How to include test classes in Jar created by maven-shade-plugin?

Question

I'm trying to package my test classes in to an executable jar with dependencies using Maven, but I'm struggling to get this right.

This is my pom.xml so far:

<project>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.c0deattack</groupId>
    <artifactId>executable-tests</artifactId>
    <version>1.0</version>
    <packaging>jar</packaging>

    <name>executable-tests</name>

    <dependencies>
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-java</artifactId>
            <version>1.0.0</version>
        </dependency>
        <dependency>
            <groupId>info.cukes</groupId>
            <artifactId>cucumber-junit</artifactId>
            <version>1.0.0</version>
        </dependency>

        <dependency>
            <groupId>org.seleniumhq.selenium</groupId>
            <artifactId>selenium-java</artifactId>
            <version>2.21.0</version>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.10</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>

                <executions>
                    <execution>
                        <goals>
                            <goal>test-jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-shade-plugin</artifactId>
                <version>1.6</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>shade</goal>
                        </goals>
                        <configuration>
                            <finalName>cucumber-tests</finalName>
                            <transformers>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                    <mainClass>cucumber.cli.Main</mainClass>
                                </transformer>
                            </transformers>
                            <artifactSet>
                                <includes>
                                    <include>info.cukes:*</include>
                                </includes>
                            </artifactSet>
                        </configuration>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>com.c0deattack</groupId>
                        <artifactId>executable-tests</artifactId>
                        <version>1.0</version>
                        <type>test-jar</type>
                    </dependency>
                </dependencies>
            </plugin>
        </plugins>
    </build>
</project>

When I execute mvn clean package the build creates 3 jars:

• executable-tests-1.0.jar // built by the mvn package phase
• executable-tests-1.0-teststjar // built by the jar-plugin
• cucumber-tests.jar // build by the shade-plugin

Cucumber-tests.jar contains the info.cuke dependencies but it doesn't contain the executable-tests-1.0-tests.jar.

I've done all sorts of things to try and have the test classes included but nothing has worked, what am I missing?

Edit: I've pushed my example project to GitHub if any one fancies playing around with it :) https://github.com/C0deAttack/ExecutableTests

I've solved my problem a different way; using two other plugins.

First I use the maven-dependency-plugin to get the dependencies and unpack them locally, then I use the maven-jar-plugin to create a test-jar and include the classes from the unpacked dependencies.
