springboot 在执行maven install 时候出现以下错误
[INFO] ------------------------------------------------------------------------
[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.4.2.RELEASE:repackage (default) on project springcloud-common: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.4.2.RELEASE:repackage failed: Unable to find a single main class from the following candidates [com.itmuch.cloud.common.Application, com.itmuch.cloud.common.utils.SmsUtils] -> [Help 1]

解决办法:
1、在pom.xml文件中加入主类,用于指定加载的主类(在properties中,加入一个start-class的属性,用于告诉spring boot maven plugin哪个类是入口类即可)
<properties>
<start-class>com.itmuch.cloud.common.Application</start-class>
</properties>
2、在build中添加如下配置
<build>
...
<plugins>
...
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>1.4.0.RELEASE</version>
<configuration>
<mainClass>${start-class}</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
...
</plugins>
...
</build>
最好执行maven install即可
