Have equivalents to Eclipse error markers about mapstruct-idea

[mkrumpholz]

Yeah, this should be implemented to see the errors earlier. Now the error is visible at compile time. This is OK but it could be visible earlier, just do the same checks and add an error highlighter. IDEA runs the implemented checks in the background. :)

@mkrumpholz we do have some checks and inspections.

What Gunnar was referring to (I think) is to get the warnings / errors from the compiler and not reimplement the same logic as we have in the Mapstruct code generator. I don't know much about the Eclipse plugin, but from what I've seen the Eclipse plugin uses the compiler output to show the error markers.

Do you have some ideas for how to achieve this @mkrumpholz?

IntelliJ parses the code and builds the internal tree (PSI). I think you know that when you're on plugin development. The checks are part of that process and i would expect that you could have a bit more generic code as a module to use it in the code generator as well as in the code analysis in the IDEA plugin. And i think @gunnarmorling is talking about the error highlighting in IDEA that is not asking the java compiler for the errors but using its own checks.
