我正在https://www.scala-sbt.org/1.x/docs/sbt-by-example.html当我在添加插件的步骤"添加sbt原生打包程序插件"后重新加载时，它失败了，并出现了许多警告和错误，提示为"项目加载失败：(r(etry、(q(uit、(l(ast或(I(gnore？"此时sbt基本上已经死了。我将附加一个错误的完整捕获。
我相信我遵守了所有的指示。出了什么问题？
我试过：
- 重新启动sbt
- 撤消教程要求的最新代码(plugins.sbt和build.sbt中的更改(并重新启动sbt。然后sbt又活了，但当然，当我把代码加回来时，它又死了
-
为我所知的其他转发添加解析器，
- 中提到的内置解析器https://www.scala-sbt.org/1.x/docs/Resolvers.html
- resolvers+="apache repo"位于https://repo.maven.apache.org/maven2/com/typesafe/">
-
解析器+="lightbend"在"https://repo.lightbend.com/typesafe/releases/">
-
解析器+="lightbend"在"https://repo.lightbend.com/typesafe/ivy-releases/">
- 完全替换"resolvers"变量，以防早期变量破坏进程
- 将请求的版本从"1.3.4"更改为sbt本机的其他版本-我知道存在的包装商。基本上是同一个故事，不同的版本号
由于我是Scala和sbt的新手，我可能错过了一些基本的东西，但我只是没有看到。

我发现了问题所在——无论如何，大致是这样。它下面的Sbt和Java似乎有过时的安全证书。奇怪，因为我本周刚刚安装了它。
命令：
sudo /var/lib/dpkg/info/ca-certificates-java.postinst configure
更新了相关证书，然后它就工作了。
