所以我只是想使用 JDK 15/SBT 1.5.4/Scala 2.13.6 设置一个项目，所有这些都已通过 MacOS 上的brew 安装。
但是，在我尝试通过 intellij 等进行构建之前，我无法通过普通终端连接到 sbt shell。
[info] welcome to sbt 1.5.4 (AdoptOpenJDK Java 15.0.2)
[info] loading global plugins from /Users/user/.sbt/1.0/plugins
[warn] Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore? (default: r)
Exception in thread "Thread-0" java.lang.NoClassDefFoundError: Could not initialize class com.swoval.runtime.ShutdownHooks
at com.swoval.runtime.ShutdownHooks$1.run(ShutdownHooks.java:25)
我已经尝试重新安装所有三个依赖项几次并清除缓存，但仍然没有任何结果。我猜有些东西配置不正确，因为它甚至无法连接到 shell。
谢谢!
编辑:我刚刚按照 sbt 文档上的安装步骤进行操作，唯一的要求是 JDK 11 或 8 以及 sbt 本身。这次我删除了 scala/JDK15 并通过 SDK-man 重新下载了 JDK 11，但仍然遇到同样的问题。
编辑 2:我已删除 .sbt 目录并重新启动，现在 sbt 命令显示更多输出，希望这会有所帮助。

EDIT3:尝试创建一个新用户并下载 sbt，但仍然遇到相同的问题。将尝试完全删除 Java，因为它似乎是罪魁祸首并重新安装。
最佳答案
与 Boris 的建议类似，问题出在 Java 的安装版本上。
如果您使用 sdk-man 作为包管理器，AdoptOpenJDK 有两个版本，.j9 和 .hs，如下所示:
AdoptOpenJDK | >>> | 16.0.1.j9 | adpt | installed | 16.0.1.j9-adpt
| | 16.0.1.hs | adpt | | 16.0.1.hs-adpt
| | 11.0.11.j9 | adpt | | 11.0.11.j9-adpt
| | 11.0.11.hs | adpt | | 11.0.11.hs-adpt
由于某种原因，OpenJDK 版本 .hs-adpt 在每个版本中都显示此问题，但 .j9-adpt 版本工作正常。
TLDR:安装您需要的 Java 版本 .j9-adpt，否则 .hs-adpt 不适用于我的 sbt 版本 1.5.4 .
