【spring cloud】在spring cloud服務中，打包ms-core失敗，報錯Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.4.RELEASE:repackage (default

在spring cloud服務中，有一個ms-code專案，只為所有的微服務提供核心依賴和工具類，沒有業務意義，作為核心依賴使用。所以沒有main方法，沒有啟動類。
在spring cloud整體打包的過程中報錯：
[INFO] --- maven-jar-plugin:3.0.2:jar (default-jar) @ springcloud-ms-core --- [INFO] Building jar: D:\document\IdeaProjects\springcloud\springcloud-ms-core\target\springcloud-ms-core-0.0.1-SNAPSHOT.jar [INFO] [INFO]--- spring-boot-maven-plugin:2.0.4.RELEASE:repackage (default) @ springcloud-ms-core --- [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 3.425 s [INFO] Finished at:2018-12-07T11:09:36+08:00 [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:2.0.4.RELEASE:repackage (default) on project springcloud-ms-core: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:2.0.4.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.

提示：
錯誤原因就是沒有找到main方法，整個ms-core沒有啟動入口。
但是它作為核心依賴jar包，又沒有參與業務，所以沒有給它提供main方法的啟動類。
解決方法：
新增一個spring boot的啟動類，新增一個main方法作為程式入口。
@SpringBootApplication
public class SpringCloudMsCoreApp {
public static void main(String[] args) {
SpringApplication.run(SpringCloudMsCoreApp.class, args);
}
}
重新打包即可！！！
