no scala library recognized after update to newest eap build?

I had this problem with existing .idea projects. I found that deleting .idea and .idea_modules and importing the sbt-based project directory anew solved this. You have to be patient until the whole import process has finished (background task). I also remember having had problems when switching from 1.2 to 1.2.1, where I needed to switch the JDK version forward and backward if I didn't want to wipe the .idea folder.

I hope that helps. Best, .h.h.

When you get symptoms like these, especially after a version update, the
cache is often the problem. On the Mac, under the File menu, there's an
option to invalidate the caches and restart.

i tried to go back to an older version - but even with the official releases 14.0.2 & 1.2.1, the problem persisted. reimporting my sbt project didn't change anything, invalidaing caches didn't change anything.
what are the things i should try to get it working again?

Thanks!  I had the same problem and clearing the caches worked for me.  I rarely have to do it so I forget.. :)

I've had to do the cache invalidation thing three times today.  For some reason it just forgets about my Scala.  Modules still have scala-library as a dependency.

I am upgraded to version 1.2.35.2.EAP of the plugin, IU-139.872.1 of Intellij today.  I am using Maven (not sbt).

Thanks,

I ended up switching back to 14.0.2.  I had to blow away my .idea and .iml and invalidate the cache.

It's https://youtrack.jetbrains.com/issue/SCL-8025
I finally found problem in JIT when b & 0xFF calculates to b after JIT. I replaced it by appropriate if/else (by sign of b) and reproducible example I had became ok.
So you can try scalap.jar from issue, which I attached earlier, or just wait for the next update, when I'll finally release it.

Thanks! I'll check the next one.
