Hi, In maven's site: http://maven.apache.org/guides/mini/guide-mirror-settings.html Creating your own mirror
The central repository requires around 10 GB and growing, and it's updated every 4 hours. You can mirror the central repository using rsync from several mirrors, choose one rsync -v -t -l -r mirrors.ibiblio.org::maven2 /your/local/path rsync -v -t -l -r rsync://rsync.cica.es/maven2 /your/local/path but when I run rsync -v -t -l -r mirrors.ibiblio.org::maven2 /your/local/path on commandline, it can't be execute,there is no " rsync " command,
