Does Burp create a copy of an installed extension?

When developing a new extension, one has to install it multiple times. I noticed that Burp Suite will keep track of where the JAR is originally located when you add it as an extension. I was curious if it's possible to update the JAR at that location and then disable-reenable to update the extension being developed.

Hi Yes, if you rebuild the extension at the same location, and then reload the extension, you will be using your most up-to-date JAR. You can quickly reload an extension by using "Control/Command + Click" on the extension "Loaded" checkbox. Hope that helps!
