It should be clear that running this function will affect files in the users filesystem.

The default Maven directory is located in user space and writing to it is
forbidden by CRAN policies. This plugin is set up to use a cache directory
for the local Maven repository but if you are developing Java code and using
it in R then your Java build tools will be installing content to the default
Maven directory, and not the CRAN sanctioned cache. Thus rmaven wont by
default be able to pick up jar files locally installed through standard Java
tooling. This function sets the rmaven repository location to the Maven
standard location allowing local jar files to be used. Obviously this is not
portable until the Java packages are deployed to a Maven repository and is
only an useful option during development.

# We don't run this above example as it creates an empty directory in the
# userspace and doing so in an example violates CRAN principles.
