Build.gradle 文件损坏

Question

I have opened one of my projects after a month, and all the gradle scripts seems to have been affected. All the code of build.gradle files( both app and module level) is gone. I tried running the app on my phone ,it gave the following error Manifest Merger failed , i tried the solution mentioned by Vishrut Mavani and app worked fine. But my question is what happened to all the code in build.gradle files. I had implemented many dependencies, if code is gone, how the app is still working?
I am posting the pictures of build.gradle files.

Other files in gradle scripts are also affected i think, but i am not sure. If anyone need the images, I will post them.

Try the following :

1. In your Gradle file, right-click, from the popup menu select Local History > Show History , from the Old Changes list, select an old change from a month ago, copy your code from there and paste into the Gradle file.

2. Android Studio > Build > Clean Project & Android Studio > Build > Rebuild Project

3. Android Studio > File > Invalidate Caches/Restarts...
