很棘手？springboot项目要求maven打包即运行，又依赖？

在真实场景中，一般项目打包要么是可运行jar、要么是不可运行jar也就是依赖jar，但也不可否认存在一些伪分布式单体项目，要求依赖子项目的情况，那就会存在又要运行，又要依赖，怎么办？

莫慌，我来帮你！

找到即要求打包又要求依赖的项目的pom文件，在最底行加入如下配置即可。

    <build>
        <finalName>xxxxx</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <classifier>exec</classifier>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

这段配置中真正帮你解决问题的是 <classifier> 标签，classifier 通常用于区分从同一POM构建的具有不同内容的构建。

补上打包后的截图

无视 javadoc 与 sources，打包后的jar有俩个，service 包为依赖包，exec为可执行包。

附: 父项目的打包配置。
