sbt-Scala-Brew-MacOS-根本无法连接到sbt shell:NoClassDefFoundError

Question

所以我只是想用JDK 15/SBT 1.5.4/Scala 2.13.6来设置一个项目，所有这些都是通过brew安装在MacOS上的。

然而，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外壳。

[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)

我试过几次重新安装这三个依赖项，并清除了缓存，但仍然一无所获。我猜有些配置不正确，因为它甚至无法连接到外壳。

谢谢！

EDIT：我刚刚完成了sbt文档上的安装步骤，唯一的要求是JDK 11或8以及sbt本身。这次我已经删除了scala/JDK15，并通过SDK man重新下载了JDK11，但我仍然有同样的问题。

编辑2：我已经删除了.sbt目录并重新初始化，现在sbt命令显示了更多的输出，希望这能有所帮助。

编辑3：尝试创建一个新用户，只是下载sbt，但仍然收到相同的问题。将尝试完全删除Java，因为它似乎是罪魁祸首并重新安装。

Answer 1

与Boris的建议类似，问题在于Java的安装版本。

如果您使用sdkman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

出于某种原因，OpenJDK版本.hs-adpt在每个版本中都显示了这个问题，但.j9-adpt版本运行良好。

TLDR：安装您需要的.j9-adpt版本的Java，否则.hs-adpt不适用于sbt version 1.5.4。

Answer 2

我认为原因是——您在使用M1芯片的Mac操作系统时使用了错误的Java JDK。您需要安装正确的Java JDK版本，我使用sdkman。

1. 安装sdk-man:

curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"

2. 设置sdk man不使用rosetta2_compatbile版本：

vim .sdkman/etc/config

并设置sdkman_rosetta2_compatbile=false

3. 从列表中选择java JDK：

sdk list java

================================================================================

并使用命令sdk install java IDENTIFIER安装，即：

sdk install java 16.0.1-zulu
