Why does jetty server hangs after server start and doesn't run integration test?

Question

I am running integration test using maven-jetty-plugin and maven-failsafe-plugin. Here's my configuration:

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

        <plugin>

                        </goals>
                    </execution>
          </executions>
        </plugin>

When i run mvn clean install, jetty server starts and after that nothing happens (it gets stuck). Last line in my logs is : [INFO] Started Jetty Server. When i press control-c, here is what it prints:

2013-04-25 15:24:16.315:INFO::Shutdown hook executing

Why does it get stuck? When i press control-c, why does it perform rest of the steps? How can i fix it?

Answer 1

Try using start instead of run-war.

From javadoc on org\eclipse\jetty\jetty-maven-plugin\9.3.0.M2\jetty-maven-plugin-9.3.0.M2.jar!\org\eclipse\jetty\maven\plugin\AbstractJettyMojo.nonblocking

Determines whether or not the server blocks when started. The default behavior (false) will cause the server to pause other processes while it continues to handle web requests. This is useful when starting the server with the intent to work with it interactively. This is the behaviour of the jetty:run, jetty:run-war, jetty:run-war-exploded goals. If true, the server will not block the execution of subsequent code. This is the behaviour of the jetty:start and default behaviour of the jetty:deploy goals.

Answer 2

So in order to start the jetty add run:

<goals>
     <goal>stop</goal>
        <goal>start</goal>
</goals>

And the whole:

<plugin>
    <groupId>org.eclipse.jetty</groupId>
    <artifactId>jetty-maven-plugin</artifactId>
    <version>9.2.10.v20150310</version>

        <war>webapp/target/MyWar.war</war>
        <stopKey>fooKey</stopKey>
        <stopPort>8081</stopPort>
        <stopWait>1</stopWait>
        <httpConnector>
            <port>8888</port>
        </httpConnector>
    </configuration>
    <executions>

            <goals>
                <goal>stop</goal>
                <goal>start</goal>
            </goals>
            <configuration>
                <scanIntervalSeconds>0</scanIntervalSeconds>
                <daemon>true</daemon>
                <stopKey>STOP</stopKey>
                <stopPort>8866</stopPort>
            </configuration>
        </execution>
        <execution>

            <phase>post-integration-test</phase>
            <goals>
                <goal>stop</goal>
            </goals>
            <configuration>
                <scanIntervalSeconds>0</scanIntervalSeconds>
                <daemon>true</daemon>

        </execution>
    </executions>
</plugin>
