英文:
Can't build image of war file using mvn spring-boot:build-image
问题
以下是翻译好的内容：
我正在尝试使用 Spring Boot 的 build-image 目标来构建我的项目的 Docker 镜像（该项目被打包为 war 文件，而不是 jar 文件），但我遇到了这个错误：
Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:2.3.3.RELEASE:build-image failed: Source must refer to an existing file, got E:\my_project\Java\Workspace\demo\target\demo-0.0.1-SNAPSHOT.jar
这是我用来构建镜像的命令：
mvn spring-boot:build-image -Dspring-boot.build-image.imageName=projectio/demo
这是我的 pom 文件：
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.3.3.RELEASE</version>

插件似乎在寻找一个 jar 文件，但我正在构建一个 war 文件，我该如何解决这个问题？
英文:
I'm trying to build a Docker image to my project (which is packaged to war file, not jar file) using Spring Boot build-image goal and I got this error
Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:2.3.3.RELEASE:build-image failed: Source must refer to an existing file, got E:\my_project\Java\Workspace\demo\target\demo-0.0.1-SNAPSHOT.jar
This the command which I used to build the image
mvn spring-boot:build-image -Dspring-boot.build-image.imageName=projectio/demo
And this is my pom file
<modelVersion>4.0.0</modelVersion>

The plugin seems to search for a jar file and I'm building a war file how can I fix this?

当前版本的Spring（2.3.5）不支持使用mvn spring-boot:build-image或gradle bootBuildImage来构建war文件类型的镜像。
他们已决定在2.5X版本中添加这个功能。下面的里程碑链接详细介绍了此事。

英文:
The current version of spring(2.3.5) does not support to build an image of a war file type using mvn spring-boot:build-image or gradle bootBuildImage.
They have decided to add this feature to 2.5X release. The below milestone link has detail about the same.

你可以尝试将打包方式从war更改为jar
<packaging>jar</packaging>

You can try changing packaging from war to jar
<packaging>jar</packaging>
