m2e lifecycle-mapping not found

Question

I am trying to use the solution described here to solve the annoying \"Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:build-helper-maven-plugin:1

Answer 1

It happens due to a missing plugin configuration (as per vaadin's demo pom.xml comment):

This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.
