alibaba/p3c ? reverse-engineered prompt

Build me a Java code quality tool based on the Alibaba Java Coding Guidelines.

I want it to check code for the common rules from the guideline, like avoiding deprecated APIs, requiring @Override on overriding methods, using class names for static access, and making hashCode and equals consistent. It should work as a rules engine for code scanning, and also include IDE support so developers can see problems while they type in IntelliJ IDEA and Eclipse.

Please make it feel like a real developer tool, with clear error messages, easy setup, and a way to learn what each rule means. If it helps, look up the current guideline wording online so the checks match the latest version. Also include a formatter or helper tooling if that fits naturally, and make the project usable from a normal Java workflow without extra fuss.
