Basic syntax for generating jar packages for common Java projects (using ant packaging)

Save the following as Build.xml:

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

<project name="Project name" basedir="." default="Jar">

     < Property &NBSP; name= " Src.dir " &NBSP;&NBSP;&NBSP;&NBSP;&NBSP; Span style= "font-size:13px;color:navy;font-family: ' Courier New '" >value= " src " />

     < Property &NBSP; name= " Jar.dir " &NBSP;&NBSP;&NBSP;&NBSP;&NBSP; Span style= "font-size:13px;color:navy;font-family: ' Courier New '" >value= " out " />

     < Property &NBSP; name= " Bin.dir " &NBSP;&NBSP;&NBSP;&NBSP;&NBSP; Span style= "font-size:13px;color:navy;font-family: ' Courier New '" >value= " bin " />

     < Property &NBSP; name= " Lib.dir " &NBSP;&NBSP;&NBSP;&NBSP;&NBSP; Span style= "font-size:13px;color:navy;font-family: ' Courier New '" >value= " Lib " />

<path id="classpath">

         <fileset   dir= " ${lib.dir} " &NBSP; includes= "**/*.jar" />

</path>

     <target &NBSP; name= " compile " >

<mkdir dir="${bin.dir}"/>

       <javac srcdir="${src.dir}" destdir="${bin.dir}" classpathref="Classpath"/>

</target>

     <target &NBSP; name= " clean "

        <delete &NBSP; file= " ${jar.dir}/${ Ant.project.name}.jar " />

        <delete &NBSP; dir= " ${bin.dir} " />

</target>

     <target &NBSP; name= " jar "   depends= " clean,compile " >

        <mkdir &NBSP; dir= " ${jar.dir} " />

        <jar &NBSP; destfile= " ${jar.dir}/${ Ant.project.name}.jar "   basedir= " ${bin.dir} " />

</target>

</project>

You only need to replace the project name, such as memcached, and the resulting jar is Memcached.jar.

The basic process of the jar target:

1) clean , clear the original bin and Span style= "font-family: ' Times New Roman '" >out directory, i.e. delete .class and .jar file

2) compile , using classpath Reference compile-time required jar , All files under src are compiled, generated by .class placed in bin in the directory.

3) Build the jar, Create a new out directory, and package all the files under the bin into the " project name . Jar"and place it in the Out directory.
