eclipse maven项目错误：Failure to transfer org.codehaus.plexus:plexus-interpolation:jar:1.15 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-interpolation:jar:1.15 from/to central (http://repo.maven.apache.org/maven2): The operation was cancelled.pom.xml

 

解决办法：删除掉下载失败的jar

find ~/.m2 -name "*.lastUpdated" -exec grep -q "Could not transfer" {} \; -print -exec rm {} \;​

windows下：

1、cd %userprofile%\.m2\repository 

2、for /r %i in (*.lastUpdated) do del %i​

 

​然后在项目中右键选择 Maven->UpdateDependencies.

3、或者右键：Maven -> Disable maven nature

4、然后右键：​Configure > Convert to maven Project
