Answer 1

您收到此错误是因为jetty插件前缀为not recognized by default（作为默认插件的一部分），也未在您的设置中配置。

更改您提到的build部分，如下所示（即将Jenkins Maven插件添加到其中）：

<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>

通过将Jetty Maven插件定义为POM的一部分，Maven将从命令行正确识别jetty前缀/别名，因此执行以下操作将起作用：

mvn jetty:run

注意：在上面的配置中，Jetty将在端口7777上运行（因此可以从http://localhost:7777访问），您可以根据需要进行更改。默认情况下，应用程序将部署在服务器根目录下（前面提到的URL）。如果您想从http://localhost:7777/springmvc_googlechart访问它，则可以将以下内容添加到上面的configuration部分：

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

检查official plugin documentation以进一步配置。
