This is EXACTLY what I am working on: a tool CLI-friendly to be used to check the quality of Java code. It has also an interactive modality. You can run single queries (to check for single warnings) or all queries together.
The tools is in its early stage but I am working on it almost every day. It is available here:

Please let me know what do you think about it and feel free to ask questions.
