ANT使用举例

Ant 作为一个开源的make工具，他的好处就不多说了。我下面给出一个例子，说明如何使用ant来开发和部署java程序。

<project name="abcm" default="deply" basedir=".">

<property name="src.dir" value="src"/>

<property name="build.dir" value="D:\Tomcat 5.0\webapps\abcm\WEB-INF\classes"/>

<property name="lib.dir" value="lib"/>

<property name="Name" value="abcm"/>

<property name="version" value="1.0"/>

<property name="subversion" value="1.0"/>

<property name="clover.out.dir" value="cloverout"/>

<property name="javadoc" value="http://java.sun.com/j2se/1.3/docs/api"/>

<property name="javac.debug" value="on"/>

<property name="javac.optimize" value="off"/>

<path id="lib.class.path">

<fileset dir="${lib.dir}">

<include name="**/*.jar"/>

</fileset>

<pathelement path="${clover.jar}"/>

</path>

<patternset id="support.files">

<include name="**/*.dtd"/>

<include name="**/*.xml"/>

<include name="**/*.xslt"/>

<!-- exclude everything we don't want in the jar -->

<!--<exclude name="${build.dir}/**/*"/>

<exclude name="${doc.dir}/**/*"/>

<exclude name="classes/**/*"/>

<exclude name="build.xml"/>-->

<exclude name="**/*.properties"/>

<exclude name="**/*.ccf"/>

<exclude name="**/*.cfg.xml"/>

<exclude name="net/sf/hibernate/jca/hibernate-service.xml"/>

<exclude name="META-INF/ra.xml"/> <!-- don't include ra.xml -->

</patternset>

<patternset id="source.files">

<!-- include everything we want in the src directory

that we didn't want in the jar itself -->

<include name="**/*.java"/>

<include name="**/*.properties"/>

<include name="**/*.ccf"/>

<include name="META-INF/ra.xml"/>

</patternset>

<target name="deply" depends="compile" description="Initialize the build">

<echo message="Copy deply xml file"/>

<copy todir="${build.dir}">

<fileset dir=".">

<include name="*.xml"/>

<exclude name="build.xml"/>

<exclude name="buildabcm.xml"/>

</fileset>

</copy>

</target>

<target name="compile" depends="init" description="Compile the Java source code">

<available

classname="org.eclipse.core.launcher.Main"

property="build.compiler"

value="org.eclipse.jdt.core.JDTCompilerAdapter"

classpath="${java.class.path}"/>

<javac

srcdir="${src.dir}"

destdir="${build.dir}"

classpathref="lib.class.path"

debug="${javac.debug}"

optimize="${javac.optimize}"

nowarn="on">

</javac>

</target>

<target name="init" depends="splash" description="Initialize the build">

<tstamp>

<format property="subversion" pattern="yyyy-MM-dd hh:mm:ss"/>

</tstamp>

<echo message="Build ${Name}-${version} (${subversion})"/>

<mkdir dir="${build.dir}"/>

<copy todir="${build.dir}">

<fileset dir="${src.dir}">

<patternset refid="support.files"/>

</fileset>

<fileset dir=".">

<include name="readme.txt"/>

<include name="lgpl.txt"/>

</fileset>

</copy>

</target>

<target name="splash" description="Display the logo">

<property name="splash.dir" location="."/>

<splash imageurl="file:${splash.dir}/abcm_log.gif" showduration="0"/>

</target>

</project>

说明：

<property name="src.dir" value="src"/>

…..

Property标记用来声明一些全局的变量，比如编译路径、部署路径、项目信息等等。

1、 类路径定义

<path id="lib.class.path">

<fileset dir="${lib.dir}">

<include name="**/*.jar"/>

</fileset>

<pathelement path="${clover.jar}"/>

</path>

上面的描述说明了java编译的classpath是什么。

2、 资源路径定义

<patternset id="support.files">

<include name="**/*.dtd"/>

<include name="**/*.xml"/>

<include name="**/*.xslt"/>

<!-- exclude everything we don't want in the jar -->

<!--<exclude name="${build.dir}/**/*"/>

<exclude name="${doc.dir}/**/*"/>

<exclude name="classes/**/*"/>

<exclude name="build.xml"/>-->

<exclude name="**/*.properties"/>

<exclude name="**/*.ccf"/>

<exclude name="**/*.cfg.xml"/>

<exclude name="net/sf/hibernate/jca/hibernate-service.xml"/>

<exclude name="META-INF/ra.xml"/> <!-- don't include ra.xml -->

</patternset>

定义所有要打包的资源文件。

3、 部署

<target name="deply" depends="compile" description="Initialize the build">

<echo message="Copy deply xml file"/>

<copy todir="${build.dir}">

<fileset dir=".">

<include name="*.xml"/>

<exclude name="build.xml"/>

<exclude name="buildabcm.xml"/>

</fileset>

</copy>

</target>

上面的描述用来将hiberbate需要的配置文件复制到classes下。

4、 编译

<target name="compile" depends="init" description="Compile the Java source code">

<available

classname="org.eclipse.core.launcher.Main"

property="build.compiler"

value="org.eclipse.jdt.core.JDTCompilerAdapter"

classpath="${java.class.path}"/>

<javac

srcdir="${src.dir}"

destdir="${build.dir}"

classpathref="lib.class.path"

debug="${javac.debug}"

optimize="${javac.optimize}"

nowarn="on">

</javac>

</target>

上面的描述是用来编译java 文件的。其中available一段的描述会在编译的时候显示一个splah画面默认是一只蚂蚁。
