搭建nexus服务器后，执行mvn出错解决办法

搭建nexus服务器，请参考：

http://www.blogjava.net/xiaomage234/archive/2012/11/22/391770.html

搭建完成后在setting.xml中配置镜像

	<mirrors>
		<mirror>
			<id>public</id>
			<mirrorOf>*</mirrorOf>
			<name>Public Repositories</name>
			<url>http://localhost:9088/maven/content/groups/public/</url>
		</mirror>
	</mirrors>

然后在mvn项目下执行mvn clean install命令出错：

Caused by: org.eclipse.aether.transfer.ArtifactNotFoundException: Failure to fin
d org.apache.maven.plugins:maven-clean-plugin:jar:2.5 in http://localhost:90
88/maven/content/groups/public/ was cached in the local repository, resolution w
ill not be reattempted until the update interval of public has elapsed or update
s are forced

解决办法：

1. 执行命令时加上-U

 mvn clean install -U

You need to delete all "_maven.repositories" files from your repository.呵呵引用下面文章的话
