当我在Android Studio中“运行”我的项目时，在“消息”窗口中，我得到：
Gradle:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':play01:compileDebug'.
> Compilation failed; see the compiler error output for details.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
它说> Compilation failed; see the compiler error output for details. 那么“编译器错误输出”在哪里？和/或我如何运行--stacktrace选项？
