Hello Hans, it's DNS ;) You need to make sure, that "repo.maven.apache.org" can be resolved from your docker container (you can use tools such as host, dig, nslookup to verify that). This is may be tricky to debug, unless you're familiar with networking. A good place to start might be checking the /etc/resolv.conf for details about the DNS server being used.
