Installation:
1. Set the ANT_HOME environment variable to point to this location.
2. Set the JAVA_HOME environment variable to point to the JDK location.
3. Add ANT_HOME/bin to your system's PATH environment variable.
Build file :
1. ${build.dir} means referenced a var :build.dir
2. specify diretory :
<property name="src.dir" value="src"/>
<!-- Temporary build directories -->
<property name="build.dir" value="build"/>
3. make dir on specified diretory :
<target name="prepare">
<mkdir dir="${build.lib}"/>
</target>
4. clean dir
<target name="clean" description="Remove all generated files.">
<delete dir="${build.dir}"/>
</target>
5. compile java files
<target name="compile" depends="prepare"
description="Compiles all source code.">
<javac srcdir="${src.dir}"
destdir="${build.classes}"/>
</target>
6. jar java files
<target name="jar" depends="compile"
description="Generates oreilly.jar in the 'dist' directory.">
<!-- Exclude unit tests from the final JAR file -->
<jar jarfile="${build.lib}/oreilly.jar"
basedir="${build.classes}"
excludes="**/*Test.class"/>
</target>
7. target can be invoked single : eg.
command line : ant jar
8. specify classpath and compile :
<path id="mypath">
<pathelement location="${java.home}/jre/lib/rt.jar"/>
</path>
<target name="all">
<javac srcdir=".">
<classpath refid="mypath"/>
</javac>
</target>
or
<path id="classpath">
<fileset dir="${lib.dir}">
<include name="**/*.jar"/>
</fileset>
</path>
9. copy files
<copy todir="${weblogic.dir}/${weblogic.server.home}/public_html/jsp">
<fileset dir="${src.www.dir}/jsp"/>
</copy>
10．Javadoc
<target name = “javadoc” depends=”compile,jar”>
<mkdir dir = “${doc.dir}/api”/>
<javadoc packagenames = “ myproj.*”
sourchpath = “${src.dir}”
destdir = “${doc.dir}/api”
author = “true”
version = “true”
use = “true”>
<classpath refid = “classpath”/>
</javadoc>
</target>
