I've added a new dependency to my POM.
Is there a simple command I can run to download this dependency to my repository?
If you want to only download dependencies without doing anything else, then it's:
mvn dependency:resolve
Or to download a single dependency:
mvn dependency:get -Dartifact=groupId:artifactId:version
If you need to download from a specific repository, you can specify that with -DrepoUrl=...
