jenkins - 无法解析的父POM无法找到工件,'parent.relativePath'指向错误的本地POM

Question

我有一个关于jenkins构建的问题.正如标题所描述的那样,"无法解析的父POM无法找到工件而'parent.relativePath'指向错误的本地POM"问题,经常在stackoverflow上找到,但我没有找到匹配的问题.所以这是我的问题描述

我的项目结构如下所示:

/root-project
 +-----------/pom.xml
/root-project/modul-a/
 +-------------------/pom.xml
/root-project/modul-b/
 +-------------------/pom.xml
/root-project/modul-c/
 +-------------------/pom.xml

在我的本地机器(Windows)上,我可以从/建立我的项目:

mvn -f root-project/pom.xml clean install

没有错误,即使有一个空的存储库.

但是jenkins(linux)无法做到这一点.

所以这就是我母亲家里的东西

<?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>

还有一个模块pom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>

正如我在其他条目中所提到的那样,但它没有改变结果.它为什么要指向存储库,父节点从未存在过.所以有人建议我做错了吗？

正如这里所要求的那样是mvn帮助的输出:effective-pom:

Answer 1

在<artifactId>对你的榜样模块POM你的父母是root-project.

在<artifactId>你的父POM是prject.在jenkins输出中,似乎正在解析工件的名称rootproject.尝试将父母的pom设置<artifactId>为root-project(注意额外的' - ').

我不确定这是如何在你的机器上构建的.你可以mvn help:effective-pom在你的机器和运行jenkins的机器上发布运行的输出吗？

为了它的价值,您可以启用-X调试输出的标志,以查看Maven可能尝试采取的操作.我发现这对我调试Maven项目的配置很有用.
