Maven : "Caused by: java.lang.NoClassDefFoundError: com/omnesys/omne/om/OMN"

I want to add 3rd party external jar into my maven repository. My project is in Spring Boot.

I had done following things but still I am getting the same error.
NOTE : It working for other jar but not worked only for this jar. Like for DealerSample.jar its working but not working for this jar. You can see the difference in below picture. When I added the same jar in Simple java project through Build path its working but not in Spring Boot project.

Why not try Nexus Repository Manager?
Though this approach may be long and complex. But I think it is the best and lasting solution to your problem. I have used it many times and find it very helpful.

Maven package with Eclipse Project as dependency leads to NoClassDefFoundError

Here is the situation.
I am developing a GUI Client for (historically) CLI based processes. These processes are each under a Maven Project in Eclipse. My GUI is a separate Eclipse Maven Project. The GUI Project references the other projects in its pom.xml, the mvn package doesn't fail, yet when I run the project's ...-jar-with-dependencies.jar I get a NoClassDefFoundError for a child's project class.
Here is my pom.xml

The class that triggers the NoClassDefFoundError is located under the pnl-loader artifactId in the bacardi groupId.
I have already set the scope to compile for the Project dependencies.
Does anyone know what I might be doing wrong ?
Thanks in advance.

Solution to my problem:
The thing was that, although my Eclipse Maven Project had the correct dependency references, it couldn't properly package them in the JAR. Indeed, a project dependency is of no use to Maven (which doesn't know what an Eclipse project is, ofc). Maven goes looking for compiled JARs in his repositories. That's what #aka-one pointed out in the comments. I had to mvn clean install the several projects that were necessary to build in order to finally package my project.

Error after Maven Package

a Project of mine using Commons Chain works fine, when i run it in the IDE.
Now i tried to package it with maven.
I used the following pom.xml:
<build>
<finalName>NAME</finalName>

<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>

As you can see i added the Main Class to my manifest and specified the Dependencies to use.
The package process runs throught, but when i start the jar it says:

Where does this error come from/what do i need to change in my config file?
Greetings,
Nicolas

You need to specify a classpath that has the jar files for your dependencies, something like java -cp=libs -jar main.jar where libs contains the dependency jar files. Maven will set that up for you with the maven-exec-plugin: mvn exec:java -DmainClass=main.Main. Maybe what you want is to have Maven create an "uber jar" that includes all of the class files for your dependencies so that java -jar main.jar just works. Use the maven-assembly-plugin or the maven-shade-plugin to create one. See What is an uber jar?.

Maven doesn't add the classpath to a jar by default.
You need to tell maven-jar-plugin to do that by adding an addClasspath entry to its configuration/archive block.
<addClasspath>true</addClasspath>
(this should be immediately before or after the mainClass line)

exception in ClassLoader executing jar outside of build environment

A simple Cassandra client app using netflix astyanax driver is built in Eclipse. Here is the pom.xml file:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

The app works fine when started from Eclipse. But when the jar file is copied to an external machine it fails to start with the following exception:

The external machine is Amazon t1.micro Ubuntu-12 instance. The only software installed there is Oracle’s Java Runtime Environment 1.7.
It looks like some dependency is missing, but I cannot even see the name of the missing class.
Why did Maven fail to insert some dependency in jar? How do I troubleshoot and resolve such a problem?

It turns out Maven does not include all the dependencies in jar. (I assumed Maven does this automatically). Including all dependencies in jar is explained here:
How can I create an executable JAR with dependencies using Maven?
So I solved the problem by adding the following fragment in my xml file:
