我搭建了一个spring-boot2.0的maven项目，多个模块。项目能运行，但是在mvn install时报错：
[ERROR] COMPILATION ERROR :

自己百度，也到各种群里问过，但是还是不能解决，特来求教wendal大神，虽然不是nutz相关，但是大神是善良的对吗？
下面附上说明：
1.项目叫pmp，里面有一个主pom，pmp下有两个子模块，admin和common，admin依赖common，当admin中不import common中
的类时，admin 的mvn install正常，import后就报错如上。但是admin能用main方法正常启动且无报错。
-----初步怀疑是admin的pom里面的build不对，下面贴上
2. admin的pom.xml
