使用Nexus作为二进制制品管理仓库，二进制制品的上传主要可以通过三种方式来进行，结合Apache Maven Deploy Plugin进行操作、通过Nexus提供的UI界面进行或者通过Nexus提供的API进行操作，这篇文章对二进制制品上传至Nexus的方法进行介绍。
使用docker镜像方式启动Nexus的3.16.1版本的服务。docker-compose.yml信息如下所示：
version: '2' services: # Repository service: Nexus nexus: image: sonatype/nexus3:3.16.1 ports: - "32004:8081" volumes: - /home/local/nexus/data/:/nexus-data environment: - JAVA_MAX_MEN=512m - JAVA_MIN_MEN=128m restart: "no"Apache Maven提供了相关的插件对部署至远方仓库进行操作，这里以一个spring boot生成的jar文件为例，介绍了使用Apache Maven Deploy Plugin进行二进制制品上传的方法以及相关注意事项，详细请参看如下文章：

使用–upload-file进行上传： 示例：curl -v -u admin:admin123 --upload-file target/springbootdemo-0.0.5-SNAPSHOT.jar http://192.168.163.141:32004/repository/mvnhosted/com/liumiaocn/springbootdemo/0.0.5-SNAPSHOT/springbootdemo-0.0.5-SNAPSHOT.jar
执行示例日志
