Hi, Why are the advantages and disadvantages of creating a XML or Groovy based rule script as opposed to creating a Java Rule Add-on ? When would one approach be recommended over another ?

Ondra, isn't the intent to try to continually improve the XML rules so they have more and more of the functionality of the Java rules?

The XML rules basically provide a short cut for creating rules for Java and XML files. * If you need to create a new report, you will need to write in Java. * If you need to extend functionality beyond what the XML rules provide, you will need to write in Java. * But, if you are trying to just highlight a specific area of a Java code or XML files and provide hints, fall back to leveraging the XML rules. Thanks! Look forward to seeing your rules Samuel!

I think that making them that powerful would actually make them more complicated to use than the Java rules. Having said that, if there are common cases that are requiring Java, we would like to know that. We would like as many rules as possible to be easy to write in the XML format.

I think these questions will appear again as it's a bit confusing subject (Java rules in XML, XML rules in XML, Java rules in Java, ...) So here's a new wiki page where I compiled what was written here. Feel free to edit: https://github.com/windup/windup/wiki/Rules-Difference-Between-XML-based-... (Sande - I hope it doesn't duplicate some such page - ?)
