在使用maven插件exec-maven-plugin编译Echo服务器出现

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.6.0:java (d
efault-cli) on project zaidunduan: The parameters 'mainClass' for goal org.codeh
aus.mojo:exec-maven-plugin:1.6.0:java are missing or invalid -> [Help 1]

因为插件还没配置，注意配置引导路径

解决方法：在echo服务器的pom文件添加

<build>
    <plugins>
        <plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>exec-maven-plugin</artifactId>

                    </goals>
                </execution>
            </executions>
            <configuration>
                <mainClass>client.EchoClient</mainClass>
            </configuration>
        </plugin>
    </plugins>
</build>
