    • reportBuildException

      public static final <T> T reportBuildException(Callable<T> todo)

      A utility method for reliably reporting problems as BuildExceptions. It invokes the callable. If a Throwable occurs, it unwraps the causes until it finds the root BuildException and rethrows it. Any other Throwable is wrapped in a new BuildException which is then thrown.

      Effectively, the method thus either returns the requested result or a BuildException.

      Type Parameters:
      T - the generic type
      Parameters:
      todo - the todo
      Returns:
      the result

      public static BuildExceptionFormatter formatter()
      Return the default formatter for build exceptions.
