记一次mvn clean install 报package com.rockysaas.shopguide.common.config.threadpool does not exist

最近在导购项目中增加了两个模块，common,job. 原先的admin，web还有job引用了common包。其中common包的pom.xml如下

<?xml version="1.0" encoding="UTF-8"?>

admin的pom.xml引用到了common包

  <dependencies>
 。。。
        <dependency>
            <groupId>com.rockysaas.shopguide</groupId>
            <artifactId>common</artifactId>
        </dependency>
。。。
</dependencies>

admin项目引用了common里的变量

import com.rockysaas.shopguide.common.config.threadpool.ThreadPoolProperties;

@Component
@ConfigurationProperties(prefix = "task.threadpool.executor")
public class TaskThreadPoolProperties  extends ThreadPoolProperties {
}

但是整个项目mvn clean install -Dmaven.test.skip=true 时却报了

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project admin: Compilation failure: Compilation failure:

在idea中启动项目没问题也没报编译错误，而且我在job项目里引入common的变量后也有这个问题。经过几个小时的实验和测试，发现问题是在common的pom.xml里加上了

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

把这个去掉就一切正常。这个插件是启动springboot项目服务时用的，但common只是一个包，并不需要启动服务。看来对一些东西不是特别清楚时乱加就是会出各种问题。
