Can't build image of war file using mvn spring-boot:build-image

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>
<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.3.RELEASE</version>
    <relativePath/>
</parent>
<groupId>com.pdr</groupId>
<artifactId>demo</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>war</packaging>
<name>demo</name>

<properties>
    <java.version>1.8</java.version>
</properties>

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
        <exclusions>
            <exclusion>
                <groupId>org.junit.vintage</groupId>
                <artifactId>junit-vintage-engine</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

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

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.

You can try changing packaging from war to jar

<packaging>jar</packaging>
