异常：Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.3.2.RELEASE:repackage (repackage) 解决办法

异常：Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.3.2.RELEASE:repackage (repackage) on project microblog-util: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.3.2.RELEASE:repackage failed: Unable to find main class

解决方法：注释掉父项目中的build（因为子项目中有模块不存在main启动类）
