>
2、所有的任务,必须通过一个<target>标签包围,一个<target>标签,可以包含多个任务。
3、<copy>标签描述了一个任务,这些任务必须放到一个<target>标签的内部,Ant都可以使
用哪些任务呢?请参考Ant的相关文档
4、<project>中可以包含多个<target>,如果不指定运行哪个任务(即直接运行ant命令),
那么,将使用<project>标签中指定的default属性的target。
构建脚本的命名
默认命名是build.xml,如果你的构建脚本的名称是build.xml,那么你可以直接运行ant命令,如果是其它的名称,如:mybuild.xml,那么,你的命令行应该改为:ant –f mybuild.xml。
运行特定任务?
运行:ant copyfile,将运行的是被命名为copyfile的target。
Ant的路径模式?
再看下面的ant构建脚本:
<?xml version="1.0" encoding="GBK"?>
<project name="测试脚本"default="copyfile"basedir=".">
<target name="copyfile">
<copy todir=”c:/temp” overwrite=”true”>
<fileset dir=”d:”>
<include name=”*.txt”/>
</fileset>
<copy>
</target>
</project>
有没有注意到这个文件,跟第一个文件的变化?没错,<copy>任务的file属性变了,现在是*.txt,可能你已经意识到,这个的意思是拷贝d:盘下所有的以txt为扩展名的文件到c:/temp 目录中。
完全正确!但是,究竟包不包含子目录下的txt文件呢?这就需要我们了解ant中的路径模式。
Ant中的路径模式非常重要,很多地方都会用到,所以,我们首先来学习的就是ant的路径模式!
你可以查看ANT_HOME/docs/manual/dirtasks.html#patterns下的文档描述!里面有最详细的说明。
简单归纳一下:
*符号,代表0个或若干个字符。
?符号,代表一个字符。
**代表一颗目录树。
Ant任务
Ant 有很多内置的(即你安装完ant之后就可以直接使用的任务)任务,但是也可以添加自己定义的任务。
如果你编写了自己的任务,或者你要引入一些不是ant自带的任务时,我们需要使用<taskdef>标签来定义:
比如:
<path id="xdoclet.task.classpath">
<fileset dir="${xdoclet.home}/lib">
<include name="**/*.jar"/>
</fileset>
<fileset dir="${xdoclet.home}/plugins">
<include name="**/*.jar"/>
</fileset>
</path>
<taskdef
name="xdoclet"
classname="org.xdoclet.ant.XDocletTask"
classpathref="xdoclet.task.classpath"
/>
在这段文本里,包含了很多内容:
1、<path>元素,是用来定义一个路径的,通常是定义classpath,因为classpath可以包括众多的jar包,也可以包括众多的目录,所以可以使用<fileset>标签或<pathelement>等标签来定义这些路径。
2、这些标签总体上来说都是轻易便能够看懂的。
无需过多的解释。
那个<include>标签中的name属性,正是一个路径模式,表示包括本目录(即dir 属性定义的目录。
)下的所有子目录中的jar文件。
定义完任务之后,就可以来使用它了,如:
<target name="生成Hibernate配置文件">
<xdoclet>
<fileset dir="${src.dir}/com/oa/model">
<include name="**/*.java"/>
</fileset>
<component
classname="org.xdoclet.plugin.hibernate.HibernateConfigPlugin"
destdir="${src.dir}"
version="3.0"
hbm2ddlauto="update"
jdbcurl="jdbc:mysql://127.0.0.1/oa_200706"
jdbcdriver="com.mysql.jdbc.Driver"
jdbcusername="root"
jdbcpassword="mysql"
dialect="org.hibernate.dialect.MySQLDialect"
showsql="true"
/>
</xdoclet>
</target>
具体如何使用,请参考关于这个task的相关说明文档。
