Jetty doesn't start in pre-integration-test phase (Maven)

Question

I'm trying to use Maven Failsafe Plugin to run my functional/integration tests, according to this guide: http://docs.codehaus.org/display/MAVENUSER/Maven+and+Integration+Testing, chapter Using the Maven Failsafe Plugin to run Integration Tests

However, jetty doesn't start in the pre-integration-test phase and thus all the tests fail. Is there any problem in the following POM configuration:

<plugin>
    <artifactId>maven-failsafe-plugin</artifactId>
    <version>2.7.1</version>
    <executions>
      <execution>
        <goals>
          <goal>integration-test</goal>
          <goal>verify</goal>
        </goals>
      </execution>
    </executions>
</plugin>

<plugin>
    <groupId>org.mortbay.jetty</groupId>
    <artifactId>maven-jetty-plugin</artifactId>
    <version>6.1.7</version>
    <configuration>

          <connectors>
            <connector implementation="org.mortbay.jetty.nio.SelectChannelConnector">

              <maxIdleTime>3600000</maxIdleTime>
            </connector>
          </connectors>

                </goals>
            </execution>
        </execution>

    </configuration>
</plugin>

I run the integration tests by mvn verify

Answer 1

I know why - first I put the execution tags inside another execution tag (instead of executions) and then this executions block shouldn't be inside configuration tag, but outside of it, right inside the plugin tag.
