在使用maven过程中出现的问题（1）——运行mvn compile报错

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

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
org.apache.maven.plugins maven-resources-plugin 2.6

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
