Maven shade plugin fails on updating Spring Boot version to 2.4.0 from 2.3.3

Question

I just updated the Spring Boot version in my project from 2.3.3 to 2.4.0.

For a module in my project I use maven-shade-plugin with a simple shade goal, no configuration. When I was using Spring Boot 2.3.3 everything went well. With this update to 2.4.0 seems like it asks me for an configuration which I cannot load.

I did this required configs from this post But it didn't help me.

Here is what I have now.

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
    <dependencies>
        <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>2.4.0</version>
    </dependency>
    </dependencies>
    <executions>
        <!-- Run shade goal on package phase -->
        <execution>
            <phase>package</phase>
            <goals>
                <goal>shade</goal>
            </goals>
            <configuration>
                <transformers>
                    <transformer
                            implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.handlers</resource>
                    </transformer>
                    <transformer
                            implementation="org.springframework.boot.maven.PropertiesMergingResourceTransformer">
                        <resource>META-INF/spring.factories</resource>
                    </transformer>
                    <transformer
                            implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                        <resource>META-INF/spring.schemas</resource>
                    </transformer>
                    <transformer
                            implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin>

I don't have a main class because this module behaves like a client (swagger generated stuff).

The error when I build with maven is the following:

Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.1:shade (default) on project zenzefi-client: Unable to parse configuration of mojo org.apache.maven.plugins:maven-shade-plugin:3.2.1:shade for parameter transformers: Cannot load implementation hint 'org.springframework.boot.maven.PropertiesMergingResourceTransformer'

What am I missing?
