I've been trying to create a tool to perform class/methods/field name migrations for Kotlin files. I have tried using the kotlin-compiler package to parse the Kotlin files, perform PSI renaming transformations, and then write the transformed PSI as text. However, when I try to use the PSI add and replace methods, I get the following error:

java.lang.IllegalArgumentException: Missing extension point: com.intellij.treeCopyHandler in area null

Is this the right way of going about this? If it is, how do I resolve this error?

[raulraja]

The CLI compiler uses an immutable PSI tree

#arrow-meta works around it using a parallel representation when performing transformations on the AST and recreating the KtFile

Is it possible I can use this for my own project?

[raulraja]

yes

you can copy the internals or rethink your plugin with Arrow Meta if you find it suits your problem.
