SpringBoot在install时报错Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.3.9.

我的SpringBoot项目，将一个子模块common在install时报错：

 Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.3.9.RELEASE:repackage (repackage) on project u-common: Execution repackage of goal org.springframework.boot:spring-boot-maven-plugin:2.3.9.RELEASE:repackage failed: Unable to find main class

根据Unable to find main class猜测原因是子模块中没有启动类，而父项目的pom.xml中有spring-boot-maven-plugin，导致报错，果然，将这段代码注释掉后就install成功。
