“java.lang.ClassNotFoundException: runner.Driver” Failure(s)

We keep getting this error on test runs at the very end:

“java.lang.ClassNotFoundException: runner.Driver”

That error ends the whole job without giving any additional results. Oddly, the same configuration works for other branches in the same account.

I know it is just something small I am missing, or not looking at. Does anyone have any good ideas of places to start?

Thanks,

Derek C.
