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

<parent>

请帮助我！

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。

此外：

relativePath看起来很奇怪。而不是'..'
```
<relativePath>..</relativePath>
```
尝试'../'代替：
```
<relativePath>../</relativePath>
```
如果您使用标准版面，也可以删除relativePath。这是我一直以来所做的，在命令行上我也可以构建父（以及所有模块）或只有一个模块。
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。

Answer 2

我参加聚会可能有点晚了，但是我在TOPdesk为我的论文项目写了junitcategorizer。早期版本的确使用了公司内部的Parent POM。因此，您的问题是由于父POM无法解决而引起的，因为它对外界不可用。

您可以：

删除<parent>块，但随后必须自己配置Surefire，Compiler和其他插件
（仅适用于此特定情况！）通过设置将其更改为指向我们的开源父POM。

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

Answer 3

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。

Answer 4

java版本中存在冲突。在maven中使用1.8后已解决。

Answer 5

因此，在我的情况下，尝试了上述所有选项后，我意识到它是VPN（公司防火墙）。一旦连接并运行cmd：clean install spring-boot：run。问题已解决。步骤1：检查Maven配置是否正确。步骤2：检查settings.xml是否正确映射。步骤3：验证您是否在任何防火墙后面，然后相应地映射您的回购网址。步骤4：运行全新安装spring-boot：run 步骤5：问题已解决。

         ` Adding the following to pom.xml will resolve the issue.      <pluginRepositories>
        <pluginRepository>
            <id>central</id>
            <name>Central Repository</name>
