One of the pains of working with Eclipse RC releases is moving from one to another. I don’t like using downloaded plug-in packs such as WTP, Mylar, Spring IDE, TestNG, Subclipse, etc. because they get updated pretty frequently, especially to keep up with changes in the RC releases. But I also hated having to keep track of all the update site URLs that each of them has. Then, someone says, “Why don’t you just export your sites and then import them when you drop in a new Eclipse RC?” Doh! I have no idea why I missed that button before. Sometimes I just don’t look at the UI I’m using.
