Answer 1

You can use maven-jar-plugin

<plugin>
<artifactId>maven-jar-plugin</artifactId>
<version>2.6</version>
<configuration>
    <archive>
        <manifest>
            <addClasspath>true</addClasspath>
            <classpathPrefix>lib/</classpathPrefix>
            <mainClass>com.poc.sms.MainApp</mainClass>
        </manifest>
    </archive>
</configuration>
</plugin>

Answer 2

The maven-shade-plugin creates a jar with your application code and all dependencies merged into a single jar file. The problem with this approach is that you need to decided what to do with files with conflicting names. This is the configuration we use to build executable JARs for our Camel apps, including Spring and all required dependencies.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <version>1.5</version>
    <configuration>
        <transformers>
            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
