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

I was having the same issue, where:

No marketplace entries found to handle build-helper-maven-plugin:1.8:add-source in Eclipse. Please see Help for more information.

and clicking the Window > Preferences > Maven > Discovery > open catalog button would report no connection.

Updating from 7u40 to 7u45 on Centos 6.4 and OSX fixes the issue.
