I am running IntelliJ 15 Ultimate and trying to enable the Tomcat plugin (which for some reason was disabled). However, IntelliJ does not seem to let me re-enable it.

enter image description here

What I have tried is

  • Re-install IntelliJ 15, and I chose to replace the old version, but the problems with the plugin seem to be persistent

  • Deleting /Applications/IntelliJ IDEA 15.app/Contents/plugins/Tomcat between the re-installs to ensure it was not being re-used, but with no avail

  • Verifying that I have a licensed/paid version of IntelliJ 15 Ultimate edition

At this point I'm not sure what to do, as a re-install clearly did not work. Are there any directories or files I could manually change/remove?

I am using OS X version 10.11.2 is that matters.

  • I'm using WIN so I can't verify on MAC, but I believe it'd be similar. IJ usually has a `.IntelliJIdea` folder in your home dir. Can you check whether it's writeable? – Morfic Jan 18 '16 at 16:47
  • Issue solved for me after [enabling Java EE: EJB, JPA, Servlets plugin](https://www.jetbrains.com/help/idea/2016.2/enabling-jpa-support.html#plugin). You don't need to re-install idea. – Not a bug Oct 04 '16 at 10:58

You need to enable the "Java EE: EJB, JPA, Servlets" plugin as well. The message is displayed because that plugin is not enabled, and the Tomcat plugin depends on it.

  • I tried that, but the same error message appeared when trying to enable these. They were enabled but when i tried to toggle them off and on again, I got the same error message. – whirlwin Jan 18 '16 at 19:48

The only solution I could come up with was to entirely wipe IntelliJ and any config files it created as described in this answer.

Upon installing IntelliJ once again, the Tomcat plugin was enabled and was able to create a run configuration for that! Maybe not a fix per se, but it works as expected again.
