我想根据此处的文档通过 sbt 方式设置 scala 脚本。
执行时遇到错误
java -Dsbt.main.class=sbt.ScriptMain -Dsbt.boot.directory=/home/user/.sbt/boot -jar sbt-launch.jar "$@"
错误信息：

我不确定 show 是否-Dsbt.main.class=sbt.ScriptMain意味着。
该文件也令人困惑：
将根据 Setup 设置的标准 sbt 脚本复制为 scalas 和 screpl（或任何您喜欢的名称）。
什么是标准的 sbt 脚本？
scalas 是脚本运行器，应该使用 sbt.ScriptMain 作为主类
在哪里sbt.ScriptMain或如何定义它？
