在Maven依赖项中指定jar和test-jar类型

Question

I have a project called "commons" that contains common includes for both runtime and test.

In the main project I added a dependency for commons:

    <dependency>
        <groupId>com.alexb</groupId>
        <artifactId>commons</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>

However the test common files are not included. So I added :

    <dependency>
        <groupId>com.alexb</groupId>
        <artifactId>commons</artifactId>
        <version>1.0-SNAPSHOT</version>
        <type>test-jar</type>       
    </dependency>

However when type is test-jar, the runtime is not included.

Unfortunatelly, it seems I cannot include both:

<type>jar,test-jar</type>       

What can I do to include both?

As @khmarbaise mentioned in the comments you should separate your test-jar part project.

I presume you have in the commons pom.xml something like this which generates common test-jar.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>3.1.1</version>
    <executions>
      <execution>
        <goals>
          <goal>test-jar</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

The problem with this approach is that you don't get the transitive test-scoped dependencies automatically.
