Compile Scala sources into a Java Archive — spark

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
