Grapes is a great utility to manage class path automation when coding with groovy.
But it slows down the start-up if there are a lot of dependent jars to download. Even all the dependent jar files have been downloaded to local m2 and grapes store previously, the download process still takes place, which slow things down unnecessarily.
Use the following options to ask groovy look into local storage directly.
groovy -Dgroovy.grape.autoDownload=false [groovy file path] [arguments ......]
