java.lang.annotation.AnnotationTypeMismatchException

[Huxpro]

Are there any way to debug this? I assume I annotated something wrong by not extending LanguageServer after #321 The stack trace is not quite helpful.

same problem

Looks like a Scala-specific issue. Could you try with specific values for all annotation parameters, e.g. @JsonRequest(value="textDocument/completion", useSegment = false)?
