    Reason: Failed to copy file for artifact[com.taobao.lifeuser:lifeuser-core:jar:1.0.0-SNAPSHOT:compile]

 

    错误原因：需要操作本次仓库中lifeuser-core.jar这个包，而在本地的workspace已经有一个lifeuser-core工程,此工程中也有一份lifeuser-core.jar包，导致出错.

 

    解决方案：先将lifeuser-core这工程关掉，然后再去maven war:inplace（install、package），就不会有问题了。
