Debugging like a pro

This page is still being written.

What it will cover

• The debugging mindset: reproduce, isolate, read the error, change one thing
• Logging with getLogger().info/warning and a debug flag in config
• IntelliJ debugger with the Run Paper Server debug button: breakpoints, stepping, watches, evaluate expression (x-mock references)
• Reading stack traces from the server console (annotated example with Caused by and your plugin line)
• Common runtime problems: listener not registered, event handler not public, wrong event import, command not registered, config not saved, plugin.yml main mismatch
• Binary search debugging (comment out is not allowed in our code style: explain toggling code by early return instead)
• Link to Error Doctor and FAQ
• Example plugin with a deliberate bug to find (plugins/debugging-demo) and its fixed version described
