Question

How can I get rid of the following m2eclipse warning?

maven-war-plugin goals "inplace", "exploded", "manifest" are ignored by m2e

Answer 1

As far as I can tell, this warning is being emitted from m2e-wtp, which provides a set of m2e connectors that work with Eclipse Web Tools Project (WTP).

m2e-wtp includes a lifecycle-mapping-metadata.xml file that contains:

    <pluginExecution>
      <pluginExecutionFilter>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <versionRange>[1.0,)</versionRange>
        <goals>
          <goal>inplace</goal>
          <goal>exploded</goal>
          <goal>manifest</goal>
        </goals>
      </pluginExecutionFilter>
      <action>
        <ignore>
            <message>maven-war-plugin goals "inplace", "exploded", "manifest" are ignored by m2e</message>
        </ignore>
      </action>
    </pluginExecution>
  </pluginExecutions>

Thus, I don’t think there is a way to suppress this warning, other than to (1) stop using m2e-wtp or (2) downgrade to version 0.14 of m2e-wtp, as this warning was added in 0.15.
