'parent.relativePath'指向我的com.mycompany:MyProject而不是org.apache:apache - 为什么？

Question

这是真的是Solr项目目录在MyProject父目录中(但是2之间没有模块或任何maven关系,只是FS方便)​​.我必须把它放出去吗？

$ mvn -DskipTests clean install

来自pom.xml:

<parent>
    <groupId>org.apache</groupId>
    <artifactId>apache</artifactId>
    <version>8</version>
  </parent>

$ pwd
/Users/simpatico/ws/MyProjectBaseDir/solr

Answer 1

添加一个空 <relativePath>,<parent>以便从存储库中解析父pom.

  <parent>
    <groupId>org.apache</groupId>
    <artifactId>apache</artifactId>
    <version>8</version>
    <relativePath></relativePath>
  </parent>

这是相关的文档.

此功能仅用于增强该项目的本地结帐的开发.如果要禁用该功能,请将值设置为空字符串,并始终从存储库中解析父POM.
默认值为:../pom.xml.

Answer 2

要么忽略警告,要将源移出不相关的父项,要么输入正确的元素值.这个问题是由relativePath的默认值引起的,它是../pom.xml,默认值被注入你的有效pom,触发警告.
