Codenameone Build Server Fail

When trying to build my Android app to APK, the build server errors and fails to build. However, in the simulator the application works fine, and the class that errors I believe was created by the compiler (it is not one of which is inside the application)

Here is the error log: –

:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no 

previous execution, etc.).

* What went wrong:
Execution failed for task ':compileDebugJavaWithJavac'.
> Compilation failed; see the compiler error output for details.

You removed the destroy() callback method from your main class. The main class should include 4 methods that don’t throw exceptions:

public void init(Object) {}
public void start() {}
public void stop() {}
public void destroy() {}
