sbt/notes/1.0.1.markdown

This is a hotfix release for sbt 1.0.x series.

Improvements

• Various improves around watch source feature. See below.

Bug fixes

• Fixes command support for cross building + command. The + added to sbt 1.0 traverses over the subprojects, respecting crossScalaVersions; however, it no longer accepted commands as arguments. This brings back the support for it. #3446 by @jroper
• Fixes addSbtPlugin to use the correct version of sbt during cross building. #3442 by @dwijnand
• Fixes run in Compile task not including Runtime configuration, by reimplementing run in terms of bgRun. #3477 by @eed3si9n
• Shows actual as a potential option of inspect #3335 by @Duhemm
• Includes base directory to watched sources. #3439 by @Duhemm
• Adds an attempt to workaround intermittent NullPointerException around logging. util#121 by @eed3si9n
• Reverts a bad forward porting. #3481 by @eed3si9n

WatchSource

The watch source feature went through a major change from sbt 0.13 to sbt 1.0 using NIO; however, it did not have clear migration path, so we are rectifying that in sbt 1.0.1.

First, sbt.WatchSource is a new alias for sbt.internal.io.Source. Hopefully this is easy enough to remember because the key is named watchSources. Next, def apply(base: File) and def apply(base: File, includeFilter: FileFilter, excludeFilter: FileFilter) constructors were added to the companion object of sbt.WatchSource.

For backward compatibility, sbt 1.0.1 adds += support (Append instance) from File to Seq[WatchSource].

So, if you have a directory you want to watch:

watchSources += WatchSource(sourceDirectory.value)

If you have a list of files:

watchSources ++= (sourceDirectory.value ** "*.scala").get
