springboot 打包运行报错错误信息 Exception in thread “main“ java.lang.NoClassDefFoundError

当springboot项目有外部本地jar引用，本地idea运行正常，当打包后命令行运行，运行报以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: com/ys/product/ysmq/front/msg/AbstractConsumerMessage$ConsumerCallBack

百度了半天，才找到原因，springboot打包没有把本地jar打包进去，需要修改配置pow.xml

如下：

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>com.ydwh.gf.YdwhApplication</mainClass> <!-- 指定启动主类 -->
                    <fork>true</fork> <!-- 如果没有该配置，devtools不会生效  打包 将外部jar包打包进项目中 -->
                    <includeSystemScope>true</includeSystemScope> <!-- 打包 将外部jar包打包进项目中 -->
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                </configuration>
            </plugin>
        </plugins>
    </build>

再次打包运行，正常了
