Jenkins配置構建Maven項目並打包Docker鏡像推送至私倉

本文轉載自查看原文 2020-10-30 11:06 1290 Jenkins/ Maven/ Docker

備注

Jenkins構建Maven項目需要安裝Maven插件,安裝后Maven插件默認配置文件路徑為:/root/jenkins/tools/hudson.tasks.Maven_MavenInstallation/maven3.6.3/conf/settings.xml。

需要將本地maven settings.xml配置信息配置至該settings.xml中，否則Jenkins構建項目因為無法下載相關jar包而失敗

一、配置構建任務

新增任務，選擇“構建一個maven項目”

二、配置構建任務

2.1 源碼管理

配置項目git地址，認證可手動添加，為git的登錄賬戶和密碼，指定分支填寫需要構建的分支

2.2 Pre Steps

可執行Jenkins構建前的腳本,可增加更多的bulid step，例如:

2.3 Build

設置POM文件以及執行的相關安裝命令等，如果需要跳過Maven的test，則增加-Dmaven.test.skip=true配置

2.4 Post Steps

項目構建完成后，執行的腳本，當前打包鏡像以及推送私倉主要通過該step完成。

三、網關通過Jenkins打包發布鏡像腳本
