maven - Intelli J IDEA takes forever to update indices

Question

Is it normal for Intelli J to take a lot of time (almost 12 hours) to update indices for a project? I just installed Intelli J on my machine and imported a rather large Maven project (13k+ files).

I understand that the project is large but I let my computer up all night and when I woke up in the morning, Intelli J still hasn't finished updating the indices for the files yet, which makes it impossible to do anything since the popup with title 'Updating Index' keep hanging there in the middle of the screen.

Answer 1

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/
