经测试发现,是(D:\Java\apache-maven-3.8.3\conf\settings.xml)进行了如下配置导致的
<mirror>
<id>aliyunmaven</id>
<mirrorOf>*</mirrorOf>
<name>阿里云公共仓库</name>
<url>https://maven.aliyun.com/repository/public</url>
</mirror>
或者下面这种,等等 ...
<!--阿里云镜像网站配置-->
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>central</mirrorOf>
<name>Nexus aliyun</name>
<url>http://maven.aliyun.com/nexus/content/groups/public</url>
<blocked>true</blocked>
</mirror>
删去上面的配置后,报错内容如下

这次报错是和代理有关
<proxy>
<id>optional</id>
<active>true</active>
<protocol>http</protocol>
<username>proxyuser</username>
<password>proxypass</password>
<host>proxy.host.net</host>
<port>80</port>
<nonProxyHosts>local.net|some.host.com</nonProxyHosts>
</proxy>
删去这部分配置后,即可恢复
