I am trying to use ant to be able to compile java files.
Installed ant in d:\ant
set ant_home and path.

Copied my source files to d:\ant\src (it contains packages)

Made build.xml file in ant folder

<?xml version="1.0" encoding="UTF-8"?>

<project name="M" default="release" basedir=".">
    <description>simple example build file

  <!-- set global properties for this build -->
  <property name="src" location="src"/>
  <property name="build" location="build"/>
  <property name="release"  location="release"/>

  <target name="init">
    <!-- Create the build directory structure used by compile -->
    <mkdir dir="${build}"/>

  <target name="compile" depends="init"
        description="compile the source " >
    <!-- Compile the java code from ${src} into ${build} -->
    <javac srcdir="${src}" destdir="${build}"/>

  <target name="release" depends="compile"
        description="generate the release" >
    <!-- Create the release directory -->
    <mkdir dir="${release}/lib"/>

    <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file -->
    <jar jarfile="${release}/lib/M.jar" basedir="${build}">
        <attribute name="Implementation-Title" value="com.p1.p2.main"/>
        <attribute name="Implementation-Vendor" value="Me Inc."/>
        <attribute name="Implementation-Version" value="1.0"/>
        <attribute name="Main-Class" value="com.p1.p2.main.App"/>

  <target name="clean"
        description="clean up" >
    <!-- Delete the ${build} and ${release} directory trees -->
    <delete dir="${build}"/>
    <delete dir="${release}"/>
