maven Exception in thread "main" java.lang.NoClassDefFoundError when I try to run the application

Question

Build using mvn package is successful. I am able to find dependencies in .m2 repository. But when I try to run using java -jar myjar.jar in Intellij idea or cmd, I get Exception in thread "main" java.lang.NoClassDefFoundError

Whatever dependency I try to use I get Exception in thread "main" java.lang.NoClassDefFoundError

Below is pom.xml
