Changing to this:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-failsafe-plugin</artifactId>
<version>2.16</version>
<configuration>
<skip>false</skip>
<includes>
<include>**/integration/**</include>
</includes>
</configuration>
<executions>
<execution>
<id>failsafe-itest</id>
<phase>integration-test</phase>
<goals>
<goal>integration-test</goal>
</goals>
<configuration>
<skip>false</skip>
<includes>
<include>**/integration/**</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
Sorted the issue.
However, I have to run the plugin itself with mvn failsafe:integration-test
in order to run integration-test only and shortcircuit the unit-tests!
