- interrupts task execution only
- no further tasks scheduled
- existing tasks interrupted
- a task must terminate any other started threads when interrupted
- set cancelable to true to enable
- currently, 'run' properly terminates if the application properly
terminates when interrupted
- 'console' does not, 'test' depends on the test framework
- also bundled: set connectInput to true to connect standard input to forked run
* Allow tasks to provide State transformations that are applied after all tasks complete.
* Provide convenience methods for preserving state across invocations.
* Option of session or persisted state.
Moves many methods previously provided by implicit conversions directly onto the classes
for better discoverability, especially with scaladoc.
1. Initialize now allowed in more places. Minor renamings in Initialize to avoid conflicts
a. map -> apply
b. get -> evaluate
2. Identity on Scoped* is deprecated- it is now redundant
3. Can now use += and <+= for String, Int, Long, Double settings.
There may be some problematic corner cases in inference, especially with +=, ++, <+=, <++=
4. Some classes with a scoped: ScopedKey[T] method now have scopedKey: ScopedKey[T] instead.
5. The implicit conversion to ScopedKey[T] is now deprecated. Use the scopedKey method.
6. :== and ::= are now private[sbt] to better reflect that they were internal use only.
idFun[T]: T => T instead of identity[T](t: T): T
doesn't require a new class file when used as a function value
replaced overloads of :== that assigned the Scoped reference on
the right to the Scoped on the left with <<= scoped.identity
this occurs legally when different dependencies go in
reverse directions, as with delegates
the direct arguments to Project.apply are now call-by-name
the modifying functions like 'aggregate' cannot be call-by-name
since they are varargs
