执行任务：[clean, :app:assembleDebug] 错误 - Android Studio 3

我是 android studio 的新人。我正在制作我的第一个应用程序，在之前的 2.3 版本中，我在制作应用程序时没有遇到问题或卡住。但是当我升级到新版本 3.0 时，当我尝试重建 apk 时，我遇到了问题。它停留在Executing tasks: [clean, :app:assembleDebug]。当我构建 apk、重建和清理时遇到同样的问题。

任何人都可以帮助解决这个问题吗？

我仍然无法解决这个问题。

将其放入系统变量中：

SLAVE_AAPT_TIMEOUT = 30 

然后重新启动 Windows，对我来说效果很好。
