Ref https://github.com/sbt/zinc/pull/744 This implements `ThisBuild / usePipelining`, which configures subproject pipelining available from Zinc 1.4.0. The basic idea is to start subproject compilation as soon as pickle JARs (early output) becomes available. This is in part enabled by Scala compiler's new flags `-Ypickle-java` and `-Ypickle-write`. The other part of magic is the use of `Def.promise`: ``` earlyOutputPing := Def.promise[Boolean], ``` This notifies `compileEarly` task, which to the rest of the tasks would look like a normal task but in fact it is promise-blocked. In other words, without calling full `compile` task together, `compileEarly` will never return, forever waiting for the `earlyOutputPing`.
