Add following into pom.xml file and Run as Maven Install. This worked for me.

pom.xml

<packaging>jar</packaging>

 <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.7</maven.compiler.source>
        <maven.compiler.target>1.7</maven.compiler.target>
    </properties>

<build>
    <plugins>

    <plugin>
        <artifactId>maven-assembly-plugin</artifactId>
        <configuration>
            <archive>
                <manifest>
                    <mainClass>com.pohan.App</mainClass>
                </manifest>
            </archive>
            <descriptorRefs>
                <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
        </configuration>
        <executions>
            <execution>
                <id>make-assembly</id>
                <phase>package</phase>
                <goals>
                    <goal>single</goal>
                </goals>
            </execution>
        </executions>
    </plugin>

    </plugins>


</build>

Now Run as Maven Install.

First of all, you have to remember about security in Java. Many jars would not work in fatjars, if they got included in other projects (for example bouncycastle).

If you are doing a simple executable jar that has no libs in it, and requires all of them on classpath, default build (when packageing tag is set to jar) would be ok, and just require a proper manifest.

If you need all libs inside (fatjar), you need to configure it yourself.

There are several plugins for it, for example maven-shade-plugin:

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>2.3</version>
            <configuration>
                <filters>
                    <filter>
                        <artifact>*:*</artifact>
                        <excludes>
                            <exclude>META-INF/*.SF</exclude>
                            <exclude>META-INF/*.RSA</exclude>
                            <exclude>META-INF/*.INF</exclude>
                        </excludes>
                    </filter>
                </filters>
                <transformers>
                    <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                        <manifestEntries>
                            <Main-Class>my.package.MainClass</Main-Class>
                            <Class-Path>.</Class-Path>
                        </manifestEntries>
                    </transformer>
                </transformers>
                <shadedArtifactAttached>true</shadedArtifactAttached>
                <shadedClassifierName>fat</shadedClassifierName>
            </configuration>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

Command line approach:

In the root of the project (the maven project), should be a pom.xml. Go to that root and run mvn package. If this is correct, there should be a new folder with the name target in the root of the project. Inside this folder there should be the jar file.
