I attended IntelliJ IDEAL plug-in contest with Batch Generator. It's my first IntelliJ IDEA plug-in. It's not complex enough to earn me $5000 plus a bunch of software but it's good enough to help me to have a new T-shirt. Beyond this, after a painful lesson, I learned a new lesson: When you have an idea, please do it, do it immediately. It's the biggest prize for me at this time.
Batch Generator 1.0: plug-in, source code, license, user's guide
For the idea to create this plug-in, you can see here.
