Kotlin Plugin not available for 126.232

I tried to follow the instructions from the Kotlin wiki's "Getting Started" page and I had the following problems:

  • When I browse plugins in IDEA, the stable plugin does not show in the available plugins list
  • If I add the weekly or nigltly plugin repo, the plugin shows, but when I try to install, IDEA downloads it and nothing happens - no message in the log either
  • If I manually download the nightly version and try to install from zip file, IDEA pops a message box telling me that the Kotlin plugin is not compatible with this version (again no message in the log)

126.232 is not supported by the current Kotlin plugin. Only 12.0.4 is supported
