Running Maven plugins which work only with Java 8 as part of the Maven Project Builder

[digulla]

I have an old project which uses jaxb2-maven-plugin. The verson we use only works with Java 8 (missing XML classes in 11 and up).

Since Eclipse 2022-06 (4.24) uses Java 17, I'm getting errors in the project since the plugin fails.

Is there a trick to get m2e to run the plugins with a different Java version than the IDE? Or do I have to upgrade jaxb2-maven-plugin? (I can't upgrade the whole project to 11, so I'd need to find a newer version of jaxb2 which runs with both versions).

Not really, you can run the m2e maven build with a different java but not the plugin itself, as m2e is running "inside" eclipse

Or do I have to upgrade jaxb2-maven-plugin? (I can't upgrade the whole project to 11, so I'd need to find a newer version of jaxb2 which runs with both versions).

You should upgrade your build to run with java 11, the project can still be java 8.

By the way it should be possible to add missing stuff to the <dependency> section of the plugin

Great idea. I'll try that.
