Not a #cursive but I'm getting com.intellij.openapi.actionSystem.impl.ChameleonAction cannot be cast to com.intellij.openapi.actionSystem.DefaultActionGroup on lein plugin for intellij Then I cant start the repl because REPL run configuration is incorrect - no module selected Anyone else with this problem?

@souenzzo Do you have the lein plugin installed as well as the Cursive one?

If so, that’s officially deprecated and superceded by Cursive - Cursive does all that did and much more, and there will be confusion if you have both.
