我试图从我的Sping Boot 项目创建一个映像，我想创建一个Dockerfile，它可以创建我的项目的映像。
经过几次谷歌搜索，我从官方文档中找到了这个教程。
所以我试着创建一个基于它的文件，这是我得到的：

FROM openjdk:17-jdk-alpine
COPY out/artifacts/DWH_WebServices_jar/DWH_WebServices.jar app.jar
EXPOSE 8080
ENTRYPOINT ["java", "-jar", "/app.jar"]

但是当使用Intellij运行DockerFile时，我收到以下错误：

Error: Could not find or load main class com.business.dwh_webservices.DwhWebServicesApplication
Caused by: java.lang.ClassNotFoundException: com.business.dwh_webservices.DwhWebServicesApplication

所以我想，在创建.JAR时，我可能给类提供了错误的信息，但我做得很正确：

我的类存在如下所示：

这是我的pom.xml：

我做错了什么？
