Hi guangyuan, have you done this successfully now? >From my experience, this is not only a configuring problem. I'm not sure if anyone who really has done this before in IDEA.
There are several places in Calcite which uses Janino for codegen, such as JaninoRelMetadataProvider[1] and EnumerableInterpretable[2]. Actually they are using Janino differently, JaninoRelMetadataProvider is compiling a whole class string, while EnumerableInterpretable is compiling the class body (without class declaration statement). I could debug the generated code from JaninoRelMetadataProvider, but I could not do it for EnumerableInterpretable. The reason is that Janino only put the class body into the file, then IDEA could not find the real class cause it does not exist actually.
