Program runs fine in IDE but not as Jar file

I have exported a jar file that I want to run the console. The code compiles and runs correctly in eclipse but I am having an issue running it from the console.

enter image description here

To me it looks like the referenced jar's I added via built path in the Eclipse project file and not being added to the export. If that is the case, how do I ensure that they do? If not, what am I doing wrong?

When you export your source code's class files to a jar using eclipse, only the .class files of your source are exported! Hence your exported jar file doesn't contain the referenced jars you mentioned in eclipse! Due to this, the error occurs while executing from command prompt.

Solution:
Take all the jar files required to execute the program, store it in the same directory as you store the exported jar file. Now while executing the java command, provide all the jar file's names in classpath field as following:

java -classpath .;JAR1.jar;JAR2.jar MainClass

Once you do this, your problem should be resolved!

When running from the command line make sure any dependencies are set on the class path by listing them in the -classpath parameter

The dependencies need to be on the classpath, i.e. run like this:

java -cp <path_to_jar1>;<path_to_jar2> -jar ScrumTimeCaptureMaintenence.jar
