ANT Build File Sample

用户从源代码开始编译时，如果没有安装eclipse等集成开发环境，可以使用Ant

<project name="HelloWorld" basedir="." default="main">

<property name="src.dir" value="src"/>
<property name="build.dir" value="build"/>
<property name="classes.dir" value="${build.dir}/classes"/>
<property name="jar.dir" value="${build.dir}/jar"/>
<property name="lib.dir" value="lib"/>
<property name="conf.dir" value="conf"/>

<property name="main-class" value="oata.HelloWorld"/>

<path id="classpath">
<fileset dir="${lib.dir}" includes="**/*.jar"/>
</path>

<target name="compile">
<mkdir dir="${classes.dir}"/>
<javac srcdir="${src.dir}" destdir="${classes.dir}" classpathref="classpath"/>
<copy todir="${classes.dir}">
<fileset dir="${conf.dir}"/>
</copy>
</target>

<target name="jar" depends="compile">
<mkdir dir="${jar.dir}"/>
<jar basedir="${classes.dir}" destfile="${jar.dir}/${ant.project.name}.jar">
<manifest>
<attribute name="Main-Class" value="${main-class}"/>
</manifest>
</jar>
</target>

<target name="clean">
<delete dir="${build.dir}"/>
</target>

<target name="run" depends="jar">
<java fork="true" classname="${main-class}">
<classpath>
<path refid="classpath"/>
<path location="${jar.dir}/${ant.project.name}.jar"/>
</classpath>
</java>
</target>

<target name="main" depends="clean,run"/>

</project>
