解决办法：
1、查看Jenkins容器

docker ps

2、进入jenkins容器

docker exec -it <容器> bash

3、安装vi

apt-get update
apt-get install vim

4、进入Maven配置文件夹

cd /var/jenkins_home/tools/hudson.tasks.Maven_MavenInstallation/Maven/conf

5、修改Maven配置文件

vi settings.xml

6、屏蔽以下配置

<mirror>
      <id>maven-default-http-blocker</id>
      <mirrorOf>external:http:*</mirrorOf>
      <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
      <url>http://0.0.0.0/</url>
      <blocked>true</blocked>
    </mirror>

7、增加以下配置

<mirrors>
       <mirror>
            <id>nexus-aliyun</id>
            <mirrorOf>*,!jeecg,!jeecg-snapshots,!getui-nexus</mirrorOf>
            <name>Nexus aliyun</name>
            <url>http://maven.aliyun.com/nexus/content/groups/public</url>
        </mirror> 
 </mirrors>
