Remove the warnings in m2e in eclipse

[stickycode]

Need to add a metadata file like this

<lifecycleMappingMetadata>
  <pluginExecutions>
    <pluginExecution>
      <pluginExecutionFilter>
        <goals>
          <goal>fetch</goal>
        </goals>
      </pluginExecutionFilter>
      <action>
        <ignore/>
      </action>
    </pluginExecution>
  </pluginExecutions>
</lifecycleMappingMetadata>

in META-INF/m2e/lifecycle-mapping-metadata.xml

as per https://www.eclipse.org/m2e/documentation/m2e-making-maven-plugins-compat.html
