#' Set/Append Maven Artifact Repositories
#'
#' \code{set_mvn_repos} will overwrite any existing repos and
#' \code{add_mvn_repos} will append/prepend to existing.
#'
#' These repositories are only used by the \code{dependency:get} maven plugin, so they
#' will be used when calling \code{\link{get_dependencies}} but not when calling
#' \code{\link{build_classpath}} (which uses the \code{dependency:build-classpath} maven
#' plugin under the hood). To set repositories for building classpaths it is necessary
#' to update the maven settings.xml file. This is typically found in \code{~/.m2/settings.xml}.
#'
#' @param repos Character vector. Should be maven repo URLs
#' @param prepend Logical. If \code{TRUE} the new paths will come before the old.
