解决Eclipse出现的Failure to transfer ... jar问题

问题描述：Failure to transfer com.thoughtworks.xstream:xstream:jar:1.3.1 fromhttp://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.
原因：maven版本问题，eclipse自带的是maven2

解决：

1.官网下载新的maven安装文件，maven3

2.清除repository下的jar包，重新下载jar包解决Eclipse出现的Failure to transfer com.thoughtworks.xstream:xstream:jar问题

 

原来如此
