please add a 'mainClass’ property

when build an spring project with this command:

mvn spring-boot:run

there will may show an error message like this:

Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.2.5.RELEASE:run (default-cli) on project gs-rest-service: Unable to find a suitable main class, please add a 'mainClass’ property

ok,i was bothering by this case...so,,,google..google..and find this web page:

http://docs.spring.io/autorepo/docs/spring-boot/1.2.4.RELEASE/maven-plugin/usage.html

And ,this is the Solution(the bold part)

<plugin>

　　<groupId>org.springframework.boot</groupId>

　　<artifactId>spring-boot-maven-plugin</artifactId>

　　<configuration>

　　　　<mainClass>class_name</mainClass>

　　</configuration>

</plugin>
