If you are working with Spring Boot this will solve your problem:

<pre><code>&lt;build&gt;
 &lt;plugins&gt;
 &lt;plugin&gt;
 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
 &lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;

 &lt;goal&gt;repackage&lt;/goal&gt;
 &lt;/goals&gt;
 &lt;/execution&gt;

<ol>
<li>Every mention of "bankim"/"Bankim" refers to my project name, so replace it with your project name that </li>
<li>take special note of the "Start-Class" value. it should contain the "path" to the class that has your main method.</li>
<li>the row:

****the above manifest was created for me by using the "spring-boot-maven-plugin" mentioned above by "Mradul Pandey" (answered Sep 2 '15 at 4:50)

<code>java -jar target/gs-serving-web-content-0.1.0.jar</code> command assumes the provided jar is executable. In an executable jar, the <code>main</code> method is defined in <code>MANIFEST.MF</code> file. Given that you don't have a <code>MANIFEST.MF</code> file, an additional command-line argument can be passed to specify the class containing the <code>main</code> method.

A command like <code>java -cp target/gs-serving-web-content-0.1.0.jar com.pkg.subpkg.MainClass</code> would serve the purpose.
