Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from http://uk.maven.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of UK has elapsed or updates are forced. Original error: Could not transfer artifact org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from/to UK (http://uk.maven.org/maven2): The operation was cancelled.

一般情况下可能是文件格式有问题,将正确的文件内容替换掉错误的文件内容，不断地尝试，直到文件不报错,当然也有可能是下面的原因:下面是2.7.1版本的方法,其他类似)

1.找到maven库目录，进入：~\.m2\repository\org\apache\maven\plugins\maven-surefire-plugin\2.7.1

2.若2.7.1目录下只有，"maven-surefire-plugin-2.7.1.pom.lastUpdated" 则需要到http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-surefire-plugin/2.7.1/，把里面的文件下载下来放到2.7.1

3.删除2.7.1下的maven-surefire-plugin-2.7.1.pom.lastUpdated文件。

4.项目右键-->maven-->Update Dependencies
