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.
