我有一个关于Jenkins构建的问题。正如标题所描述的那样，这是一个“无法解析父POM，找不到工件，'parent.relativePath'指向错误的本地POM”的问题，在stackoverflow上经常发现，但我没有找到匹配的解决方案。因此，以下是我的问题描述：
我的项目结构如下：
我的项目结构如下：
/root-project
+-----------/pom.xml
/root-project/modul-a/
+-------------------/pom.xml
/root-project/modul-b/
+-------------------/pom.xml
/root-project/modul-c/
+-------------------/pom.xml
在我的本地电脑（Windows）上，我可以从以下位置构建我的项目：
mvn -f root-project/pom.xml clean install
即使是一个空仓库，也没有错误。
但是Jenkins（Linux）无法做到这一点。

以下是我的父POM中包含的内容：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>root-project</artifactId>
<version>1.3.0-SNAPSHOT</version>
<packaging>pom</packaging>
<modules>
<module>module-a</module>
<module>module-b</module>
一个POM模块的例子
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>root-project</artifactId>
<groupId>org.example</groupId>
<version>1.3.0-SNAPSHOT</version>
</parent>
<artifactId>module-a</artifactId>
<dependencies>
//..
</dependencies>
</project>
正如其他条目中提到的，我已经尝试过，但并没有改变结果。为什么呢？因为它指向存储库，而父级从未存在过。
那么，有人能建议我做错了什么吗？
如要求所示，以下是mvn help:effective-pom的输出：
