Tech: Building a Jar file with Apache Ant

If you want to easily create a Jar file after you clone the repository, it can be done with Apache Ant using the following build.xml file:

<?xml version="1.0"?>
<project name="JSON-java" default="dist" basedir=".">
   <property name="jar" value="JSON-java.jar"/>

   <target name="build">
      <javac srcdir="." destdir="." includes="*.java" deprecation="yes" includeantruntime="false">
         <compilerarg value="-Xlint:unchecked"/>
      </javac>
   </target>

   <target name="dist" depends="build">
      <jar destfile="${jar}">
         <fileset dir="." includes="**/*.class"/>
      </jar>
   </target>
</project>

After cloning, save the content above on a file called build.xml and just type:

$ ant 

And there you go, you have a new JSON-java.jar file (the name can be changed on the name property) with the correct package directory structure, like this:

$ jar tf JSON-java.jar
