executable jar with dependencies using maven

Question

I tried tons of posts from all around the web by changing my pom file for n number of times. Still I am not able to create a executable jar with all the dependencies. Final jar is missing the main class. But, I can see the same in Manifest.mf file. following is my pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</build>

tried all these mvn package mvn clean install mvn clean compile assembly:single

but no luck, main class is not included in the jar. following is my manifest.mf

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: userName
Build-Jdk: 1.7.0_60
Main-Class: com.sample.app.SomeMainServer

How have you structured your project? Maven will bundle classes defined under src/main/java. — JamesB, Aug 01 '14 at 13:39
Is it in the target folder? IF it is I'm assuming it's the Assembly plug-in that may be messing something up. Maybe you would have better luck with the Shade plugin? — Mikkel Løkke, Aug 01 '14 at 14:23
Why the assembly plugin? You can just use the standard maven-jar-plugin and specify the main-class to it. That's what I've always used and it works just fine. http://maven.apache.org/shared/maven-archiver/examples/classpath.html — Gimby, Aug 01 '14 at 14:41
@Gimby post it as an answer, will accept it..It did solve the issue. — user1609085, Aug 01 '14 at 14:58

As per request in the comments I post this answer:

The jar is built using the maven-jar-plugin, so you can just specify the main-class to it as per the documentation: http://maven.apache.org/shared/maven-archiver/examples/classpath.html
