二.错误原因
因为没有正式环境的入口类,项目结构如下:
repackage failed: Unable to find main class
pom.xml文件的<build>配置信息如下:
repackage failed: Unable to find main class
三.解决方案1
pom.xml文件的<build>中指定入口类,代码如下
<configuration>
<mainClass>com.qfx.App</mainClass>
</configuration>
如图
repackage failed: Unable to find main class
四.解决方案2
去掉<build>配置信息中spring热部署的配置，如图
repackage failed: Unable to find main class
五.解决方案3
修改pom.xml配置文件<build>内容如下,添加一个<pluginManagement>标签，代码如下
<build>
<finalName>test</finalName>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<dependencies>
<!-- spring热部署 -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>springloaded</artifactId>
<version>1.2.8.RELEASE</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</pluginManagement>
</build>
六.再次执行 Maven install,一切正常
