IntelliJ IDEA hangs while "Finished, saving caches"

Question

Each time I do a make (a Java project) in IDEA, the compile process is hanging stating "Finished, saving caches". I have to kill this process before I can continue. I tried to use File -> Invalidate Caches without success.

Any ideas?

Answer 1

One more workaround is adding your mac's hostname to /etc/hosts file along with localhost like the following:

127.0.0.1 localhost <hostnameOfMac> ::1       localhost <hostnameOfMac> 

This solved the problem for me.

Answer 2

According to JetBrains,

IntelliJ IDEA caches a great number of files, therefore the system cache may one day become overloaded. In certain situations the caches will never be needed again, for example, if you work with frequent short-term projects. Also, the only way to solve some conflicts is to clean out the cache.

Go to the menu File | Invalidate Caches/Restart and take it from there.
