Repair IDE
RubyMine provides the means to refresh and recover cache files in a particular project step by step. Using the Repair IDE action, you can troubleshoot the issues with unresolved code or corrupted caches in your project without invalidating the cache and restarting the IDE. RubyMine processes only the current project during the recovery, so you will not lose the cache files of all projects. Thus, the next time you open a project, you will not need to wait for cache recreation.
RubyMine provides several recovery steps intended to resolve issues you might experience when working in the IDE, for example, when some class isn't resolved or navigation features don't work correctly. After each step, you can check whether the issue persists and decide to continue or complete the recovery process.
In the main menu, go to . RubyMine will automatically launch the first recovery step and refresh the virtual file system.
RubyMine will display a notification that you can use to continue or complete the recovery process. If everything works correctly, click Everything Works Now to complete the recovery process. You can do this after any step of the recovery process.
To continue the recovery process, click Rescan Project Indexes. RubyMine will find all files in your project that aren't indexed and index them.
To move to the next recovery step, click Reopen Project. This will reopen your project without restarting RubyMine.
To move to the next recovery step, click Drop Shared Indexes. This will remove all shared indexes related to your project.
To move to the last recovery step, click Reindex Project. RubyMine will examine your project code to rebuild an index of classes, methods, objects, and other code elements that make up your application.
After going through all the recovery steps, if the issue persists, you can continue with cache invalidation. Click the More link and select Invalidate Caches and Restart.
Repair file-related caches
You can launch the first two steps of the recovery process on a single file in your project.
In the Project tool window (Alt+1) , right-click the file you want to fix and select .
Invalidate external system cache in a Gradle project or a Maven project
Instead of deleting the entire project directory when you encounter problems related to the incorrect synchronization of a Gradle or Maven project, you can invalidate the build system cache and re-sync your project.
From the main menu, select File | Cache Recovery | Invalidate Build System Caches and Re-sync.
RubyMine closes and reopens the project. It also syncs the project again. During this process, the
cache-state.xmlfile is updated.
