In a .classpath file in a Katalon project, I found the following line:
<classpathentry kind="lib" path="/Applications/Katalon Studio.app/Contents/Eclipse/plugins/net.sf.supercsv.super-csv_2.1.0.jar"/>
This implies that Katalon Studio uses Super CSV library for its own sake (Katalon can write test reports in CSV, you know). Any user can reuse the Super CSV in their own codes . They do not have to explicity import the jar into Katalon project.
