Have a big project spread into multiple subprojects and have to fix imports, add/check javadoc, or other tasks that will take hours, even days, to accomplish manually?
Then you'll love "Inspect & Transform" in NetBeans IDE 7.1. There are many options available and you can select the scope where to apply the changes. Then press a button and all the work is done for you.
You can configure it to your needs and create a category for your projects with all the things you want to have done.
You can even create your own hints in Java or use a simple declarative language without needing to touch a line of Java and without needing to write a NetBeans module.
This is a great addition to this great IDE!
