      Probably the most useful SBT tip I'll ever give: java -cp $(cat .cp || sbt 'export runtime:fullClasspath' | tail -n1 | tee .cp) <main-class>

      Stupid question: what's the last line of sbt's class path?

      It's the entire class path (colon-separated) of your project. Does that answer the question?

      Oh, totally makes sense. I was just surprised that the tail was needed. But sbt does like to spam on startup so that makes sense. Thank!

      Yeah, I think that spam is unavoidable. By the time you get a chance to tell it not to, it's already too late.

      the spam is avoidable with `--error`; the issue of record is https://github.com/sbt/sbt/issues/840 …

      I still get a spurious `[success]` line in the output. Any idea how to elide that too?

          This works for me: sbt 'export runtime:fullClasspath' < /dev/null > .cp
