In general this function is mainly for internal use but maybe handy for
debugging. The maven repository location can be defined by
set_repository_location(...) or through the option
options("rmaven.m2.repository"=...) option but defaults to a
.m2/repository directory in the rmaven cache directory. This is not the
default location for Maven when used from Java writing to the default Maven
directory in user space is forbidden by CRAN policies. The result of this is
that rmaven will have to unnecessarily download additional copies of Java
libraries, onto the users computer and cannot re-use already cached copies.
Also Maven wont be able to pick up jar files locally installed through
standard Java tooling, unless the default CRAN approved location is overridden
using set_repository_location("~/.m2/repository").
This is more of an issue for developers rather than users.
get_repository_location(settings_path = .settings_path())the file path of the settings.xml to update (generally
the supplied default is what you want to use)

# the default location:

# change the location to the Java default. This change will not persist between sessions.
