Nika "run" seems to be gone Follow

It's working for me.
Running Scala program is "Application" run configuration.

I have added two screenshots....

My context menu looks like:


And to do Run application

Check that the Project SDK (pointer to the Java installation) is configured correctly (File, Project Structure, Project, SDK)

Yes it is..i have "Run .." available for Java classes.

BTW when i manually type the name of the Scala object inside the "Main Class" (showing red),  it works.

Which OS are you using?
Few users complained on this bug on MacOS, and unfortunately I don't know how to fix it (I can't reproduce it even on MacOS).

Good news...after a restart it seems to be there. I guess what happened is the following. I first made a class and then changed into an object. Perhaps the fact that it was a class as apposed to an obect was assumed from some caching?

I am running Linux/OpenSuse/KDE.

No, there is no such caching (I also tried to reproduce your steps, all is ok).
So I'll add some diagnostic for this bug. Thank you for your report.
