Nexus 文件上传指北

上传方式有两种

1. 使用maven deploy插件上传
2. 使用API接口上传

---

1.maven deploy：deploy-file方式

上传命令：

mvn deploy:deploy-file 
    -DgroupId=com.somecompany 
    -DartifactId=project 
    -Dversion=1.0.0 
    -DgeneratePom=true 
    -Dpackaging=jar 
    -DrepositoryId=RepoName
    -Durl=http://localhost:8081/repository/maven-releases 
    -Dfile=target/project-1.0.0.jar

同时还需要配置好用户名密码：

在/usr/local/maven/conf/settings.xml中添加：

<server>
    <id>RepoName</id>
    <username>xxx</username>
    <password>xxx</password>
</server>

2.使用API方式之CURL命令实现

curl -v 
    -F hasPom=false  
    -F r=releases  // 仓库名
    -F e=jar       //文件类型
    -F g=com.***.devops // group id
    -F a=helloworld3    //artifact id
    -F v=0.0.5          // version
    -F p=jar            
    -F file=@/someworkspace/nexus-devops-testhelloworld/helloworld-10.7.2.1.jar  
    -u user:passwprd 
http://nexus.***.cn/service/local/artifact/maven/content

3.使用API方式之python实现
