我正在尝试使用Spring Data和Neo4j。我开始尝试遵循这个由主站点链接的指南。特别地,我基于“Hello, World!”示例文件创建了pom.xml。这是从我的pom.xml中截取的导致问题的插件…

我看到的错误是:

 Multiple annotations found at this line:
    - Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.0:compile (execution: default, phase: process-classes)
    - Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.0:test-compile (execution: default, phase: process-classes)

我运行的是Eclipse 3.6.2和m2e 0.13。我不是Maven专家,所以如果可能的话,请在您的回答中说明清楚。

我也尝试了m2e 1.0.0通过这个更新网站,仍然得到相同的错误。


当前回答

我在更新m2e后遇到了完全相同的问题,并通过重新安装Maven Integration for Eclipse WTP解决了这个问题。

事实证明,我卸载它时试图从版本0更新m2e。X到1.x

其他回答

见https://www.eclipse.org/m2e/documentation/m2e-execution-not-covered.html。

To solve some long-standing issues, m2e 1.0 requires explicit instructions what to do with all Maven plugins bound to "interesting" phases of project build lifecycle. We call these instructions "project build lifecycle mapping" or simply "lifecycle mapping" because they define how m2e maps information from project pom.xml file to Eclipse workspace project configuration and behaviour during Eclipse workspace build. Project build lifecycle mapping configuration can be specified in project pom.xml, contributed by Eclipse plugins and there is also default configuration for some commonly used Maven plugins shipped with m2e. We call these "lifecycle mapping metadata sources". m2e will create error marker like below for all plugin executions that do not have lifecycle mapping in any of the mapping metadata sources. Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-antrun-plugin:1.3:run (execution: generate-sources-input, phase: generate-sources) m2e matches plugin executions to actions using combination of plugin groupId, artifactId, version range and goal. There are three basic actions that m2e can be instructed to do with a plugin execution -- ignore, execute and delegate to a project configurator.

请注意,目前Eclipse Neon发布系列中提供的M2Eclipse (m2e)版本1.7.0支持指定生命周期映射元数据的新语法。结果是这样的样板文件(这里我们告诉m2e忽略目标):

<pluginManagement>
  <plugins>
    <!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->
    <plugin>

            <pluginExecution>
              <pluginExecutionFilter>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <versionRange>[1.5.0,)</versionRange>
                <goals>
                  <goal>exec</goal>
                </goals>
              </pluginExecutionFilter>
              <action>
                <ignore></ignore>
              </action>
            </pluginExecution>
          </pluginExecutions>
        </lifecycleMappingMetadata>
      </configuration>
    </plugin>
  </plugins>
</pluginManagement>

可以在插件的执行节点中替换为一行:

<?m2e ignore?>

有关详细信息,请参阅发行说明。

我在使用Eclipse v3.7 (Indigo)和m2eclipse时遇到了与Maven插件相同的问题。通过在插件定义中显式地声明执行阶段,这个错误很容易解决。 我的pom是这样的:

<project>
    ...
    <build>
        ...
        <plugins>
            <plugin>

                <groupId>org.codehaus.mojo</groupId>
                <artifactId>buildnumber-maven-plugin</artifactId>
                <version>1.0</version>

                <configuration>
                    <timestampFormat>yyyy-MM-dd_HH-mm-ss</timestampFormat>
                </configuration>

                <executions>
                    <execution>
                        *<phase>post-clean</phase>*
                        <goals>
                            <goal>create-timestamp</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
        ...

Eclipse m2e文档中的建议解决方案:

Use quick-fix on the error in pom.xml and select Permanently mark goal run in pom.xml as ignored in Eclipse build - this will generate the required boilerplate code for you. To instruct Eclipse to run your plugin during build - just replace the <ignore/> tag with <execute/> tag in the generated configuration: <action> <execute/> </action> Alternatively you can instruct Eclipse to run the plugin on incremental builds as well: <action> <execute> <runOnIncremental>true</runOnIncremental> </execute > </action>

如果您正在使用Eclipse Juno,则可能是Eclipse WTP的Maven集成问题。所以从Eclipse Market Place安装同样的程序。

在Eclipse IDE中 帮助>>Eclipse Market Place >>键入查询wtp,它将显示maven集成Eclipse wtp为Juno,安装它并更新maven依赖项和享受
