Returns:

The resulting .class file and the location in jar it is supposed to go to.

Throws:

Exception

Makes a jar out of some class files. Unfortunately it's very tedious.

Parameters:

filesInJar - Files created via compileTestClass.

Returns:

path to the resulting jar file.

Throws:

Exception
