Maven打包错误：找不到artifact com.springstudy:common-service:jar:0.0.1-SNAPSHOT //////?

Question

微服务项目出现Failed to execute goal on project sms-service: Could not resolve dependencies for project com.springstudy:sms-service:jar:0.0.1-SNAPSHOT:Could not find artifact com.springstudy:common-service:jar:0.0.1-SNAPSHOT->[Help 1]问题

在进行项目构建时，因为这是一个多层依赖的项目，因为会出现父模块打包方式必须为pom而非jar的错误，所以我将父模块、basic、repo、comm的打包方式设置为pom，之后就出现此问题，猜测是多层依赖下的打包方式导致的仓库查询问题。
product--->common--->repository--->base--->父模块
父模块pom

Answer 1

1/n 一般来说，只需要将父模块打包成pom，其他模块应该打包成jar
2/n 报错提示：sms-service依赖common-service，但是common-server未找到，
解决方案：
调整common-service pom.xml

    <parent>
        <artifactId>shop001</artifactId> <!--- parent的artifactId应该是写错了 --->
        <groupId>com.springstudy</groupId>
        <version>0.0.1-SNAPSHOT</version><relativePath/>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <packaging>jar</packaging> <!--- 改成jar --->

    <artifactId>common-service</artifactId>

3/n 其他的问题继续参照 2/n 的调整来解决。
