Answer 1

You are getting this error because the jetty plugin prefix is not recognized by default (as part of default plugins) nor configured in your settings.

Change the build section you mentioned as below (that is, add the Jenkins Maven Plugin to it):

<build>
    <finalName>springmvc_googlechart</finalName>
    <plugins>
        <plugin>
            <groupId>org.eclipse.jetty</groupId>
            <artifactId>jetty-maven-plugin</artifactId>
            <version>9.2.8.v20150217</version>
            <configuration>
                <scanIntervalSeconds>10</scanIntervalSeconds>
                <httpConnector>
                    <port>7777</port>
                </httpConnector>
            </configuration>
        </plugin>
    </plugins>
</build>

By defining the Jetty Maven Plugin as part of your POM, Maven will properly recognize the jetty prefix/alias from command line, hence executing the following will work:

mvn jetty:run

Note: in the configuration above, Jetty will run on port 7777 (hence, accessible from http://localhost:7777), you can change it as required. By default the application will be deployed under the server root (the URL previously mentioned). If you want to access it from http://localhost:7777/springmvc_googlechart, you can then add the following to the above configuration section:

<webApp>
    <contextPath>/${project.build.finalName}</contextPath>
</webApp>

Check the official plugin documentation for further configuration.
