* What went wrong:
Execution failed for task ':core:compileJava'.

   > Could not resolve com.badlogicgames.gdx:gdx:1.11.0.
     Required by:

      > No matching variant of com.badlogicgames.gdx:gdx:1.11.0 was found. The consumer was configured to find an API of a library compatible with Java 6, preferably in the form of class files, and its dependencies declared extern
ally but:
          - Variant 'apiElements' capability com.badlogicgames.gdx:gdx:1.11.0 declares an API of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 7 and the consumer needed a component compatible with Java 6
          - Variant 'javadocElements' capability com.badlogicgames.gdx:gdx:1.11.0 declares a runtime of a component, and its dependencies declared externally:
              - Incompatible because this component declares documentation and the consumer needed a library
              - Other compatible attributes:
                  - Doesn't say anything about its target Java version (required compatibility with Java 6)
                  - Doesn't say anything about its elements (required them preferably in the form of class files)
          - Variant 'runtimeElements' capability com.badlogicgames.gdx:gdx:1.11.0 declares a runtime of a library, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares a component compatible with Java 7 and the consumer needed a component compatible with Java 6
