How to use Maven Surefire plug-in with different groups for test and integration-test?

Question

I want to use testng with the Surefire plug-in of Maven. The idea is to tag some tests with a group integrationTest and run the plug-in twice: for goal test excluding the group integrationTest and for goal integration-test including the group integrationTest only.

I found some material for running the plug-in for both goals and that works, but the group for the second run does not work (no test is executed).

Here is the plug-in configuration in the build element of my pom.xml:

  <plugin>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
      <excludedGroups>integrationTest</excludedGroups>
      <reportFormat>brief</reportFormat>
      <trimStackTrace>true</trimStackTrace>
      <useFile>false</useFile>
    </configuration>
    <executions>
      <execution>
        <id>integration-test</id>
        <phase>integration-test</phase>
        <goals>
          <goal>test</goal>
        </goals>
        <configuration>
          <groups>integrationTest</groups>
          <excludedGroups/>
          <reportsDirectory>${project.build.directory}/surefire-reports/integration</reportsDirectory>
        </configuration>
      </execution>
    </executions>
  </plugin>

Any idea? mvn integration-test runs all unit tests as expected (excluding the group integrationTest) but the second test run just writes:

Running TestSuite
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.562 sec

The Result of mvn test is as expected, tests run and group integrationTest is ignored.

I got it - irritating configuration implementation!

<excludedGroups/> does not override <excludedGroups>integrationTest</excludedGroups>. You need to specify any (unknown) group instead, <excludedGroups>none</excludedGroups> for example.
