解决Plugin org.apache.maven.plugins:maven-archetype-plugin:RELEASE or one of its dependencies could not be resolved的问题
最近在学习JAvaWeb,在第一次使用IDEA(以前没用过)创建maven项目时,老是创建不成功,文件残缺,下面是错误提示。
[WARNING] Could not transfer metadata org.apache.maven.plugins:maven-archetype-plugin/maven-metadata.xml from/to central (https://repo.maven.apache.org/maven2): Received fatal alert: protocol_version

这个错误着实让我头疼,在网上找了大量的解决办法一直不奏效,最后自己慢慢摸索出来了一个解决办法,原理不是很明确,但是确实解决了我这个问题,所以记录下来与大家分享,希望能帮助有需要的人。
一、
首先打开maven解压目录下的conf文件夹里的setting.xml,在其中添加如下仓库位置和插件下载url(因为默认的是在国外,在这里我们改成阿里云的国内镜像)
<localRepository>E:apache-maven-3.6.0
epository</localRepository>
- 1
这个仓库路径是你自己选的,需要存在这个路径(我是直接在maven的解压文件夹里创建了一个repository)
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>

添加阿里云的国内镜像地址。
保存之后退出。
二、
在IDEA中依次按照路径file-setting找到maven配置选项(如下图),将如下两项修改:第一项修改为maven解压目录下的conf文件夹里的setting.xml,第二项会自动读取setting.xml文件里的仓库地址(如果未自动读取,检查下自己是否写错了),也可以手动更改。更改完成之后点击Apply-OK。
之后重启IDEA,新建maven项目,就可以发现上面的错误不见啦。
