--------------------

## 原因分析： ##

原因是添加该插件后编译打包时会自动寻找项目中的启动类，如果某个模块没有启动类或者有多个main启动类就会报错，通过保证模块启动类main启动类入口唯一也可以解决。

## 解决方案： ##

<plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
              
              <mainClass>com.test.ApplicationMain</executable>
            </configuration>
            <executions>
              <execution>
                <goals>
                    <goal>repackage</goal>
                </goals>
              </execution>
            </executions>
          </plugin>
