执行：不可解析的父 POM 和“父级路径”指向错误的本地 POM

Question

我正在使用maven 3运行该应用程序，但我收到以下错误：

我有以下父pom文件（其中的一部分）：

我有以下子模块pom文件：

 <modelVersion>4.0.0</modelVersion>

<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>

我试着在父pom文件中注释下面的部分（我不知道这样做是否正确），然后这个错误就消失了，构建也因这个错误而失败。

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

请帮帮我！

谢谢

Answer 1

java版本中存在冲突。在对maven使用1.8后解决。

Answer 2

我可能有点晚了，但是我在TOPdesk为我的论文项目写了一部分。早期版本确实使用了公司内部的父POM。所以你的问题是由父POM无法解决引起的，因为它对外界来说是不可用的。

您可以:

• 删除

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

Answer 3

maven多模块项目的正常布局是:

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

检查是否使用此布局。

此外：

>

relativePath看起来很奇怪。而不是“..”

<relativePath>..</relativePath>

“尝试”../'代替:

<relativePath>../</relativePath>

如果使用标准布局，还可以删除relativePath。这是我一直在做的，在命令行上，我还可以构建父模块（和所有模块），或者只构建单个模块。

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< code > JUnit categorizer . cut detection 不是文件夹的名称，请相应地更改它。

希望有所帮助。

编辑看看别的帖子，我在那里回答的。
