Invalidate caches

Last modified: 05 October 2021

When you invalidate the cache, CLion removes the cache files for all projects ever run in the current version of the IDE. The files will be recreated the next time you open these projects.

Note the following before you proceed:

  • The caches will not be deleted until you restart CLion.

  • Opening and closing a project without invalidating the cache does not result in deleting any cached files.

  • Local History is not deleted when you invalidate the cache unless you explicitly enable this option in the Invalidate Caches dialog. However, mind that Local History has a retention period of 5 working days by default.

Clear the system cache

  1. From the main menu, select File | Invalidate Caches.

    The Invalidate Caches dialog

  2. In the Invalidate Caches dialog, you can select additional actions that the IDE will perform while removing the cache files:

    • Clear file system cache and Local History: remove the virtual file system cache together with the information stored in Local History.

      This action might be helpful for troubleshooting purposes when the usual cache invalidation is not enough to solve the problem.

    • Clear VCS Log caches and indexes: remove the cache and indexes of the VCS Log.

      Enable this option if you are certain that your VCS Log indexes are broken, for example, if the Log search doesn't work correctly.

  3. Click Invalidate and Restart.

    If you click Just restart, cache files won't be deleted, and the selected optional actions won't be applied.

    tip

    We recommend that you restart the IDE via Find Action: press Ctrl+Shift+A and type Restart IDE.

For details on where various user-specific files are stored, see Directories used by the IDE.
