scala - 全局禁用 sbt supershell

Question

类似于this question我想阻止 sbt 使用消息和空行向 shell 发送垃圾邮件。如果我使用选项 sbt -Dsbt.supershell=false 运行 sbt，它会停止，但我想通过 ~/.sbt 或类似的点文件全局禁用它.我可以用总是添加此选项的包装器替换 sbt 二进制文件，但这似乎不够优雅。

我在名为 ~/.sbt/1.0/global.sbt 和 ~/.sbt/1.3/global.sbt 的文件中尝试了以下各项，但都没有效果:

sbt.supershell := false
useSuperShell := false
sbt.useSuperShell := false
useSuperShell := false
supershell := false
ThisBuild / useSuperShell := false

作为我试图避免的一个例子，当我为我正在处理的项目启动 sbt 时会发生什么(在编译、测试时会散布类似数量的垃圾邮件等):

[info] sbt server started at local:///Users/chris/.sbt/1.0/server/bba992971696ad25eaa9/sock

Answer 1

sbt launcher script提供 sbt -help 应该打印出在我的机器上运行 brew install sbt 安装 sbt 1.3.12 后全局配置的位置

  SBT_OPTS            environment variable, if unset uses ""
  .sbtopts            if this file exists in the current directory, its contents
                      are prepended to the runner args
  /usr/local/etc/sbtopts    if this file exists, it is prepended to the runner args

所以试着把

-Dsbt.supershell=false

在 /usr/local/etc/sbtopts 中，这是 sbt 的系统范围配置文件。但是我可以看到 source 中指定的默认位置code 是 /etc/sbt/sbtopts 然后 brew 似乎是 replace

s.gsub! 'etc_sbt_opts_file="/etc/sbt/sbtopts"', "etc_sbt_opts_file=\"#{etc}/sbtopts\""

因此我认为最安全的做法是运行 sbt -h 来查看您机器上的值是多少。我不熟悉 nixpkgs，但你可以看看它的 source对于 sbt，或者直接分析生成的 sbt 启动器脚本中的 etc_sbt_opts_file 变量

vim `which sbt`
