This rule is used for building Scala projects with Bazel. There are currently two rules, scala_library and scala_binary. More features will be added in the future, e.g. scala_test.
scala_libraryscala_library generates a .jar file from .scala source files. In order to make a java rule use this jar file, use the java_import rule.
The current implementation assumes that the files /usr/bin/scalac and /usr/share/java/scala-library.jar exist.
scala_binaryscala_binary generates a Scala executable. It may depend on scala_library and java_library rules.
A scala_binary requires a main_class attribute.
