I tried it and I'm using it too, it works like a charm :)

<sf:deploy serverurl="${sf.destinationserverurl}" sessionId="${sf.destinationsessionId}" maxPoll="${sf.maxPoll}" deployRoot="exported_foldername" rollbackOnError="true"/>

Hello! Thanks for this script.

i am using this script for deploying dependency tree before start working. however I am not able to define that the dependent package should be deployed for everyone, instead of only single user.

how would i do that?
