Maven异常：Could not find artifact

用Maven build（"clean tomcat7:run" ）  Maven聚合工程时，出现了一下问题:

[INFO] Scanning for projects...

注意查看这句:

 

Could not find artifact com.easybuy:easybuy-parent:pom:0.0.1-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 3, column 11 ->  
 

　　

原因是本地仓库缺少了easybuy-parent:pom:0.0.1-SNAPSHOT, 原来是忘记了将父工程打包到本地仓库 ，运行聚合工程前记得先将依赖的工程都先Maven install到本地仓库，否则也会出现以上问题

用Maven install 对父工程安装到本地仓库
