jenkins - 無法解析的父POM無法找到神器和'parent.relativePath'點在錯誤的本地POM

Question

我有一個關於jenkins構建的問題。由於標題描述它是一個「不可解析的父POM for找不到神器和'parent.relativePath'指向錯誤的本地POM」問題，經常在stackoverflow上找到，但我還沒有找到匹配的問題。因此，這裏是我的問題描述

我的項目結構如下：

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

在我的本地機器（窗口）我可以建立我的項目/有：

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

沒有錯誤的，即使是一個空的存儲庫。

但jenkins（linux）無法做到這一點。

那麼這裏就是在我父POM

<?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> 

和模塊POM的一個例子

<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> 

正如我已經嘗試過其他項提及，但它沒有改變結果。爲什麼它應該指向存儲庫，父母從未去過。 那麼有人有一個建議，我做錯了什麼？

如這裏問是的MVN幫助輸出：有效-POM：

Answer 1

的<artifactId>爲你的父母在你的例子模塊POM是root-project。

您父母的pom中的<artifactId>是prject。在詹金斯輸出中，似乎該工件的名稱正在解析爲rootproject。嘗試設置父母的pom <artifactId>到root-project（注意額外的' - '）。

我不確定這是如何構建在您的機器上的。您可以在運行jenkins的計算機和機器上發佈運行mvn help:effective-pom的輸出嗎？

值得一提的是，您可以啓用調試輸出的-X標誌來查看Maven可能試圖採取的操作。我發現這在調試我的Maven項目的配置時很有用。
