An internal error occurred during: "Building": jakarta.json.spi.JsonProvider: org.apache.johnzon.core.JsonProviderImpl not a subtype

[rombert]

A project that I'm working has a module that keeps failing to build in Eclipse + m2e . The error that is reported is java.util.ServiceConfigurationError: jakarta.json.spi.JsonProvider: org.apache.johnzon.core.JsonProviderImpl not a subtype ,

Full stack trace below

This obviously comes from the slingfeature-maven-plugin that the project uses, but I don't know how to fix it:

• it's not a goal, so I can't ignore it
• the error does not appear with the CLI
• I have no idea what classloaders are set up for Maven extensions inside Eclipse

I can reproduce this on an empty workspace by importing https://github.com/rombert/pospai , which points to 4c3ef57084f55fc7ef0ae816613e66d1bedaf482 at this moment.

I'm also open to suggestions for fixes in the plugin, if you see any.
