sbt/MIGRATION.md

Migration notes

• Build definition is based on Scala 2.12.1
• Build.scala style builds are gone. Use multi-project build.sbt.
• Project(...) constructor is restricted down to two parameters. Use project instead.
• sbt.Plugin is also gone. Use auto plugins.
• The incremental compiler, called Zinc, uses class-based name hashing.
• Zinc drops support for Scala 2.8.x, 2.9.x., 2.11.1 and below.
• Removed the pre-0.13.7 *.sbt file parser (previously available under -Dsbt.parser.simple=true)
• Removed old, hyphen-separated key names (use publishLocal instead of publish-local)
• Removes no-longer-documented old operators <<=, <+=, and <++=.
• Renames early command feature from --<command> to early(<command>).
• Log options -error, -warn, -info, -debug are added as shorthand for "early(error)" etc.
• sbt.Process and sbt.ProcessExtra are gone. Use scala.sys.process instead.
• incOptions.value.withNameHashing(...) option is removed.
• TestResult.Value is now TestResult.
• the scripted plugin is cross-versioned now, so you must use %% when depending on it
• Removed the methods settingsSets from Project (along with add/setSbtFiles)
• Dropped deprecated InputTask apply method and inputTask DSL method - replace with Def.inputTask & Def.spaceDelimited().parsed
• Dropped deprecated ProjectReference implicit lifts - replace with RootProject(<uri>), RootProject(<file>) or LocalProject(<string>)
• Dropped deprecated seq DSL method - replace with Seq or just enumerate without wrapping
• Dropped deprecated File/Seq[File] setting enrichments - replace with .value and Def.setting
• Dropped deprecated SubProcess apply overload - replace with SubProcess(ForkOptions(runJVMOptions = ..))
