In this the last part of this four-part series I will zoom carefully into the ease of use of PMD. I totally enjoy PMD. The reason for this is the relative simplicity of writing your own bug pattern-capturing rules and using them under fire. More on that later. To round off we have included an in-depth interview with Tom Copeland, the author of PMD Applied and the newer JavaCC . It is no coincidence that Tom is at the center of the PMD development thrust.
Note: this is Part 4. Feel free to read Part 3!
