How to choose which JUnit5 Tags to execute with Maven

Question

I have just upgraded my solution to use JUnit5. Now trying to create tags for my tests that have two tags: @Fast and @Slow. To start off I have used the below maven entry to configure which test to run with my default build. This means that when I execute mvn test only my fast tests will execute. I assume I can override this using the command line. But I can not figure out what I would enter to run my slow tests....

I assumed something like.... mvn test -Dmaven.IncludeTags=fast,slow which does not work

<plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.19.1</version>
    <configuration>
        <properties>
            <includeTags>fast</includeTags>
            <excludeTags>slow</excludeTags>
        </properties>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.junit.jupiter</groupId>
            <artifactId>junit-jupiter-engine</artifactId>
            <version>5.0.0-M3</version>
        </dependency>
        <dependency>
            <groupId>org.junit.platform</groupId>
            <artifactId>junit-platform-surefire-provider</artifactId>
            <version>1.0.0-M3</version>
        </dependency>
    </dependencies>
</plugin>

You can use this way:

<properties>
    <tests>fast</tests>
</properties>

<profiles>
    <profile>
        <id>allTests</id>
        <properties>
            <tests>fast,slow</tests>
        </properties>
    </profile>
</profiles>

<build>
    <plugins>
        <plugin>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>3.0.0-M5</version>
            <configuration>
                <groups>${tests}</groups>
            </configuration>
        </plugin>
    </plugins>
</build>

This way you can start with mvn -PallTests test all tests (or even with mvn -Dtests=fast,slow test).
