Create executable jar with Maven

If you are using Maven and wants to create an executable jar file but not getting an exact solution (Google is providing too many results and nothing is straightforward :-)). So let me get this straight and there is a plugin for it which is maven-assembly-plugin.

Below is the pom.xml which makes use of maven-assembly-plugin to generate executable jar:

<?xml version="1.0" encoding="UTF-8"?>
<project
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
       http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.example</groupId>
    <artifactId>test-project</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <properties>
        <targetJdk>1.7</targetJdk>
        <project.build.sourceEncoding>UTF-8
                          </project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8
                          </project.reporting.outputEncoding>
    </properties>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.5.1</version>
                <configuration>
                    <source>1.7</source>
                    <target>1.7</target>
                </configuration>
            </plugin>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.4</version>
                <configuration>
                    <archive>
                        <manifest>
                            <addClasspath>true</addClasspath>
                            <mainClass>com.test.App</mainClass>
                        </manifest>
                    </archive>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies
                                                </descriptorRef>
                    </descriptorRefs>
                </configuration>
                <executions>
                    <execution>
                        <id>make-jar-with-dependencies</id>
                        <phase>package</phase>
                        <goals>
                            <goal>single</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>
    <dependencies>
        <dependency>
            ......
            ......
        </dependency>
    </dependencies>
</project>

Now run "Maven install" and following executable jar file will be created : test-project-0.0.1-SNAPSHOT-jar-with-dependencies.jar
