NoClassDefFoundError and I have no idea how to solve it

[Sujamma]

I am trying to create a new script with IntelliJ Idea, but whenever I try to use my Utility.jar, I get this error:

java.lang.NoClassDefFoundError: Utility/Sleep
    at Main.TanHide(Main.java:80)
    at Main.onStart(Main.java:48)
    at org.osbot.rs07.event.ScriptExecutor.iiiIIiiiiiii(hl:205)
    at org.osbot.rs07.event.ScriptExecutor.start(hl:125)
    at org.osbot.CB.iiiIIiiiiiii(jz:262)

    at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)
Caused by: java.lang.ClassNotFoundException: Utility.Sleep
    at java.net.URLClassLoader.findClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    at java.lang.ClassLoader.loadClass(Unknown Source)
    ... 9 more

It lets me import the script, use the methods and so on. The script compiles fine, but whenever I try to use the script inside the OSBot client it fails with the error. 

I am not really sure what information would help resolve this, so I will be happy to clarify any questions. Any kind of help is appreciated.

You need to extract the jar into the output root in artifacts

Output root? I am not sure what that is. I designated the output folder in artifacts, the jar is successfully created in the folder I chose. Do you mean I should set the output directory to a specific folder?
