Does this occur for the latest stable release (i.e. version 2.3.1) as well?

lennartj commented 6 years ago

M2E / Eclipse integration was fixed in release 2.3.1 of the plugin. Upgrade to that version to remove the exception.

I'm having the same problem. This is the configuration i have in the pom

I can confirm this issue in newer Eclipse versions. I think it wasn't there back in Eclipse Oxygen (from 2018). Upgrading to release 2.3.1 did help, at least for Eclipse 2020-06.

There also seems to be a workaround: generate the sources by running a regular Maven build -> the error goes away once the generated folder or sources exist.
