The following old post describes how to import a Katalon project into other IDE such as IntelliJ IDEA and Eclipse. A magic trick.

As you may know, a Katalon Studio project is essentially an Eclipse project. The IDE products support imporing project created other vendors. So commercial IDE products are potentically able to import the Groovy source codes written in Katalon Studio. Once imported, you may be able to use vast coverages of “Refactoring” features of IDEA and Eclipse. You may be able to get xrefs of class/method references as @Alan_Chan1 wanted.
However you can NOT run the Katalon Test Cases in other IDEs of course.
If you edited the test cases source in IntelliJ IDEA, it is likely you want to export edited source into Katalon Studio. ---- I think you need to invent a way to do this (copy files from dir A to dir B). You shouldn’t export any support by Katalon Studio.
This post may be interesting to someone who want more of refactoring support provided by IDEs.
Thought I haven’t really tried this. Please try at your own risk.

Please note that this is not an official feature. Use this only if you really prefer your IDE.
