How to have multiple versions of @SpringBootApplication main classes in multi release jar?

I am having 2 different versions of spring config pertaining to 2 different versions of java i.e java 8 and java 11

the project structure is something like :

pom.xml :

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

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

    <plugins>
        <plugin>

                    </jdk>
                </toolchains>
            </configuration>
            <executions>

            </executions>

                    <configuration>
                        <release>8</release>
                    </configuration>
                </execution>
                <execution>
                    <id>compile-java-11</id>
                    <phase>compile</phase>
                    <goals>

                    </goals>
                    <configuration>
                        <release>11</release>
                        <compileSourceRoots>
                            <compileSourceRoot>${project.basedir}/src/main/java11</compileSourceRoot>
                        </compileSourceRoots>
                        <multiReleaseOutput>true</multiReleaseOutput>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>

            <configuration>
                <archive>
                    <manifestEntries>
                        <Multi-Release>true</Multi-Release>
                    </manifestEntries>

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

but upon building the project, the build fails with following reason

[INFO] ------------------------------------------------------------------------
[INFO] BUILD FAILURE
[INFO] ------------------------------------------------------------------------

le to find a single main class from the following candidates [com.example.demo.DemoApplication, META-INF.versions.11.com.example.demo.DemoApplication] -> [Help 1]
[ERROR]

So, is there any way to use two classes without getting this build failure?

Also, I cannot use profiles and mention class to be used in a specific profile.
