Error:Unexpected lock protocol found in lock file. Expected 3, found 0

Question

After upgrading Android Studio to 1.3, I can't compile my project anymore. I am getting Unexpected lock protocol found in lock file. Expected 3, found 0.. I have tried with deleting my .gradle folder but that does not solve the problem. Anything else I can do?

Answer 1

I have solved it by deleting the folder

c: \ users \ [myusername] \ .gradle \ caches \ 2.14.1

After reopening Android studio it was all fine

Answer 2

okay here's very lightweight solution with steps:

• Ctrl+Alt+Shift+S or File->Project Structure

• Select Project from left panel

• Now check your Gradle Version at right panel

• In my case my Gradle Version is 3.3

• Navigate C:\Users\ashish\.gradle\caches and delete your Gradle Version - 3.3 named folder.

• Now restart or open your project again from workspace.

Greetings...your problem is solved.
