Plugin error: execution not covered by lifecycle configuration

问题

I am trying to use the maven-warpath-plugin available here. But I keep getting an error in my pom.xml file that says:

Plugin execution not covered by lifecycle configuration: org.appfuse.plugins:maven-warpath-plugin:2.1.0:add-classes (execution: default, phase: generate-sources)

How do I resolve this? Here is my pom.xml snippet for the plugin:

<plugin>
    <groupId>org.appfuse.plugins</groupId>
    <artifactId>maven-warpath-plugin</artifactId>
    <version>2.1.0</version>
    <extensions>true</extensions>
    <executions>
        <execution>
            <goals>
                <goal>add-classes</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Eclipse offers me a quickfox tip to "discover new m2e connectors" to resolve this error. I have installed most of the connectors available that seem to apply but the error is still there. Any ideas how I could make this work?

回答1:

This is the new behaviour of m2e (which replaced the old m2eclipse plugin). To specify what eclipse should do with the plugin you have to configure the build lifecycle mapping in the project's pom.xml - or install a connector (which decides if the plugin needs to be executed in an eclipse build or not) if it exists.

As there seems to be no connector for the maven-warpath-plugin yet you have to define the behaviour in the pom. You can use the second eclipse quickfix for this (Permamnently mark goal add-classes in pom.xml as ignored in eclipse build). This will add the following section to your pom:

<build>
    ......
    <pluginManagement>
        <plugins>
            <!--This plugin's configuration is used to store Eclipse m2e settings 
                only. It has no influence on the Maven build itself. -->
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>
                                        org.appfuse.plugins
                                    </groupId>
                                    <artifactId>
                                        maven-warpath-plugin
                                    </artifactId>
                                    <versionRange>
                                        [2.1.0,)
                                    </versionRange>
                                    <goals>
                                        <goal>add-classes</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <ignore></ignore>
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
</build>

You can change the <ignore> action to <execute> if you want to process the plugin in each eclipse build (on import, clean, ...).

The plugin configuration is eclipse specific and does not make the pom.xml look nicer - but at least it has no influence on the Maven build....
