I have added the jcommander jar file and the class pathelementlocation also. But still it is not working. Guide me to reach out.

Answer Source

I got it. Actually in the file set tag I mentioned the default path

<fileset dir="${lib-dir}">

example: C:/Project/Jars

But in my project I didn't create the exact path as it was mentioned in file set dir

In project I kept the project structure like C:/Project/Jars/lib

Now I changed the library path in the project structure to C:/Project/Jars and it works now.
