maven include testOutputDirectory in the jar - maven

Question

Want to add the testoutputdirectory files in the project jar. Tried using below but, the test classes were not included in the jar
What need to be changed to include the same in the project jar?
Using below in the pom.xml
<build>
<finalName>${project.name}</finalName>
<testOutputDirectory>test/classes</testOutputDirectory>
<resources>
</resources>
<plugins>
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<finalName>${final.name}</finalName>
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
</archive>
<descriptor>./src/main/resources/assembly/assembly.xml</descriptor>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
<appendAssemblyId>false</appendAssemblyId>
</configuration>
<executions>
<execution>
<id>jar-with-dependencies</id>
<phase>package</phase>
<goals>
<goal>single</goal>
</goals>
</execution>
</executions>
</plugin>
.........
</build>
Below I have in the assembly.xml
<assembly xmlns="http://maven.apache.org/ASSEMBLY/2.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/ASSEMBLY/2.0.0 http://maven.apache.org/xsd/assembly-2.0.0.xsd">
<moduleSets>
<moduleSet>
<sources>
<fileSets>
<fileSet>
<directory>.</directory>
<outputDirectory>/</outputDirectory>
<includes>
<include>test/classes/**/*.class</include>
</includes>
</fileSet>
</fileSets>
</sources>
</moduleSet>
</moduleSets>
</assembly>

Answer 1

I dont think it is a good idea to do that at all. Maybe think about to create a separate test-jar. You can do it with the maven-jar-plugin test-jar goal
Nonetheless, if you really want to do that, you can achieve it by setting the
testOutputDirectory like:
<build>
<testOutputDirectory>${project.build.directory}/classes</testOutputDirectory>
</build>
The Tests.java are then compiled to target/classes and from there the maven-jar-plugin packages them to the jar.
