    - #### forTasks

          BuildActionExecuter<T> forTasks​(String... tasks)

      Specifies the tasks to execute before executing the BuildAction. If not configured, null, or an empty array is passed, then no tasks will be executed.
      Parameters:
        `tasks` - The paths of the tasks to be executed. Relative paths are evaluated relative to the project for which this launcher was created. An empty list will run the project's default tasks.
      Returns:
        this

    - #### forTasks

          BuildActionExecuter<T> forTasks​(Iterable<String> tasks)

      Specifies the tasks to execute before executing the BuildAction. If not configured, null, or an empty array is passed, then no tasks will be executed.
      Parameters:
        `tasks` - The paths of the tasks to be executed. Relative paths are evaluated relative to the project for which this launcher was created. An empty list will run the project's default tasks.
      Returns:
        this

    - #### run

          T run()
          throws GradleConnectionException,
                IllegalStateException

      Runs the action, blocking until its result is available.
      Throws:
        `UnsupportedVersionException` - When the target Gradle version does not support build action execution.
        `UnsupportedOperationConfigurationException` - When the target Gradle version does not support some requested configuration option.
        `UnsupportedBuildArgumentException` - When there is a problem with build arguments provided by `ConfigurableLauncher.withArguments(String...)`.
        `BuildActionFailureException` - When the build action fails with an exception.
        `BuildCancelledException` - When the operation was cancelled before it completed successfully.
        `BuildException` - On some failure executing the Gradle build.
        `GradleConnectionException` - On some other failure using the connection.
        `IllegalStateException` - When the connection has been closed or is closing.
      Since:
        1.8

    - #### run

          void run​(ResultHandler<? super T> handler)
            throws IllegalStateException

      Starts executing the action, passing the result to the given handler when complete. This method returns immediately, and the result is later passed to the given handler's `ResultHandler.onComplete(Object)` method.

      If the operation fails, the handler's `ResultHandler.onFailure(GradleConnectionException)` method is called with the appropriate exception. See `run()` for a description of the various exceptions that the operation may fail with.

      Parameters:
        `handler` - The handler to supply the result to.
      Throws:
        `IllegalStateException` - When the connection has been closed or is closing.
