1. jib-maven-plugin打包报错:

Cannot find default setter in class com.google.cloud.tools.jib.maven.JibPluginConfiguration$FromConfiguration

原因 : from标签设置不对,改成这种格式(新版本是这样的)

<from>
    <image>ascdc/jdk8</image>
</from>

2.再次报错:没有定义mainclass

报错日志:

Failed to execute goal com.google.cloud.tools:jib-maven-plugin:3.2.1:build (default-cli) on project ruoyi-system: Multiple valid main classes were found: xyz.xxdl.life.service.impl.LifeElectricityHi
sServiceImpl, xyz.xxdl.utils.EmailUtils, perhaps you should add a `mainClass` configuration to jib-maven-plugin

解决

 <container>
                        <mainClass>xyz.xxdl.RuoYiApplication</mainClass>
                    </container>

3. 完整配置

   <plugin>
                <groupId>com.google.cloud.tools</groupId>
                <artifactId>jib-maven-plugin</artifactId>
