Is it possible to generate the javadoc for all our Custom Keywords from katalon studio? Since Katalon studio looks like it was based on Eclipse, I thought there would be an option but I couldn’t find any.
No, I don’t think there is anything to actually generate the javadoc HTML files. (If someone knows different, please speak up).
However, your javadoc source comments are generated “live” in the Katalon environment and work perfectly well.
