我maven項目結構如下：

pom.xml內容如下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

                </configuration>
            </plugin>
        </plugins>
    </build>


</project>

maven打包後的結果：
