Java Spring boot maven插件即使在I'；我提到了mainClass属性及其'；就在它下面'；鼻子

我有一个父项目“giftcard服务”，我只用于构建它。所有代码都在名为“giftcard service main”的模块中。我能够构建（

clean install

）giftcard服务，但无法部署/运行它，这是通过

mvn-spring-boot:run

命令完成的

由于这是一个企业/公司项目，我会出于明显的原因限制一些信息

这是我在控制台上看到的错误

我不确定，但怀疑这意味着当您试图执行
mvn spring boot:run
时，您在父项目的目录中。我认为您需要在子项目中，主类实际上属于该子项目。
请显示完整的pom文件…这看起来很奇怪
