我正在使用maven 3来运行应用程序，但是我收到以下错误：

我有以下父pom文件（部分）：

<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>com.topdesk</groupId>
<artifactId>tis-parent</artifactId>
<version>3.4</version>
</parent>

</properties>

<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文件中评论下面的部分（我不知道它是否正确），然后这个错误消失了，构建失败并出现this错误。

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

请帮我！

谢谢

答案

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。代替 '..' <relativePath>..</relativePath> 试试'../'代替： <relativePath>../</relativePath> 如果使用标准布局，也可以删除relativePath。这是我经常做的，在命令行上我也可以构建父（和所​​有模块）或只有一个模块。
  2. 模块路径可能是错误的。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，而不是工件标识符。如果junitcategorizer.cutdetection不是文件夹的名称，则相应地更改它。

希望有所帮助..

编辑看看另一篇文章，我在那里回答。

另一答案

您可以尝试以下方式，

 <parent>
    <groupId></groupId>
    <artifactId></artifactId>
    <version></version>
  </parent>

这样父jar就会从存储库中获取。

另一答案

java版本存在冲突。使用1.8 for maven后解决。

另一答案

所以在我的情况下，在尝试了以上所有选项后，我意识到它是VPN（公司防火墙）.once已连接并运行cmd：clean install spring-boot：run。问题已解决。第1步：检查maven是否配置正确。第2步：检查settings.xml是否正确映射。第3步：验证您是否在任何防火墙后面，然后相应地映射您的repo URL。第4步：运行clean install spring-boot：运行步骤5：解决问题。
