I am building my project using maven and eclipse. I am using the command mvn assembly:single which runs quite happily. However when I attempt to run the jar using:

java Iris-1.0-SNAPSHOT-jar-with-dependencies.jar

I get:

Exception in thread "main" java.lang.NoClassDefFoundError: target/Iris-1/0-SNAPSHOT-jar-with-dependencies/jar
Caused by: java.lang.ClassNotFoundException: target.Iris-1.0-SNAPSHOT-jar-with-    dependencies.jar

at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

Also the manifest doesn’t contain the class path. The manifest that is produced looks like

Manifest-Version: 1.0
Built-By: maxgarfinkel
Build-Jdk: 1.6.0_29
Created-By: Apache Maven
Main-Class: com.maxgarfinkel.iris.commandLine.CommandLineTools
Archiver-Version: Plexus Archiver

and the pom looks like this:

    You need to do this

    java -jar Iris-1.0-SNAPSHOT-jar-with-dependencies.jar.

    For more information see this link
    http://docs.oracle.com/javase/tutorial/deployment/jar/run.html

    Also there is no need for the manifest to contain the classpath (I think).
