Maven plugin does not work in Eclipse m2e

[grobitto]

Set up schema generation in my Eclipse project, but the result was empty "paths". The java class is just a simple resource with @path and @get annotations.

{
  "openapi" : "3.0.3",
  "info" : {
    "title" : "Generated API",
    "version" : "1.0"
  },
  "paths" : { }
}

Running maven from command line - everything is okay and schema generated correctly. I am using latest eclipse version and latest m2e plugin.

Just confirmed this is not my eclipse configuration problem: I've downloaded fresh Eclipse 2023-03 and the problem is still there.

@grobitto , thank you for opening this. It would be helpful if you could attach or link a small project that has the problem. That just makes it easier to jump in and start diagnosing the issue.

Hi,
Same problem with my spring boot project. Nothing or almost nothing in the output file.
I'm using open api 3 annotations in my code. I cannot share my project.
Any idea about this bug?

Thanks

[MikeEdgar]

@grobitto , @darkmoonbzh please use release 3.5.1 of the plugin which should be available in Maven central shortly.

@MikeEdgar Can you also please backport the fix to 2.3.x? I tried to cherry-pick this commit, and it seems to be all good except some de-jakartification is needed, but have not yet succeeded in creating an environment where I could build even the original code.

[MikeEdgar]

@tuffnatty , we can probably do that, but I'm curious what would prevent upgrading your plugin to the latest version? Is there another breaking change somewhere?

[tuffnatty]

@MikeEdgar Sure, it's JDK 1.8 compatibility, that's why 2.3.x still gets any updates, isn't it?

[tuffnatty]

@MikeEdgar BTW I managed to build a 2.3.2-SNAPSHOT and so there's a PR: #1604 but it's basically, as I already said, just cherry-pick + de-jakartification.
