Gradle projects do not build correctly (the bin/ directory again)

#634 is the underlying issue, but that was closed by brushing it under the carpet (IMO it deserves to be fixed). The problem I have is actually worse - the classpath is incomplete because it doesn't contain resources created and/or copied into build/resources/main (for instance) by script targets in the build. It's easy to reproduce the problem - here's an example: https://github.com/scratches/vscode-gradle-nonsense (load it up in VSCode and try and run the tests from the codelens and they fail, even though the build succeeds from command line).

Empieza con el repositorio de reproducción enlazado y compara la ejecución de pruebas desde el VSCode codelens con la compilación exitosa desde la línea de comandos. Lee el issue #634 y el issue relacionado de vscode-java-debug, y luego rastrea cómo se representan en el classpath de pruebas de codelens los recursos creados o copiados en build/resources/main. Se considera completado cuando las pruebas reproducidas se ejecutan correctamente con esos recursos disponibles.
