eclipse中的Maven错误（pom.xml）：无法转移org.apache.maven.plugins：maven-surefire-plugin：pom：2.12.4

我想使用Maven制作Web项目自动导入我需要的所有库，所以我选择maven-archetype-webpp

I wanna make web project using the Maven to import automatically all libraries that I need, so I chose "maven-archetype-webpp"

之后我在pom.xml文件上出现此错误：

after that I got this error on pom.xml file :

Description Resource Path Location Type Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 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.apache.maven.plugins:maven-surefire-plugin:pom:2.12.4 from/to central (http://repo.maven.apache.org/maven2): The operation was cancelled. pom.xml /SpringTuto line 1 Maven Configuration Problem

我已经更新了我的Maven项目但是没有结果!!
