当我更新我的 Steam 平台 Prism Minecraft 启动器时，不再找到 java 安装。
我使用了命令java --version并返回bash: java: command not found
看到 Java 一定因为更新而被卸载了，我决定重新安装 Java sudo pacman -S jre17-openjdk jre8-openjdk，然后重新安装

“警告：jre17-openjdk-17.0.5.u1-1 是最新的 - 正在重新安装”似乎表明 Java 仍处于安装状态，但我尝试过的所有方法都找不到它。我需要找到它，这样我才能在 Prism 启动器中放置它的路径。这里有很多事情要做。任何帮助对于 Linux 新手来说都是值得感谢的。
