第一次用maven创建项目，运行mvn compile报错
[ERROR] Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org. apache.maven.plugins:maven-resources-plugin:jar:2.6: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from/to central (https: //repo.maven.apache.org/maven2): Received fatal alert: protocol_version -> [Help 1] [ERROR] Plugin org.apache.maven.plugins:maven-resources-plugin:2.6 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org. apache.maven.plugins:maven-resources-plugin:jar:2.6: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.6 from/to central (https: //repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven. apache.org -> [Help 1]开始真的是一头雾水，在网上查找解决办法， 1、有的说缺少依赖，直接在pom文件中添加依赖添加链接描述 <dependency> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-resources-plugin</artifactId> <version>2.6</version> </dependency>
2、有的说原因是maven的中央仓库没法访问 解决方法是修改conf/settings.xml,设mirror为http://mirrors.ibiblio.org/pub/mirrors/maven2
… 我的解决办法就是卸载了原来的maven3.5.2，重新下载解压了一个maven3.2.2------------可能是版本的问题，也可能是当时配置有稍许问题…???
其他见参考：maven compile问题解决
使用Maven命令创建项目
