Maven报错总结

1. Maven使用过程中的报错总结

  • maven刷新报错’parent.relativePath’ of POM

    1
    'parent.relativePath' of POM com.xxx.web.cloud:xxx-boot-job:1.1.1-SNAPSHOT (D:\code\xxx-build\xxx-boot-job\pom.xml) points at com.xxx:xxx-build instead of com.xxx.web.cloud:xxx-parent, please verify your project structure

    • 原因：parent中指定的父级和modules指定的pom，不是同一个项目

      • 父级指定的

            <version>1.1.1-SNAPSHOT</version>
        </parent>
        <artifactId>xxx-boot-job</artifactId>
        <packaging>pom</packaging>

      • modules中指定的

        <packaging>pom</packaging>
        <modules>
            <module>xxx-boot-job</module>
        </modules>

    • 解决：在parent中添加<relativePath/>，作用：查找依赖父项目的顺序为： relativePath配置的地址 -> 本地仓库 -> 远程仓库，默认值为../pom.xml

          <version>1.1.1-SNAPSHOT</version>
          <relativePath>../xxx-parent</relativePath>
      </parent>

  • 构建报错’parent relativePath’ points at no local POM @ line 5, column 13

    1
    [FATAL] Non-resolvable parent POM for com.xxx.web.cloud:xxx-boot-starter-ribbon:1.1.1-SNAPSHOT: Failure to find com.xxx.web.cloud:xxx-boot-starters:pom:1.1.1-SNAPSHOT in http://xxx.xxx.xxx.xxx:xxxx/repository/maven-public/ was cached in the local repository, resolution will not be reattempted until the update interval of nexus-public has elapsed or updates are forced and 'parent.relativePath' points at no local POM @ line 5, column 13

    • 原因：parent中错误的添加了<relativePath/>,导致构建找不到pom文件

          <version>1.1.1-SNAPSHOT</version>
          <relativePath/> <!-- lookup parent from repository -->
      </parent>

    • 解决：当parent和modules配置一致时，无需指定relativePath，直接删除即可
