Getting java.lang.ClassNotFoundException error when running Spring Boot application jar file

Question

I have created a jar file of a SpringBoot application using gradle.However when I try to run the jar file I am getting the following error:

Here is a SS of the entire project structure along with the build.gradle file content

Cant seem to figure out the problem. Getting this error whenever I run the jar file. I created the jar file using "gradle build" command

I used the full package name : "com.example.websocketdemo.WebsocketDemoApplication" But it is still showing same error — SIM777, Jan 28 '23 at 15:47
Try to run `java -jar .jar` from the command line to see if it works. If it works, please share a screenshot of your IDEA's run configuration (IDE main menu `Run | Edit Configurations`). — floating cat, Jan 29 '23 at 02:53
