问题描述：springBoot 多项目在 idea 中可以正常启动，打包时报错找不到类，如下图

分析：从 zuul 以上模块都可以打包成功，以下模块都失败因为都依赖了 callcenter-common，却找不到的类
百思不得其姐
解决： 给被依赖的模块 pom.xml 中增加如下: 打包成非可执行的 jar
<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> <configuration> <classifier>exec</classifier> </configuration> </plugin> </plugins> </build>
