I've been creating a soap server with java for my company and I just recently switched over to using Bone-CP and Maven to import all the required 3rd party programs. After I finished implementing bone-CP I used the server command
jar -cvfm SoapServer.jar manifest.txt SoapServer
And when I transfered it to my server and tried to run it I got this error:
Exception in thread "main" java.lang.NoClassDefFoundError: SoapServer/SoapServer (wrong name: com/test/SoapServer/SoapServer)

The only think I can think of causing the problem is that maven doesn't package the required JARs with the program? If that's the case do I just need to download them and add them to the class path?

lang. NoClassDefFoundError, which means the Class Loader file responsible for dynamically loading classes can not find the . class file. So to remove this error, you should set your classpath to the location where your Class Loader is present.
The reported classpath consists of references to JAR files cached in local Maven repository. Even the JAR artifact of the project is referenced from local Maven cache and not from the /target directory one or the other might expect.
The NoClassDefFoundError is a runtime error in Java that occurs if the Java Virtual Machine (JVM) or a ClassLoader instance attempts to load the definition of a class that could not be found. The class definition exists at compile-time but is not available at runtime.
If you need all of your dependencies to be packed in the executable jar then configure your pom like
<build>
<plugins>
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.something.YourMainClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
above block will add all the library in lib/ to classpath in manifest classpath entry
and to copy all the dependencies to lib directory
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.1</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/lib</outputDirectory>
<overWriteReleases>false</overWriteReleases>
<overWriteSnapshots>false</overWriteSnapshots>
<overWriteIfNewer>true</overWriteIfNewer>
</configuration>
</execution>
</executions>
</plugin>
