Ant Tutorial


  • Build.xml is the backbone file for running ANT.
  • It has one project tag and at least one target tag.
  • Project Tag has three attributes
    • Name:- Project Name
    • Default:-Default target to be called
    • Basedir:- Basic Directory to do the needful.(More specifically it contains the absolute path.)
  • Example:
    <project name="My Project" default="compile" basedir=".">

  • Then the target tag
    • Name:- target name(Required)
    • Depends:-if dependent on other targets..(We can even use if statement like if there exist the property then the target is dependent on other target )
    • Description:- description.
  • Example:
    <target name="clean" description="Removing the all generated files.">
    <delete dir="${dir.build}"/>
    <delete dir="${dir.dest}"/>
    </target>
  • Then the property tag.
    • Name:-name of the property
    • Location:- It contains the property name.
    • Value:- we can place the property value between ${"name }
    • File:- The name of the property file.
  • Example:
    <property name="build" value="${build}"/>
    <property name="build" location="src"/>
    <property file="build.properties"/>
  • Sample: build.xml
<project name="My Project" default="compile" basedir=".">
<property name="build" value="${build}"/> 

 
<property name="src" location="src"/> 

 
<property file="build.properties"/> 

 
<project name="My Project" default="jar" basedir=".">
<property name="dir.src" value="src"/>
<property name="dir.build" value="build"/>
<property name="dir.dest" value="dest"/>
<target name="clean" description="Removing the all generated files.">
<delete dir="${dir.build}"/>
<delete dir="${dir.dest}"/>
</target>
<target name="prepare" depends="clean">
<mkdir dir="${dir.build}"/>
<mkdir dir="${dir.dest}"/>
<mkdir dir="${dir.src}"/>
</target>
<target name="compile" depends="prepare" description="Compilation of all source code.">
<javac srcdir="${dir.src}" destdir="${dir.build}"/>
</target>
<target name="jar" depends="compile" description="Generates Sample.jar file in the dest folder">
<jar jarfile="${dir.dest}/sample.jar" basedir="${dir.build}"/>
</target>
</project>
<target name="buildWar" depends="init" description="build a war file"/>

 
<target name="init" if="build"/>

 
<target name="init" unless="build"/>
