Can you verify that the class exists in your project? Have you compiled the project? What happens when you run 'mvn clean compile exec:java -D storm.topology=fyp-storm-try.src.jvm.Topology'? Also, unless you have a very good reason for doing so, or you don't care about nuking your computer, I strongly suggest you stop executing a development project with sudo privileges.
