项目结构图如下：

在SpringBoot多模块项目打包时遇见如下错误：

1、repackage failed: Unable to find main class -> [Help 1]

解决步骤：

（1）删除父pom中的build标签

（2）在web模块的pom中配置，指定启动类，其他模块中不需要配置：

<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>com.dh.yjt.SpringBootDemo.SpringBootDemoApplication</mainClass>
</configuration>
</plugin>
</plugins>
</build>

2、[ERROR] /xxx.java:[16,39] 程序包com.xx..xxx不存在

解决办法：删除其他模块中的build标签

3、springboot打包与配置文件外置

最终pom及package文件如下：
