In intellij, how to refresh project after changing build.sbt

Every time I change the build.sbt, it gives hints to refresh project or ignore. I recently click the ignore by mistake, and it never gives me the hints any more. So I can't refresh it any more, and after editing the build.sbt, the project still uses the old configuration.

Where is refresh option in IntelliJ?

To run Standard Refresh, click the Refresh toolbar button. or press Ctrl+F5 . To run Force Refresh, click the Force Refresh toolbar button.

How do I clear my sbt cache?

You can use Pretty Clean to clean the all of dev tools caches including SBT. PrettyClean also cleans the SBT project's target folder.

You can force SBT to reload changes: Open SBT toolwindow (on the right side of IDE) and press refresh button.

If you use auto-import feature you need to save your file to force auto-refresh.
