In Java, deal with NoClassFoundError

Question

My project is built using Apache Maven JAR Plugin, I'm using ini4j inside my project managed by maven, on the IDE, everythin works fine. But when i try to launch the JAR in the cmd as follow : java -jar javaProgram-1.0-SNAPSHOT.jar

I get this error :

Exception in thread "main" java.lang.NoClassDefFoundError: org/ini4j/Ini
        at org.example.Main.main(Main.java:14)
Caused by: java.lang.ClassNotFoundException: org.ini4j.Ini
        at java.net.URLClassLoader.findClass(URLClassLoader.java:387)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:418)

        at java.lang.ClassLoader.loadClass(ClassLoader.java:351)
        ... 1 more

Here is the manifest.mf inside the .jar:

Any idea how i could provide everything while keeping maven? The goal would be to build the .jar and to launch it in the cmd instead of runnig it in the IDE

EDIT : This problem has been solved using the Apache Maven Shade Plugin allowing you to fix the problem by running the shaded jar.
