本文介绍了解决m2eclipse不支持maven-dependency-plugin特定目标的问题方法。通过更换m2e插件版本及在pom.xml中添加pluginManagement配置来避免错误。

近日由于开始接触另一个项目A, 项目A在STS上基于maven搭建, 寤不想用STS, 遂将项目导入eclipse, 然后报以下错误:
[color=red]maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.[/color]
故障排查过程:
1、eclipse已经安装maven插件, 且之前项目无问题
2、遂怀疑, maven插件可能缺失, 但由于之前项目同样用到此功能, 所以排除
3、遂在怀疑插件板本问题, 事实正确, 寤eclipse所装m2e插件来自:http://download.eclipse.org/technology/m2e/releases/, 此版本来自maven社区, 过旧,
解决方案:
1.换装官网版本:http://m2eclipse.sonatype.org/sites/m2e
2.在pom文件的<[color=red]plugins[/color]>标签之前添加如下<[color=red]pluginManagement[/color]>标签，此2个标签平级.如下：
