@Ibruun's solution is the one currently used by Sonatype at

https://help.sonatype.com/repomanager3/installation/run-as-a-service#RunasaService-systemd

But the fact that systemd still starts an (really complex) init script /apps/nexus/current/bin/nexus is jarring; that's not how it is supposed to be done....

@dtonhofer instead of ./bin/nexus start, do you think ./bin/nexus run would work with Type=simple?

@glynnforrest I don't know, you will have to try. But there is no good reason to change from the forking modus, is there?

@dtonhofer I did run it but wasn't sure if it would break nexus in some subtle way. nexus run spits the logs out to stdout so they appear in the systemd journal, which is quite handy.
