How to clean project cache in Intellij idea like Eclipse's clean?

Question

Sometimes the IDE makes some error because of the cache. In Eclipse, we can use clean to solve the problem. But how can I do this in IntelliJ?

Answer 1

Try this:

Go into Settings (File > Settings or ctrl+alt+S). Under Project Settings, select the "Compiler" node. On the left, uncheck "Clear output directory on rebuild".

Note that this is a per project setting. If desired, change it in the project template settigs (Settings > Other Settings > Template Settings).
