Jenkins项目

• serviceName: 服务名称
• buildShell: 构建命令
• targetHosts: 发布目标主机
• user: 执行用户
• targetDir: 发布目标主机的工作目录

Jenkinsfile

将build完成的二进制文件、static、service.sh生产压缩包。 移动到发布目录，发布，解压包，启动服务。

String buildShell = "${env.buildShell}"
String targetHosts = "${env.targetHosts}"
String targetDir = "${env.targetDir}"
String serviceName = "${env.serviceName}"
String user = "${env.user}"
