Answer 1

setting.xml配置文件把拉包仓库地址http://maven.aliyun.com/nexus/content/groups/public/换成https://maven.aliyun.com/repository/central即：

              <repository>
                  <id>central</id>
                  <name>Maven2 Central Repository</name>
                  <layout>default</layout>
                  <url>https://maven.aliyun.com/repository/central</url>               
             </repository>
