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

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>
<version>2.4</version>
<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

Answer

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.
