使用springboot+maven出现的问题

问题描述：
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][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

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
