Intelli J IDEA takes forever to update indices

Question

There are several answers in the Forums for different IntelliJ Versions, here is what I´ve tried (IntelliJ 13).

• Give more Memory. Does not help anything with the 'Updating indices'
• Delete .idea and iml in project. Does not help.

In the end what resolved my problem with 'Updating indices' was:

• delete 'caches' folder in user/.IntellIJIdea13/system/

I tried deleting the cache and it works perfectly. Thanks for the solution friends.

Just:

1. Open IntelliJ IDEA
2. Select the File menu
3. Select the Invalidate Caches / Restart... menu.
   Once selected you get a pop-up with a bunch of options.
4. Select Invalidate and Restart
   and before doing that make sure you saved all your changes else it might delete some unsaved changes.

Once you hit that, IntelliJ will restart and then you can see that all the indexing is done really fast.

Delete caches in library folder

rm -rv ~/Library/Caches/IdeaIC15/caches/

On Mac OSX the location of cache is ~/Library/Caches

In Intellij 2020.2 I faced this problem too. Restart/Invalidating cache didn't work for me. What I did was just deleting the cache folder in the following path:

C:\Users\davoud\AppData\Local\JetBrains\IntelliJIdea2020.2
