The requested profile "test" could not be activated because it does not exist.

SpringBoot项目在执行mvn install命令时出现以下问题：

[WARNING] The requested profile "test" could not be activated because it does not exist.
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.3.RELEASE:repackage (default) on project mobile: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.3.3.RELEASE:repackage failed: Unable to find main class -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

由repackage failed: Unable to find main class可以发现是没找到主类。
但事实是SpringBoot的启动类是已经写好了的。
错误原因：
在SpringBoot描述的包中存在其它的带有main方法的类。
删除main方法即可以解决以上问题。
