debian 12 bookworm 安装openjdk 8

Posted on Edited on In

这里安装Adoptium组织的Eclipse Temurin项目的openjdk

  1. 背景

Adoptium工作组是Eclipse基金会的子组织，在加入Eclipse之前，叫AdoptOpenJDK，加入之后改名为Eclipse Adoptium

Adoptium负责的项目Eclipse Temurin是一个OpenJDK的发行版。

Temurin这个名字来自于runtime的两个音节前后颠倒。

  1. 安装必要的包
1
$ sudo apt install -y wget apt-transport-https gpg
  1. 获取Eclipse Adoptium GPG key
1
$ wget -qO - https://packages.adoptium.net/artifactory/api/gpg/key/public | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/adoptium.gpg > /dev/null
  1. 配置Eclipse Adoptium apt源
1
echo "deb https://packages.adoptium.net/artifactory/deb $(awk -F= '/^VERSION_CODENAME/{print$2}' /etc/os-release) main" | sudo tee /etc/apt/sources.list.d/adoptium.list

配置完后是这样的：
