Jaspersoft Studio Error on Start Up

jbreault · August 2, 2017

Whenever I open Jaspersoft Studio, I immediately get an error stating "Reason: Invalid signature file digest for Manifest main attributes". If I view the details, it says what is below. This problem arised when I was trying to create scriptlets from classes in external jar files. Now Jaspersoft Studio doesn't function properly at all for any report. The Design and Preview tabs are empty. I am looking for a way to make Jaspersoft Studio functional again, and why this happened in the first place. Any help is appreciated.

java.lang.SecurityException: Invalid signature file digest for Manifest main attributes
