Jenkins插件小贴士 (五) About Artifact 2
历史问题
上一篇<<Jenkins插件小贴士 (四) About Artifact>>
介绍了如何将构建完的二进制物(JAR/WAR)上传到Maven私库,但还是有可以改进的地方.
1 | environment { |
比如:
GROUP ID和ARTIFACT ID这些都是硬编码的
每次发布新版本都需要修改Jenkinsfile
上传到Maven私服的JAR需要多一个POM文件来描述才能顺利被客户端的Maven识别和下载.
如果不是通过mvn deploy的方式是不会自动产生pom文件的,但采用mvn deploy的方式又需要在maven setting暴露私库账号和密码.
新思路
参考了 github上的Jenkins集成Nexus demo项目, 有了新的想法:
- 利用Jenkins ci 读取项目里的POM.xml文件
- 代码生成对应的xx.pom文件
- 上传到私库
前置条件
安装插件 ：Pipeline Utility Steps
通过插件Pipeline Utility Steps
可以很方便地使用readMavenPom命令读取pom文件设置Jenkins权限 scriptApproval : 允许Approval
Jenkins执行groovy脚本的时候会出错,是因为权限问题,需要设置对应的权限才能让脚本顺利写文件到硬盘里.具体实现
- 定义POM文件所需变量

权限问题
执行job的时候会遇到错误: Scripts not permitted to use method xxx
这个时候需要管理员去 Jenkins >> ScriptApproval 去approval对应的脚本.
End
- 此过程需要不断调试直至Job顺利完成
- 自此就可以把项目把maven构建和上传私库2个动作分开,降低开发人员的入手难度.
