#Maven 测试仓库命令，下载jar包,测试一般会报错，说没有权限
mvn dependency:get -DremoteRepositories=http://47.98.114.63:14006/repository/maven-third/ -DgroupId=com.taobao -DartifactId=taobao-sdk-java-auto -Dversion=20190804

sonatype/nexus3安装

  1. 创建挂载目录mkdir -p v-nexus/data并修改目录权限chown -R 200 v-nexus/data

  2. 创建部署脚本

    # 默认用户名admin/admin123
    version: '3.2'

    services:
      nexus:
        restart: always
        image: sonatype/nexus3
        ports:  #自定义端口
          - target: 8081
            published: 18081   #只有worker能访问该端口
            protocol: tcp
            mode: host  #版本要求3.2
        volumes:
          - "/dockerdata/v-nexus/data:/nexus-data"
        deploy:
          replicas: 1
          restart_policy:
            condition: on-failure
          placement:
            constraints: [node.hostname == lfadmin]

  3. 测试访问http://192.168.1.213:18081/然后输入admin和admin123进行登陆即可

配置yum代理

远程原remote url: http://maven.aliyun.com/nexus/content/groups/public

新建一个type:yum(proxy)

在新建一个组yum(group),添加刚刚的代理地址,同理，可以添加elpe,docker等其他仓库代理

复制生成的地址http://192.168.1.230:18081/repository/yum-public/配置在`nexus.repo`

执行vim /etc/yum.repos.d/nexus.repo

yum clean all

rm -rf /etc/yum.repos.d/C*

注意

epel源需要单独配置，直接用public不识别

执行vim /etc/yum.repos.d/nexus-epel.repo

win10下maven安装

  1. 下载apache-maven-3.5.4-bin.zip然后解压

  2. 添加环境变量,新建系统环境变量Maven_HOME值为解压路径，编辑path环境变量添加%Maven_HOME%\bin

  3. 命令窗口测试mvn -v，只支持cmd

  4. 修改apache-maven-3.5.4\conf\settings.xml文件

    <!--jar本地缓存地址-->
    <localRepository>D:\MavenRepository</localRepository>

  5. 完整的setting.xml设置

    		</snapshotRepository>
    	</distributionManagement>
        ...
    </project>

  7. 编译在cmd执行mvn install发布上传jar执行mvn deploy，可以到nexus地址进行检查

  8. 使用私库下载和上传是一样的

nexus3 配置阿里云代理仓库

  1. 点击Create Repository->maven2(proxy)
  2. 添加名字aliyun-proxy设置阿里云url地址http://maven.aliyun.com/nexus/content/groups/public
  3. 设置阿里云优先级，在maven-public里面的group把刚刚创建的添加过去并移到maven-central上面
  4. 设置允许发布release,在maven-release的hosted里面选择allow redeploy

创建第三方仓库

  1. create repository->maven2(hosted)

    name:3rd_part

    hosted:Allow redeploy

  2. 添加srd_part到maven_public

  3. 如果没有groupId最好统一为com.3rdPart标注为第三方包

发布上传jar包到nexus

配置用户和角色

  1. 创建roles:

    id: nx-deploy

    prlvlleges: nx-repository-view-*-*-*

  2. 创建用户：

    ID: develop

    roles: nx-deploy

        </repository>
    </repositories>

问题

  1. 下载了找不到包，解决，删除项目重新导入，重新maven依赖
  2. 刚上传或添加了新的jar到私库，无法下载，解决，删除本地仓库的该包目录
  3. 注意powershell执行命令时需要在等号后面加双引号，不然改用cmd
