Plugin execution not covered by lifecycle configuration for maven-plugin-plugin in m2e 1.5.x / Eclipse Luna

Question

After upgrading to Eclipse Luna or to m2e 1.5.x and opening an existing workspace with Maven plugin projects, Eclipse complains that

Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-plugin-plugin ...

Answer 1

You need to tell m2eclipse how to treat the plugin execution.

If the message is for instance: Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-plugin-plugin:3.2:descriptor

Use following snippet:

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.apache.maven.plugins</groupId>
                                    <artifactId>maven-plugin-plugin</artifactId>
                                    <versionRange>[3.2,)</versionRange>
                                    <goals>
                                        <goal>descriptor</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <ignore />
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>
