maven的pom报plugins却是的解决方法.

引用

Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.7.1 from http://repo1.maven.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

碰到一个类似以上的错误.
原因是maven的plugin并未下载到本地.

如果你查看

引用

~\.m2\repository\org\apache\maven\plugins\maven-surefire-plugin\2.7.1

的话,会发现里面只有一个

maven-surefire-plugin-2.7.1.pom.lastUpdated

的文件.
而并没有maven-surefire-plugin-2.7.1.jar

解决办法:
1.删除maven-surefire-plugin-2.7.1.pom.lastUpdated文件
2.右键点击project -> Maven - Update Dependencies

如果点击更新后发现

~\.m2\repository\org\apache\maven\plugins\maven-surefire-plugin\2.7.1

下还是没有maven-surefire-plugin-2.7.1.jar
去http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-surefire-plugin/2.7.1/
下载

maven-surefire-plugin-2.7.1.jar
maven-surefire-plugin-2.7.1.jar.sha1
maven-surefire-plugin-2.7.1.pom
maven-surefire-plugin-2.7.1.pom.sha1

包再重复步骤2.
