NoClassDefFoundError + ClassNotFoundException when executed from a JAR

Question

My program has an exception when I run as a JAR from bash, but not from IntelliJ. What is going wrong?

Exception in thread "main" java.lang.NoClassDefFoundError: org/jsoup/Jsoup
        at EndUserHandbook.getLinkList(EndUserHandbook.java:53)
        at EndUserHandbook.main(EndUserHandbook.java:24)

tell us what is in your dependency tab except pom. Have you added lib jar in your own jar OR in classpath — Ravi Parekh, May 24 '17 at 08:46

How did you launch your program? The way to launch a jar file is java -jar file.jar. java file.jar doesn't work.

That's exactly how I launched it. ``java -jar file.jar``. – Martin Erlic May 24 '17 at 08:26
Can you try to add `compile` to your dependencies? According to [this topic](https://stackoverflow.com/questions/12811392/java-classnotfoundexception-with-maven-dependency), it should work. – Abrikot May 24 '17 at 08:35
