阿里maven仓库地址换了，使用老地址有可能使java项目出现各类问题

使用maven的java项目编译和发布错误，有些是maven仓库引发的，java

例如dependencies could not be resolved错误，这个错误的提示有可能象这样：
node

[ERROR] Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failure to find org.apache.maven.plugins:maven-compiler-plugin:jar:3.1 in http://maven.aliyun.com/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus-aliyun has elapsed or updates are forcedspring

有同窗遇到这个问题，他这个项目的maven配置文件为：apache

......maven

<localRepository>D:\workspace-4.7\repository</localRepository>ide

......gradle

<mirrors>google

<mirror>阿里云

<id>nexus-aliyun</id>url

<mirrorOf>central</mirrorOf>

<name>Nexus aliyun</name>

<url>http://maven.aliyun.com/nexus/content/groups/public</url>

</mirror>

......

实际上http://maven.aliyun.com/nexus/content/groups/public已是老地址了，老地址有不可预料的各类问题，须要改成新地址：

......

<id>aliyunmaven</id>

<name>阿里云公共仓库</name>

<url>https://maven.aliyun.com/repository/public</url>

</mirror>

......

阿里云的新地址汇总以下：

仓库名称	阿里云仓库地址	阿里云仓库地址(老版)	源地址
central	https://maven.aliyun.com/repository/central	https://maven.aliyun.com/nexus/content/repositories/central	https://repo1.maven.org/maven2/
jcenter	https://maven.aliyun.com/repository/public	https://maven.aliyun.com/nexus/content/repositories/jcenter	http://jcenter.bintray.com/
public	https://maven.aliyun.com/repository/public	https://maven.aliyun.com/nexus/content/groups/public	central仓和jcenter仓的聚合仓
