在maven进行jetty的调试中出现错误：

[ERROR] No plugin found for prefix 'jetty' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\Documents and Settings\Administrator\.m2\repository), central (http://repo.maven.apache.org/maven2)] -> [Help 1][ERROR][ERROR] To see the full stack trace of the errors, re-run Maven with the -e swit

详情如下：

settings.xml没有配置插件应此需要

<span style="background-color: rgb(255, 0, 0);">mvn org.mortbay.jetty:maven-jetty-plugin:run </span>

这样来运行。
如果需要使用jetty:run,那么必须在maven的setting.xml下配置

<pluginGroups>    <pluginGroup>org.mortbay.jetty</pluginGroup>  </pluginGroups>

或者在对应项目的pom.xml中plugins的节点下添加配置

<plugin>                <groupId>org.mortbay.jetty</groupId>                <artifactId>jetty-maven-plugin</artifactId>                <configuration>                    <webApp>                        <contextPath>/</contextPath>                    </webApp>                    <stopKey>webx</stopKey>                    <stopPort>9999</stopPort>                    <connectors>                        <connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">                            <port>8081</port>                            <maxIdleTime>60000</maxIdleTime>                        </connector>                    </connectors>                    <requestLog implementation="org.eclipse.jetty.server.NCSARequestLog">                        <filename>target/access.log</filename>                        <retainDays>90</retainDays>                        <append>false</append>                        <extended>false</extended>                        <logTimeZone>GMT+8:00</logTimeZone>                    </requestLog>                    <systemProperties>                        <systemProperty>                            <name>productionMode</name>                            <value>${productionMode}</value>                        </systemProperty>                    </systemProperties>                </configuration>            </plugin>

PS：jetty官网的教程感觉有点坑！只让添加plugin，然后就mvn jetty：run了。。。 E文不好的孩子伤不起。。。。
