Question on jQuery/jQuery UI License

Hi Guys,
I'm doing a small project. The goal is simple: to collect any useful
jQuery plugin and store them into one single JAR that will be
published in a public repository (googlecode), accessible to Maven,
Ivy, Gradle, and so on (I'm a Java Developer). I wonder what License I
should put in the JAR? MIT, GPL, or both?
Thanks!!! ^^
