Navigate to src/main/java and rename the package and the .java File to your liking.

Example: "me.thebusybiscuit.cooladdon" and "CoolAddon.java"
Navigate to src/main/resources/plugin.yml and change the "author" and "main" attributes.
You may also want to change the description to something meaningful.
Navigate to pom.xml and change the group id to "me.%Your name%" and change the artifact id to the name of your Project.
