maven - 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：

我有以下父 pom 文件（其中的一部分）：

</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>

    <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出现此错误。

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

请帮我！

谢谢

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。代替 '..'
```
<relativePath>..</relativePath>
```
尝试 '../' 代替：
```
<relativePath>../</relativePath>
```
relativePath如果您使用标准布局，您也可以删除。这就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）或只构建一个模块。
模块路径可能错误。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。

希望有帮助..

我参加聚会可能有点晚了，但我为我在 TOPdesk 的论文项目编写了 junitcategorizer。早期版本确实使用了公司内部的 Parent POM。因此，您的问题是由 Parent POM 无法解决引起的，因为它对外界不可用。

您可以：

删除<parent>块，但必须自己配置 Surefire、Compiler 和其他插件
（仅适用于这种特定情况！）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>

java版本有冲突。使用 1.8 for maven 后解决。

您可以尝试以下方式，

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

这样父 jar 将从存储库中获取。

所以就我而言，在尝试了上述所有选项之后，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。第1步：检查maven是否配置正确。第 2 步：检查 settings.xml 是否映射正确。第 3 步：验证您是否位于任何防火墙之后，然后相应地映射您的 repo url。第 4 步：运行全新安装 spring-boot：运行第 5 步：问题已解决。

添加以下内容pom.xml将解决该问题：

<pluginRepositories>
    <pluginRepository>
        <id>central</id>
        <name>Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>
        <layout>default</layout>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
        <releases>
            <updatePolicy>never</updatePolicy>
        </releases>
    </pluginRepository>
</pluginRepositories>

<repositories>
    <repository>
        <id>central</id>
        <name>Central Repository</name>
        <url>https://repo.maven.apache.org/maven2</url>

在 Windows 上使用 Maven 3.8.3，我通过显式指定父 pom.xml ( ) 的相对路径没有问题../pom.xml，即：

<parent>
    <groupId>org.example</groupId>
    <artifactId>example</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../pom.xml</relativePath>
</parent>

唯一让我失望的是误导性的文档。

引用Maven 源relativePath代码：

pom.xml检出中父文件的相对路径。默认值为../pom.xml。[...]

现在，虽然文档说明这../pom.xml应该是默认设置，但替换<relativePath>../pom.xml</relativePath>为具有<relativePath/>产生问题中报告的错误的效果。
