自己百度弄了一天了，求大神帮忙！

Question

Failure to transfer org.codehaus.plexus:plexus:pom:1.0.4 from http://repo.maven.apache.org/maven2 was cached in the local
repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced. Original
error: Could not transfer artifact org.codehaus.plexus:plexus:pom:1.0.4 from/to central (http://repo.maven.apache.org/maven2):
connection timed out to http://repo.maven.apache.org/maven2/org/codehaus/plexus/plexus/1.0.4/plexus-1.0.4.pom

百度了很多会了！一直接解决不了这个问题！我创建的Maven项目的pom.xml老是报上面的异常！求给我这新手指点指点！

Answer 1

错误信息提示了2个问题：
1.maven缓存了codehaus，到maven本地库找到对应的文件夹删除，重新maven install。

2.maven远程仓库连接超时
