Eclipse Compiler including annotation processing

Hey,

I'm using IntelliJ 2021.2.3 CE. I want to use eclipse compiler on my multiproject build. In addition I'm using annotation processing to generate java code e.g. with the google-auto-value library.

But the compiler process fails with 

Warning:java: Could not write generated class XYZ: javax.annotation.processing.FilerException: Source file already exists : XYZ

the java code isn't generated when this message appears.

I added comments already to

https://youtrack.jetbrains.com/issue/IDEA-211545

https://bugs.eclipse.org/bugs/show_bug.cgi?id=547010

without getting an answer.

There is also a project you can checkout to verify the issue in intellij

https://github.com/mbauhardt/ecj-filer-exception

 

My question here is, has someone of you experience with annotation processing in combination with the eclipse compiler?

 

thx

marko

hi Andrey Dernov

thanks for looking into it. did you changed the the class coffee after the first compiling? e.g. adding a line or change the signature of one of the methods? and trigger a recompiling then?

this is the actual issue....
