❌ Docker构建镜像错误
Failed to execute goal com.spotify:docker-maven-plugin:1.0.0:build (default-cli) on project boot-docker-demo: Exception caught: ADD failed: file not found in build context or excluded by .dockerignore: stat spring-boot-docker-1.0.jar: file does not exist -> [Help 1]
错误原因： pom.xml中jar文件配置出错没有添加后缀.jar
解决办法：
保证项目文件pom.xml中配置正确以及Dockerfile中文件名是可达的
