Problems with M14 plugin

1

Today IDEA (EAP) updated my Kotlin plugin to 0.14.489. Since then, I've been getting this error:

org.jetbrains.kotlin.psi.JetImportDirective cannot be cast to org.jetbrains.kotlin.psi.JetClassOrObject java.lang.ClassCastException: org.jetbrains.kotlin.psi.JetImportDirective cannot be cast to

... repeteadly, multiple times per second.

Also, “println” doesn’t seem to be recognized anymore, or “@Throws”, or some other constructs.

Is there anything I can do? Is this a known problem? Should I try with one of the latest builds for the plugin?

Compiling with gradle with the same version works completely fine…

Tried with the latest successful plugin build (0.14.499, although I didn't change the kotlin stdlib or gradle plugin versions) with the same result...

Could you try to Invalidate caches in your IDE? (File -> Invalidate Caches/Restart -> Invalidate and Restart)

I've updated my dependencies to kotlin-plugin 0.14.450 (which is tagged in TeamCity as M14) for IDEA 142.5047.6 (15 EAP), and kotlin-stdlib 0.14.449 (from Maven central). The IDEA editor, compilation in IDEA and compilation with Gradle all work fine.

Hi,

I tried that already, with no results. I even tried in another computer which, while not throwing those errors to me, still didn’t manage to found any references to “println”, “@Throws” or anything coming from stdlib, it seems (and yes, it’s been referenced from the gradle files, as compiling with the command line works fine)

Also Benjamin is right, for Gradle I used 0.14.449 instead of 0.14.489, but the plugin is definitely 0.14.489.

Moving back to 0.13.1514 works fine.

So, tl;dr; 0.13.1514 seems to work fine, 0.14.489 and 0.14.499 doesn’t… (tried multiple computers with the same project, and invalidating caches and restarting)

I justsaw that there is a download for 0.14.449 on https://plugins.jetbrains.com/plugin/6954?pr=

That one seems to work fine :slight_smile:

Note that version of koltin-plugin in IDE should be the same as the version in gradle, because different versions of Standart library and Compiler could be incompatible, as a result any symbol from library will be unresolved.
