Problem solved by the feature

With the migration to the central-publishing-maven-plugin, the .buildinfo files are not published anymore since Gson 2.13.2:

• 2.13.1
• 2.13.2

Feature description

Apparently that is a limitation of the plugin being used, so either:

• wait until support central-publishing-maven-plugin for detectSkip apache/maven-artifact-plugin#173 is fixed
• try setting detectSkip to false, and add a comment referring to the maven-artifact-plugin issue
  (not sure if that has undesired side effects)

Alternatives / workarounds

Don't generate .buildinfo anymore and remove the <goal>buildinfo</goal> execution from the maven-artifact-plugin configuration in Gson. But don't remove the complete maven-artifact-plugin entry since it is executed as part of the GitHub CI.
