Hello Baha,

You need a dependency to a jar containing the `np.com.bahadur.ExecTest` class.

According to: https://www.mojohaus.org/exec-maven-plugin/java-mojo.html the dependency should have scope ’runtime’ unless you set the ’classpathScope’ parameter to something else. 

Your pom has no dependencies at all.

Regards,
Tommy

Thank you for the Response, Tommy. I already had a classpathScope test as shown in baha_baniya / exec-maven-plugin-sample / source / pom.xml — Bitbucket.

Just figured out - I have to run class after test-compile phase in which phase test classes are generated. Bound exec:java  to  process-test-classes (previously it was  process-test-resources) and it worked.

Baha
