title: How to clean plugin dev cache in Intellij
body: <p>I have a question about plugin development and IntelliJ. I'm developing a plugin to IntelliJ 12, and I have attached community sources. When I try to run my plugin (which has it own configuration under File &rarr; Settings &rarr; MyPlugin) and I check if configuration is visible, I don't see it. I know that it is working, because on another PC I checked it and configuration is visible (I didn't run the plugin earlier, it was first run, and configuration was visible). </p>
  
  <p>I think that the IntellijJrun the configuration on the Community Edition which I have attached and on computer where I didn't saw configuration, I ran plugin few times before I have added that configuration.
  When I run plugin, I see the message that cache wasn't cleared, and I think that this is the issue why I don't see configuration under File &rarr; Settings. </p>
  
  <p>So the question is: how can I clear the cache on the testing instance of IntelliJ? I read that in IntelliJ 13 there is an option under File menu, but in 12, this option is not available.</p>
