升级AndroidStuido 4.2后 Gradle Tasks 不见了？

近期很多人询问升级 AndroidStudio 4.2 之后，Gradle窗口中看不到Tasks了

• 4.2之前
  

• 4.2 只有Dependencies，没有Tasks
  

在官方Issue里找到了答案：

Gradle task list is large and slow to populate in Android projects. This feature by default is disabled for performance reasons. You can re-enable it in: Settings | Experimental | Do not build Gradle task list during Gradle sync.

Gradle Tasks 由于性能问题默认被关闭了，可以通过以下方式打开：

File -> Settings -> Experimental

去掉下面的勾选

Do not build Gradle task list during Gradle sync

重新sync工程后，就能看到Gradle Tasks了。
