Problem with Annotation processing

Answered

Hi,

I am attempting to compile this Folio module, cloned from https://github.com/folio-org/mod-password-validator.git

using

in windows 11.

I am getting this error on compilation.
It looks like there's some sort of file access clash on the code generated by the Mapper annotations.

I am not running maven on commandline at the same time.
If I do compile with maven on commandline, the build completes without error.
I have cleared the cache and done clean rebuilds
If I alter intelliJ to delegate build/run calls to maven, it works. But I shouldn't have to.

Anyone got suggestion on how to fix?

Annotation settings as shown.

Error is as follows (formatted as I get it, no newlines in the original either)

Problem solved.
I had to remove the generated target directories manually, then build in intelliJ and fail, then build in maven, then rebuild in IntelliJ.

hello, in my case I had more or less the same issue, in my case the problem stems from annotation processing settings, apparently Idea is not understanding/seeing the maven setting about annotation processing in the pom so I had to set manually the global settings for annotation processing because apparently Idea was generating mapstruct Impl class in one folder and maven in another
