With sbt 1 in beta and the final release coming up bug reports and reproductions will start to diversify between sbt 0.13 and sbt 1. So let's try and get reporters to specify the version they're using.
Before, we were not preserving the value `insideXXX`. This commit makes
sure that we handle much more complex scenarios and we report them
successfully. Have a look at the tests.
The missing .value analysis is dumb on purpose because it's expensive.
Detecting valid use cases of idents whose type is an sbt key is
difficult and dangerous because we may miss some corner cases. Instead,
we report on the easiest cases in which we are certain that the user
does not want to have a stale key reference. Those are idents in the rhs
of val definitions with `_` as name and idents in statement position
inside blocks.
In the future, we can cover all val definitions no matter what their
name is. Unfortunately, doing so will come at the cost of speed: we have
to run the unused name analysis in `TypeDiagnostics` and expose it from
the power context in `ContextUtil`.
This is good enough for now. If users express interest in having a
smarter analysis, we can always consider trying the unused name
analysis. I am not sure how slow it will be -- hopefully it won't be
that much.
This ports sbt-cross-building's cross (`^`) and switch (`^^`) commands.
Instead of making it a plugin, the default settings are now changed
to use `sbtVersion in pluginCrossBuild` for the sbt dependency.
In sbt 0.13.15, in addition to notifying the user about the existence of
sbt's shell, a feature was added to allow the user to switch to sbt's
shell - a more pro-active approach to just displaying a message.
Unfortunately sbt is often unintentionally invoked in shell scripts in
"interactive mode" when no interaction is expected by, for exmaple,
invoking `sbt package` instead of `sbt package < /dev/null`. In that
case hitting [ENTER] would silently trigger sbt to run its shell,
easily wrecking the script. In addition to that I was unhappy with the
implementation as it created a tight coupling between sbt's command
processing abstraction to sbt's shell command.
If you want to stay in sbt's shell after running a task like `package`
then invoke sbt like so:
sbt package shell
Fixes#3091
This is a change in strategy.
The motivation is the need to find a good balance between:
+ informing the uninformed that would benefit from this information, &
+ not spamming the already informed
Making it dependent on "compile" being present in remainingCommands will
probably make it trigger for, for example, Maven users who are used to
running "mvn compile" and always run "sbt compile", and who therefore
are unneccesarily suffering terribly slow compile speeds by starting up
the jvm and sbt every time.
