I am using a Gradle Project for testing APIs, but I need to connect to the database.

I already put this on the dependencies:

But I'm keep getting this error: java.lang.ClassNotFoundException: com.intersys.jdbc.CacheDriver  

Is there any place that I can put a JAR file? Because the project has no lib folder (I already tried to add it, but it doesn't work).
