IntelliJ bad plugin how to start

Question

Hi I have just started using IntelliJ again and have version 9. I just installed the Mercurial plugin and now the ide won't start anymore. Has an error of

Fatal error initializing class com.intellij.openapi.actionSystem.ActionManager:
java.lang.VerifyError: class com.dcx.hg.MercurialVcs overrides final method getName.()Ljava/lang/String;

I now know that I should be using the plugin hg4idea

Is there a way I can remove this plugin so I can start the ide, I am sure there must be..

Thanks in advance.

Answer 1

If you look in the directory where you installed IntelliJ, you'll see a /plugins directory. Perhaps if you delete the Mercurial plugin folder you'll be able to restart the UI. Worth a try. NOTE: Check here for OS/version related plugin path.

Answer 2

I am running on a Mac, the Plugin directory is located in ~/Library/Application Support/IntelliJIDEA60/ You can just delete the offending plugin. Note, depending on your edition of the IDE, the directory may be different. For example, IdeaIC2016.3

Version 11 for Windows stores plugins also in c:\Users\<username>\.IntelliJIdea11\config\plugins\ so delete plugins from that location as suggested by @duffymo.

Answer 4

Ran into the same problem with another plugin. The solution was to remove the offending plugin folder or jar from the Plugins folder - see the exact location below for your OS.

The locations of the user plugins folder for different platforms are listed at https://intellij-support.jetbrains.com/entries/23358108-Directories-used-by-the-IDE-to-store-settings-caches-plugins-and-logs:

OSX

Configuration:

~/Library/Preferences/<PRODUCT><VERSION>
# e.g.:
~/Library/Preferences/IntelliJIdea14

Caches:

~/Library/Caches/<PRODUCT><VERSION>

Plugins:

~/Library/Application Support/<PRODUCT><VERSION>

Logs:

~/Library/Logs/<PRODUCT><VERSION>

Linux/Unix

~/.<PRODUCT><VERSION>

Windows

Windows Vista, 7, 8:

<SYSTEM DRIVE>\Users\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>

Windows XP:

<SYSTEM DRIVE>\Documents and Settings\<USER ACCOUNT NAME>\.<PRODUCT><VERSION>

Answer 5

Version 15 on Ubuntu:

cd ~/.IntelliJIdea15/config/plugins
rm -r <offending_plugin>
