问题：[WARNING] Unrecognised tag: 'snapshotPolicy' (position: START_TAG seen ...</layout>\n <snapshotPolicy>... @286:27) @ D:\maven-3.6.1\bin\..\conf\settings.xml,line 286,column 27
出错位置：
<profile> id>jdk-1.7</> activation> jdk>1.7> repositoriesrepository> >jdk17name>Repository for JDK 1.7 buildsurl>http://www.myhost.com/maven/jdk17layout>default> <snapshotPolicy>always</snapshotPolicy> > >
解决方法，将该段替换为：
>nexus> activeByDefault>true> >Nexus>http://172.16.1.79:8082/repository/maven-public/> releases> enabledupdatePolicy>alwayssnapshots>daily>
不要问我为什么，我也不知道。。。
