IntelliJ-Haskell throws IllegalStateException after update IDEA to 2018.3.1

I just updated IDEA to 2018.3.1 (details see below). After Restart the IntelliJ-Haskell plugin throws the following exception, without opening a Stack project.

Stacktracke:

@AllanWang Yes, you’re right. Still have some issues to solve before releasing version 1, publish to stable repo channel and update github readme.

Are there plans to update the plugin listing? It’s still at beta12

I see that it requires a new repo url now. Not sure what happened but it’s slightly confusing for new users who found the plugin through the repo rather than the github readme
