Adding log output to the checkForProhibitedDependencies method shows it's not even called. Oddly the error only happens with the testRuntimeClasspath. The testCompileClasspath works fine.

Comment From: wilkinsona

Adding log output to the checkForProhibitedDependencies method shows it's not even called

The method hasn't been called as the failure occurs while Gradle's preparing the task's inputs. Specifically, it's resolving the Configuration that's used as the task's classpath input. Only once this resolution has succeeded are things in the state that's required to call checkForProhibitedDependencies.

Oddly the error only happens with the testRuntimeClasspath. The testCompileClasspath works fine.

I believe this is because there aren't any non-platform dependencies in testCompileClasspath so there's nothing to resolve. testRuntimeClasspath has got org.junit.platform:junit-platform-launcher in it. The presence of that dependency means that there's some resolution to be done.
