First of all, I don't think this really belongs to
#kontributors (or I'm missing something maybe, please do correct me in such case) -- this channel is devoted to people who would like to contribute to Kotlin compiler/IDE plugin and have some specific questions about it internals.
Then, you're very welcome to file an issue:
kotl.in/issue. Minimized example is
very appreciated, but at the very least source code will be required -- such errors are very hard to diagnose looking just at the exception. Also, please specify plugin/compiler version you're using.
P.S. Sorry for silly question, but are you sure that you're using the same version of compiler/plugin both when compiling in IDEA and when compiling from maven? This part sounds very suspicious for me
