No IDEA annotations attached to the JDK 1.8 problem fixed

When I opened AndroidStudio today and built the project, I reported the problem No IDEA annotations attached to the JDK 1.8. Please record it and encourage everyone!

Solution on stackoverflow :

1. Close AndroidStudio;

2. Enter the files in the system disk:C:\Users\UserName\.android Back up the build-cache folder and delete it (If you are brave, you can delete it directly), or rename it;

3. Enter the files in the system disk:C:\Users\UserName\.AndroidStudio3.4\system Back up the following folders Then delete or rename:

4. Open AndroidStudio, compile the project, and all the above files will be generated again, which is a perfect solution;

5. Delete the backup, or rename the folder.
