拿到制品的核心就是定位制品，仓库URL+GroupID+ArtifactId+Version就可以定位一个制品
使用Jenkins插件发布制品
发布其实就是下载制品，然后将制品发送到目标主机，最后通过脚本或者指令启动程序。
下面是下载制品的示例：
curl http://192.168.1.200:8081/repository/devops-maven/com/example/demo/1.1.10/demo-1.1.10.jar -o app.jar -uadmin:admin123现在我要用插件列出这个制品不同的版本，并且赋值给变量artifatUrl
安装Maven Artifact ChoiceListProvider (Nexus)插件， 可以使用该插件列出包列表。
后面又上传了不同版本的制品，这里可以列出不同的版本，并且对其排序。
这个时候用户就可以去选择了，用户选择制品后， 拿到地址点击构建就可以拿到包的地址了。此时可以想象，Jenkins下载这个包， 然后通过salt、ansible进行发布部署。
String artifactURL = "${env.artifactUrl}".toString()pipeline {agent anystages {stage('Hello') {steps {println("The artifact url is: ${artifactURL}")sh "wget ${artifactURL} && ls"}}}
}
