为什么Maven抛出的错误像‘必须是’pom‘而不是’jar‘？

我需要修正下面的maven错误。
当我跑步时：
mvn清洁安装
我得到：
[ERROR] The build could not read 1 project -> [Help 1]
org.apache.maven.project.ProjectBuildingException: Some problems were encountered while processing the POMs:
[ERROR] Invalid packaging for parent POM org.springframework.boot:spring-boot-starter-parent:2.0.5.RELEASE, must be "pom" but is "jar" @ org.springframework.boot:spring-boot-starter-parent:2.0.5.RELEASE
[ERROR] 'packaging' with value 'jar' is invalid. Aggregator projects require 'pom' as packaging. @ line 3, column 102这是我的包层次结构：
.

└── pom.xml下面是我的词根：

缺少应用程序文件夹中的pom.xml：
<parent>
<groupId>com.tim.project</groupId>
<artifactId>myservice</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>Stack Overflow用户

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.5.RELEASE</version>
<relativePath/>
</parent>尝试删除<relativePath/>并将其替换为<type>pom</type>
编辑
我有一些非常相似的东西:根pom
<groupId>org.company</groupId>
<artifactId>my-parent</artifactId>
<version>1.1</version>
<packaging>pom</packaging>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.1.8.RELEASE</version>
</parent>然后，应用程序：
<artifactId>my-spring-app</artifactId>
<packaging>jar</packaging>
<parent>
<groupId>org.company</groupId>
<artifactId>my-parent</artifactId>
<version>1.1</version><!-- version can be different of course-->
