谷粒商城项目中在idea中聚合服务的过程中遇到maven问题。
解决：在更改maven路径，镜像地址，jdk版本后，发现并不只是maven的配置问题（在gulimall-member中也显示root标识），于是删除错误的分支重新创建，并更新其他分支。中间零零碎碎也做了一些重新检查pom文件的操作，个人觉得没有更改什么，很玄学的解决了
注：maven配置检查idea版本为2019，maven版本为3.3.3，确认版本兼容，其次检查conf/setting.xml中的具体配置。

maven检查配置参考：

1.Maven 的本地仓库放在其他盘符下。
注：maven解压路径与本地仓库路径都默认无中文和空格。
<!-- localRepository
| The path to the local repository maven will use to store artifacts.
|
| Default: ${user.home}/.m2/repository
<localRepository>/path/to/local/repo</localRepository>
-->
<localRepository>D:\maven-repository</localRepository>2.配置阿里镜像，注释原有配置，将镜像配置进mirrors 标签的内部。
<!--
<mirror>
<id>mirrorId</id>
<mirrorOf>central</mirrorOf>
<name>*</name>
<url>http://192.168.1.146:8081/nexus/content/groups/yes-tech/</url>
</mirror>-->
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
</mirror>3.maven默认jdk版本为1.5，此处改为1.8，在profiles中加入下放代码。文章来源：https://www.toymoban.com/news/detail-772775.html
