ExtractDependencies

This phase sends information on classes' dependencies to sbt via callbacks.

This is used by sbt for incremental recompilation. Briefly, when a file changes sbt will recompile it, if its API has changed (determined by what ExtractAPI sent) then sbt will determine which reverse-dependencies (determined by what ExtractDependencies sent) of the API have to be recompiled depending on what changed.

See the documentation of ExtractDependenciesCollector, ExtractAPI, ExtractAPICollector and http://www.scala-sbt.org/0.13/docs/Understanding-Recompilation.html for more information on how sbt incremental compilation works.

The following flags affect this phase: -Yforce-sbt-phases -Ydump-sbt-inc

Is this phase the standard typerphase? True for FrontEnd, but not for other first phases (such as FromTasty). The predicate is tested in some places that perform checks and corrections. It's different from isAfterTyper (and cheaper to test).
