The test will be meaningless on less than four cores, but the
scripted test will pass. On four or more cores, the test wil
test testForkedParallel as expected.
Closes#3545
As of Scala 2.11 Predef.conforms isn't implicit anymore (and it's
deprecated), so import-excluding doesn't avoid the implicit (the
implicit version is now Predef.$conforms). Also in Scala 2.13
Predef.conforms has been removed.
This works around the name conflict between sbt.test package and sbt.Keys.test.
1. sbt.test package is renamed to sbt.scriptedtest. This allows 1.0 plugins and builds to use `test` to mean `Keys.test`.
2. To keep binary compatibility for sbt 0.13 scripted, I am adding `sbt.test.ScriptedRunner` and `sbt.test.ScriptedTests` in `scripted-plugin` artifact.
3. Another affected user is Giter8 plugin that uses ScriptedPlugin. Since the intereactions are limited to `sbt.ScriptedPlugin.*`, we should be fine here. - https://github.com/foundweekends/giter8/blob/v0.11.0-M2/plugin/src/main/scala-sbt-1.0/giter8/SBTCompat.scala
Fixes#3538
This brings in `sbt.ScriptedPlugin` as `sbt.plugins.ScriptedPlugin` into sbt mothership.
In addition, `sbt.plugins.SbtPlugin` is added that enables the scripted plugin and `sbtPlugin := true`.
This allows plugin authors to bring in scripted plugin by writing:
```scala
lazy val root = (project in file("."))
.enablePlugins(SbtPlugin)
```
The change to enable batched and parallel execution for scripted was
done only for the scripted-sbt project. This pull request enables it for
scripted-plugin, so that all sbt plugins in 1.x. can benefit from it.
By default, it configures a number of parallel instances of 1 and batch
execution is disabled. Users can change the number of parallel sbt hosts
running scripted tests via the `scriptedParallelInstances` setting.
In some plugins scripted tests', batch execution can cause issues
because the first time `>` commands are executed they assume sbt starts
up. This error can be fixed by doing `reload` before running the `>`
command.
Note that the current scripted plugin does not allow parallel execution
in non-batched mode.
