Compile Scala sources into a Java Archive

Description

Given a set of scala source files, compile them into a Java Archive (jar).

Usage

spark_compile(
  jar_name,
  spark_home = NULL,
  filter = NULL,
  scalac = NULL,
  jar = NULL,
  jar_dep = NULL,
  embedded_srcs = "embedded_sources.R"
)

Arguments

`spark_home`	The path to the Spark sources to be used alongside compilation.
`filter`	An optional function, used to filter out discovered `scala` files during compilation. This can be used to ensure that e.g. certain files are only compiled with certain versions of Spark, and so on.
`scalac`	The path to the `scalac` program to be used, for compilation of `scala` files.
`jar`	The path to the `jar` program to be used, for generating of the resulting `jar`.
`jar_dep`	An optional list of additional `jar` dependencies.
`embedded_srcs`	Embedded source file(s) under `<R package root>/java` to be included in the root of the resulting jar file as resources
