In Maven if you are trying to run the application in the CLI, you may have to add the maven-assembly-plugin plugin like below. This plugin will help package all the dependencies in the same target jar file.

NOTE - To update the main class and package name in the <mainclass> tag.


<!-- Add the assemble plugin with standard configuration -->
<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>com.mycompany.app.App</mainClass>
            </manifest>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
</plugin>

You can then compile using maven like below to force the dependencies in the same target jar file.

$mvn clean compile assembly:single

This will add -jar-with-dependencies to the jar file.

To run the built application, you can now do.

java -cp target/my-app-1.0-SNAPSHOT-jar-with-dependencies.jar com.mycompany.app.App arg1 arg2

PS - Thanks to this for the answer, which is in almost the end.
