Maven:不可解析的父 POM 和 'parent.relativePath' 指向错误的本地 POM

Question

我正在使用 maven 3 运行应用程序，但出现以下错误:

[ERROR] The build could not read 1 project -> [Help 1]
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:

我有以下父 pom 文件(其中的一部分):

<modelVersion>4.0.0</modelVersion>

</properties>

<prerequisites>

</prerequisites>

我有以下子模块 pom 文件:

 <modelVersion>4.0.0</modelVersion>
 <parent>
<artifactId>junitcategorizer</artifactId>
<groupId>com.topdesk.test.junitcategorizer</groupId>
<version>0.0.1-SNAPSHOT</version>
<relativePath>..</relativePath>
</parent>
<artifactId>junitcategorizer.cutdetection</artifactId>
<name>Analysis of parameters for the CUT detection algorithm</name>
<description>Analysis of parameters for the CUT detection algorithm</description>
<dependencies>
<dependency>

    <artifactId>junitcategorizer.instrument</artifactId>
    <version>0.0.1-SNAPSHOT</version>
</dependency>
</dependencies>
</project>

我尝试在父 pom 文件中注释以下部分(我不知道这样做是否正确)，然后此错误消失并且构建失败并显示 this错误。

<parent>
<groupId>com.topdesk</groupId>
<artifactId>tis-parent</artifactId>
<version>3.4</version>
</parent>

请帮帮我!

谢谢

Answer 1

maven 多模块项目的正常布局是:

parent
├── pom.xml
├── module
    ├── pom.xml

检查您是否使用此布局。

另外:

1. relativePath 看起来很奇怪。而不是'..'

   <relativePath>..</relativePath>
   

   改用“../”:

   <relativePath>../</relativePath>
   

   如果您使用标准布局，您也可以删除 relativePath。这是我一直在做的事情，在命令行上我也可以构建父模块(和所有模块)或只构建单个模块。

2. 模块路径可能有误。在父级中，您将模块定义为:

   <module>junitcategorizer.cutdetection</module>
   

   您必须指定子模块的文件夹名称，而不是 Artifact 标识符。如果 junitcategorizer.cutdetection 不是文件夹的名称，则相应地更改它。

希望对您有所帮助..
