Failure to transfer org.apache.maven.plugins:maven-surefire-plugin:pom:2.18.1 from .....

maven默认目录：C:\Users\用户名\.m2\repository\org\apache\maven

解决办法:
1.删除所有以maven目录下\plugins\maven-surefire-plugin\2.18.1  lastUpdated结尾的文件
2.右键点击project -> Maven - Update Dependencies（Update Project...）

如果点击更新后发现

~\.m2\repository\org\apache\maven\plugins\maven-surefire-plugin\2.18.1

下还是没有maven-surefire-plugin-2.18.1.jar
去http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-surefire-plugin/2.18.1/
下载

maven-surefire-plugin-2.18.1.jar maven-surefire-plugin-2.18.1.jar.sha1 maven-surefire-plugin-2.18.1.pom maven-surefire-plugin-2.18.1.pom.sha1
