mvn output jar file is executable only inside target folder - maven

Question

I have a mvn built jar, which is working fine inside the target folder.
But if I copy the jar to different folder/machine.I get a class not found exception. I understand the jar is unable to access the dependencies. how can i fix this?
my pom contains,
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<configuration>
<!-- exclude junit, we need runtime dependency only -->
<includeScope>runtime</includeScope>
<outputDirectory>${project.build.outputDirectory}/dependency/
</outputDirectory>
</configuration>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.Main</mainClass>
<classpathPrefix>dependency/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
Thanks In Advance,

Answer 1

Make a fat jar with dependencies using maven-assembly-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>2.4.1</version>
<configuration>
<!-- get all project dependencies -->
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
<executions>
<execution>
<id>make-assembly</id>
<!-- bind to the packaging phase -->
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
The target folder would have additional jar-with-dependencies.jar; you should be able to use this anywhere.

Answer 2

I removed the maven jar and dependency plugins from my pom. Added
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>com.importer.Main</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<finalName>xyz</finalName>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
<executions>
<execution>
<id>make-assembly</id> <!-- this is used for inheritance
merges -->
<phase>package</phase> <!-- bind to the packaging phase
-->
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
This created a jar with dependencies which can be executed anywhere. Also with the specific jar name.
