Maven, Inherit pom module
问题
我正在编写一个项目，但在编译项目时遇到了问题。在我根据pom文件中显示的方式导入了必要的依赖后，我无法运行项目。
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

</project>
pom文件显示的错误如下：
项目构建错误：POM org.springframework.boot:universeBySali-web:1.3.6.RELEASE (C:\Users\User\Desktop\Materiale\Desktop\Java Projects\universeBySali\universeBySali-web\pom.xml) 的'parent.relativePath'指向 com.sali:universeBySali 而不是 org.springframework.boot:spring-boot-starter-parent，请验证您的项目结构
该pom文件具有如下所示的父pom：

</project>
有人能告诉我我做错了什么吗？谢谢

The error that it shows on the pom file is as follows:
Project build error: 'parent.relativePath' of POM org.springframework.boot:universeBySali-web:1.3.6.RELEASE (C:\Users\User\Desktop\Materiale\Desktop\Java Projects\universeBySali\universeBySali-web\pom.xml) points at com.sali:universeBySali instead of org.springframework.boot:spring-boot-starter-parent, please verify your project structure
This pom file has a parent pom as shown below:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">

Can somebody tell me what I am doing wrong?? Thanks

默认情况下，Maven假定父项目具有以下relativePath路径：../pom.xml。
Maven将尝试匹配groupId/artifactId/version，如果失败则会发出警告并使用“外部”父项目。
为确保Maven不会在多模块中尝试解析父项目，您应该在父项目中添加<relativePath/>。
英文:
By default Maven assumes the parent has the following relativePath: ../pom.xml.
Maven will try to match match the groupId/artifactId/version, if it doesn't succeed a warning is thrown and an "external" parent is used.
To ensure Maven won't try to solve the parent as part of your multimodule, you should add <relativePath/> to the parent.
