Importing project in Eclipse results in warning about unknown Maven plugin

Project generated with archetype 2.01.00-alpha-1.
After generating project, importing it in Eclipse, there is a popup dialog asking the user for input about a Maven plugin it does not recognize:

No marketplace entries found to handle build-helper-maven-plugin:1.9.1:regex-property in Eclipse. Please see Help for more information.

Not a blocker but annoying. Perhaps we can solve this like we did for the filesync plugin.
