Since the early days of Griffon it's possible to package an application in several packaging targets; the defaults are jar, zip, applet and webstart. Calling the package command with no arguments will automatically select these 4 targets for you.
But what if you desire a different set to be used when the package command is called without arguments? Since Griffon 0.9.5-rc1 you can specify the following flag in either $appHome/griffon-app/conf/BuildConfig.groovy or $USER_HOME/.griffon/settings.groovy, for example
Executing the package command will now package the application in zip and jar modes only.
If you happen to have the Installer plugin installed on your application you gain access to more packaging targets, like izpack, dmg, rpm and deb. These too can be added to the set of packaging targets you'd want to have executed by default.
Keep on Groovying!
