no privileged project member of State
no separation of Command and Apply, so no pre-filtering on State
use entries in State attributes map instead of mixing in traits to project object:
HistoryPath, Logger, Analysis, Navigate, Watch, TaskedKey
rework Navigation to be standalone instead of mixin
add syncTask task constructor and copy-resources/copy-test-resources instances
add console-quick, test-console, console, test-run
add IntegrationTest trait
make Context available through 'context' task
update 'last' and 'show' to use Context to retrieve task by name
drop SingleProject (superseded by Project)
add TaskGroup to be able to inject groups of named tasks
fix watchPaths missing flat sources
proper logging in a few more places, such as compile
the custom scalac Reporter now delegates to an instance of
an sbt interface called xsbti.Reporter
handling compilation logging is now mainly done on the sbt-side of the
compiler interface
the xsbti.Reporter interface provides access to richer information
about errors and warnings, including source file, line, and offset
xsbti.Reporter can be implemented by users to get access to
detailed information without needing to parse the logging output
the CompileFailed exception that is thrown when compilation fails now
includes an array of the problems, providing detailed
error and warning information that can, for example, be consumed
by doing a mapFailure on 'compile' and using 'Compile.allProblems'
updated compile tests for new minimal AnalysisCallback
moved discovery to discovery/ subproject and updated for new approach
fixed discovery to only find public methods when searching for annotated definitions
extracting inherited definitions unimplemented in api/, so some discovery tests fail
moved discovery classes from sbt.inc package to sbt.compile
for use from project definitions only-
it is a top-level project
add dependency and repository builders
cross-versioning will be a post-construction transformation
