*Imported from [IDEA-208719](https://youtrack.jetbrains.com/issue/IDEA-208719) · Type: Exception · Votes: 0*
*Comments, attachments, dates and reporter are not part of the export — follow the link above for the full history.*

Start by reproducing the exception in a Grails app by changing the project SDK, then trace the reported path through org.jetbrains.plugins.grails.plugins.ImplKt and GrailsPluginsNode.kt. Compare the indexing call with IndexNotReadyException.create and verify that changing the SDK no longer produces this stack trace.
