Spring Boot Cloud Native Buildpacks on Heroku?

I configured my Spring Boot project to use cloud Native Buildpacks to build its docker image as below:

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <image>
                    <name>my-image</name>
                </image>
            </configuration>
        </plugin>
    </plugins>
</build>

The resulting Docker image works fine, but I would like to deploy it on Heroku. I pushed it to the Heroku Container Registry and tried to release it as explained below:

• https://devcenter.heroku.com/articles/container-registry-and-runtime#building-and-pushing-image-s
• https://devcenter.heroku.com/articles/container-registry-and-runtime#releasing-an-image

When I run:

heroku container:release web --app my-app

I get the following error:

▸    Expected response to be successful, got 404

By googling the error, it seems that it is due to the fact that the resulting Docker image uses ENTRYPOINT instead of CMD to start the application, as explained in the links below:

• https://github.com/grandnode/grandnode/issues/563
• https://github.com/heroku/cli/issues/1081
• https://devcenter.heroku.com/articles/container-registry-and-runtime#dockerfile-commands-and-runtime

Is it possible to configure the Spring Boot Buildpack in order to use CMD instead of ENTRYPOINT? Or any other solution to deploy the resulting Docker image on Heroku?
