問題
jenkins部署專案maven編譯時報錯

分析
相同mvn命令，本地編譯異常，通過jenkins編譯報錯，定位是使用者許可權問題
在shell中新增whoami列印jenkins用的是jenkins使用者
jenkins是通過yum安裝時自動建立的系統使用者（沒有目錄，沒有配置檔案），無法通過su命令切換
要麼改成root或其他使用者，要麼將mvn相關目錄所有者改為jenkins（實測無效，可能時因為jenkins不是普通使用者，無配置)
解決辦法
將jenkins預設使用者改為root或其他
//修改使用者為root或其他
vim /etc/sysconfig/jenkins
//重啟jenkins systemctl restart jenkins
修改後編譯成功！
