unit testing - test - Prueba de Gradle falla con error

gradle test

Question

Veo el siguiente en mi salida:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task '':test''.
> superClassName is empty!

Aprecio si alguien sabe como arreglarlo.

Ya he echado un vistazo a la http://issues.gradle.org/browse/GRADLE-1682 . Pero ninguna solución no ayudó.

Gist creado con más información: https://gist.github.com/emartynov/c88194c702b77f42a7c0

Aquí está stacktrace:

* Exception is:

Suena como http://issues.gradle.org/browse/GRADLE-1682 . Desactivar el escaneo de archivos de clase debería resolver el problema:

tasks.withType(Test) {
    scanForTestClasses = false
    include "**/*Test.class" // whatever Ant pattern matches your test class files
}
