I'm using TOS 5.0.2, I added the tTwitterInput component, and when I drag the component to the canvas, it shows an error "Module twitter4j-core-2.1.9-SNAPSHOT.jar is required". I tried to add the jar file in Preferences->Java->Build Path->Classpath Variables, but it doesn't work. Can anybody tell me how I should import this jar file.
