Description

I have a real-world project which has a test-classified third-party dependency that is (out of necessity) compile-scoped rather then test-scoped (as the test-JAR unfortunately contains classes also useful outside of a testing context). This constellation causes the maven-surefire-plugin to fail with a NoClassDefFoundError, thus effectively preventing the project from being build:

Attached is a minimal Maven project (just the POM; whether there are test sources present doesn't change the outcome) that reproduces this problem.
