Where is the root of the classpath directory

Hi

Can someone please advise as to where the root of the classpath directory would be for katalon studio?

I am trying to use Twitter4J.jar and some of the methods require a twitter4j.properties file that needs to be saved in the root of the classpath directory.

http://twitter4j.org/en/configuration.html

Save a standard properties file named “twitter4j.properties”. Place it to either the current directory, root of the classpath directory.

You can get your working directory dynamically:

File currentFolder = new File (System.getProperty(“user.dir”));

Then drill down from there
