my IDEA version is 2018.2 182.3684.101
After the update, I found that I kept flashing updating indices and scanning files to index,2 seconds. I tried
fild- > Invalidate Caches / Restart
to no avail.
this problem does not exist in another project.
it doesn"t work even if I delete the .idea in the project directory. Has anyone ever encountered this problem? How to solve it?
