REVISED: got a new error after upgrading to AS(3.2.1) and Gradle(4.6).

Tried many solutions including Invalidate Caches/Restart, Close and Import Project, remove cache file, reinstall Android Studio, Clean & Rebuild. None of them could make the project build successfully.

Any other possible solutions?

Answer 1

Try deleting your gradle caches. For example, on Windows:

C:\Users\[username]\.gradle\caches

then perform the following:

1. Android Studio>File>Sync with File System
2. Android Studio>File>Sync Project with Gradle Files
3. Android Studio>Build> Clean Project
4. Android Studio>Build> Rebuild Project
