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

本文解决了一个SpringBoot项目中使用mvn install命令时遇到的问题:找不到主类。问题原因是项目中存在多个带有main方法的类,解决方法是删除多余的main方法。

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.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.
[ERROR] 
[ERROR] For more information about the errors and possible solutions, please read the following articles:
[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginExecutionException

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。
