Ubuntu 版本的 Jenkins 安裝 Java 11 Graalvm 筆記

最近自己的 一些 project, 剛好要用java11 才能compile, 但是用Jenkins內建安裝只能到Java9

,索性就安裝Graalvm,

發現問題

springboot 要打包docker 就發生以下的錯誤

/var/lib/jenkins/workspace/BZK
Removing network bzk_default
Network bzk_default not found.
Error: No such image: net.bzk/bzkflow
[Gradle] - Launching build.

ubutu安裝 graalvm

1. 先去 官方最新版 複製最新的版本下載
2. 到 ubuntu console :

cd /usr/lib/jvm/

sudo wget https://github.com/graalvm/graalvm-ce-builds/releases/download/vm-20.1.0/graalvm-ce-java11-linux-amd64-20.1.0.tar.gz

NOTE : 記得連結可以換最新版本

3. 解壓至此

tar -xvzf graalvm-ce-java11-linux-amd64-20.1.0.tar.gz

Jenkins 設定JDK

1. 先到 Global Tool Configuration
   
2. 點開 JDK... 選項
3. 新增JDK,並輸入內容

名稱 : {自行設定 for ex: GRAALVM_java11 }
JAVA_HOME : /usr/lib/jvm/graalvm-ce-java11-20.1.0/  /*記得換成剛才安裝的版本*/
自動安裝 : false

4. 存檔Save

編輯Job就可以選擇 Graalvm了

收工~
