sbt core concepts
summary
sbt treats commands as commands as state transformations (sequential, interactive checkpoints) and tasks as composable dataflow nodes so most work runs in parallel; the .value/applicative model makes many task dependencies execute concurrently and guarantees compile called once per run for minimal re-evaluation. sbt 1.3 adds shorter semicolon composition, native file watching plus tilde live-reload and testQuick incremental tests, and turbo mode plus super-shell for faster JVM/classloader reuse and clearer concurrent task status.
