My First Ant Project

Create Java Project on Eclipse.

Add build.xml file.

<project name="FirstAntProject" 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="${dir.build}"/> </target> <target name="jar" depends="compile" description="Generates helloeddy.jar file in to the 'dest' directory."> <jar jarfile="${dir.dest}/helloeddy.jar" basedir="${dir.build}"/> </target> </project>

Add helloeddy class.

public class helloeddy {

public static void main(String args[]){

System.out.println("Hello Erdenebat Tsenddorj");
}
}
