This probably means there is an issue with either the supplied classpath or 
filters.
See http://pitest.org for more details.

I'm wondering why the filter is not correct. I've literally put everything I have on the CP and tried the targetClasses/testClasses with star * or specific class path.

Thanks!

Pitest mutates compiled bytecode, not source files.

You do not look to have included the compiled code on the classpath - only its dependencies.

It is strongly recommended to use one of the build integrations (maven, gradle, ant) rather than the command line tool as this is much less error prone.
