Issues with Jargs.jar with Gradle

Does Gradle has any issues with reading the JARgs.jar? I used this jar for command line option parsing. It is working when I’m running my test in eclipse or through shell script. But when I’m running the test through the Gradle it looks like Gradle is not able to read the content from this file. So all my tests which require to use Jargs.jar is failing. Any help will be highly appreciated.

Please provide more details (exact error message, stack trace, reproducible example, etc.).
