@tomas-langer I added one more commit to handle the last case I had issues with when using Eclipse IDE. Can you have a look at it as well? I signed the OCA already, I guess it needs a bit to be approved. |

This means that it will only work with clean compile and will not be able to do incremental build.

I assume deleting a resource only fails when using ECJ and javac wouldn't fail to delete the fail, right?

@tomas-langer can you have a look at the PR again? I think I addressed all your points. It would be great to gave it to get Eclipse IDE running. |

I fixed the Checkstyle error just now. I don't know what we do with the failing tests/native-image-mp-1-macos job. Could it be flappy? |

Problem
I'm writing a HTTP feature for Helidon (related to #8897) and want to work with Eclipse IDE, but the Helidon annotation processors throw exceptions because the Eclipse Compiler for Java (ECJ) behaves slightly different compared to javac.
Solution
Some changes were necessary to get the annotation processing going:
javax.tools.StandardLocation.SOURCE_PATHimplemented and therefore the search formodule-info.javafails with a thrownIllegalArgumentException. Ignoring this exception when compiling with the ECJ is fine.Elementparameter is null. Returning an emptyOptionalenables the caller to fall back.FileObjectthrows anIllegalStateException. Ignoring any exception when compiling with the ECJ should be fine.I have successfully tested the changes suggested by myself in a recent Eclipse IDE (
