How do I install a test-jar in maven?

I have a test-jar which I would like to install. I am not sure if there is a different way to install test-jars, such as defining a property that tells maven it is a test-jar.

Also, the groupId and artifactId are the same as another jar for which the test is made from.

So far this is how my install command looks like:

mvn install:install-file -DgroupId=com.example -DartifactId=example -Dpackaging=jar -Dversion=1.2.3 -Dfile=example-test.jar -DgeneratePom=true

So how exactly would I install a test jar? I know there has to be something to tell maven it is a test-jar since the groupId and artifactId is the same as another jar(which would be the jar that example-test.jar is a test of).

You don't need to install them manually. Maven will do this for you when executing:

mvn clean install

You need a configuration along the lines of:

    ...
    <build>
       <plugins>
           <plugin>
               <groupId>org.apache.maven.plugins</groupId>
               <artifactId>maven-jar-plugin</artifactId>
               <version>2.2</version>

               <executions>
                   <execution>
                       <goals>
                           <goal>test-jar</goal>
                       </goals>
                   </execution>
               </executions>
           </plugin>
        </plugins>
    </build>
    ...

Then, later on in your other module where you'll need to use it, you need to define the dependency's type as:

 <dependency>
    <groupId>com.foo</groupId>
    <artifactId>bar</artifactId>
    <version>1.2.3</version>
    <type>test-jar</type>
    <scope>test</scope>
 </dependency>

mvn install:install-file 
    -DgroupId=com.example 
    -DartifactId=example 
    -Dversion=1.2.3 
    -Dclassifier=tests 
    -Dpackaging=test-jar 
    -Dfile=example-1.2.3-tests.jar

You put your test code in the same project as your normal code, under /src/test/java. Maven takes care of not including the test code in the packaged jar. If you have dependencies that are only used for unit testing (e.g. mockito, junit, etc) then you give them a scope of "test" in the maven dependencies and they'll be available to the unit tests but not included in the actual jar.

I guess you might have missed the generatePom flag, i got the same error but finally the below worked

mvn install:install-file 
    -Dfile=c:/primo/primo-1.0.0-SNAPSHOT.jar 
    -DgroupId=uk.bl.primo 
    -DartifactId=primo 
    -Dversion=1.0.0 
    -Dpackaging=jar 
    -DgeneratePom=true
