scalaDevelDownloadJARs: Download and Deploy JAR Files into the Package File System

Description

This function only takes effect during package installation. It is meant to be called from bare code of a package that depends on rscala in a script such as zzz.R. When called during package installation, it downloads JAR files to the appropriate directories. This avoids the need to distribute some JAR files in the source package.

Usage

scalaDevelDownloadJARs(
