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…

<plugin>

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

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.

其他回答

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>

我在SpringSource Tool Suite 2.8.0升级Maven集成的博文中修复了它。

遵循“哦,我的项目不再构建”部分的建议。即使它是为SpringSource Tool Suite设计的,我也用它来修复常规的Eclipse安装。我不需要修改我的pom文件。

我在maven节俭插件中遇到了完全相同的问题。这是我的解决方案,不需要搞砸你的pom.xml:

使用命令行maven实用程序mvn mvn eclipse:月食 创建一个eclipse项目 在eclipse中导入项目。记得使用 文件>导入>通用>现有项目到工作区 将项目添加到工作区中。

这应该能解决问题。

作为前面答案的补充——如果您不能或不想将所有这些样板文件添加到您的项目POM中,我发现了一个变通方法。如果你看下面的位置:

{Eclipse_folder}/plugins/org.eclipse.m2e.lifecyclemapping.defaults_{m2e_version}

您应该可以找到一个名为lifecycle-mapping-metadata.xml的文件,您可以在其中进行与其他答案中描述的相同的更改,以及M2E插件执行中没有涉及到的更改。

你可以在eclipse中抑制这个错误: 窗口->首选项-> Maven ->错误/警告
