XML : Eclipse ANT Build.xml create JAR is showing corrupted file

I've been searching a lot about this and was not able to find any solution.

Basically I'm just trying to Create a jar from my project. Then use that for deployment.

Here's my code in build.xml

  <?xml version="1.0" ?>  <!-- Configuration of the Ant build system to generate a Jar file -->   <project name="TestMain" default="CreateJar">    <target name="CreateJar" description="Create Jar file">          <jar jarfile="SamCommon.jar" basedir="bin"/>    </target>  </project>    

This is working okay and the jar file is visible and can be opened in the root directory of the project.

But what I want is to create/generate the jar on a different location.

So I set this configuration but whenever it outputs the file in that destination it shows as corrupt file. Please advise
