Maven使用package打包Spring Boot时出现:Unable to find a single main class from the following candidates的问题解决

问题如下:

[ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.5.RELEASE:repackage (default) on project information: Execution default of goal org.springframework.boot:spring-boot-maven-plugin:1.3.5.RELEASE:repackage failed: Unable to find a single main class from the following candidates [com.hhly.InformationApplication, com.hhly.test.Application] -> [Help 1]

解决方法:

这个错误是因为Maven在执行打包的时候会查找项目中的main方法,并设置为Spring Boot生成JAR包的启动入口,但此时有多个main方法,Maven插件就无法确认是用哪个。因此出现此异常。

1、注释掉其他无用的main方法即可解决此问题。

2、在命令上指定入口:

mvn package -Dstart-class=com.jsoft.MainClass
