Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.11.0:compile (default-compile)

Question

I am encountering an error when trying to build my Maven project. The build fails with the following error message:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.11.0:compile (default-compile) on project Blinknotes: Fatal error compiling: invalid flag: --release -> [Help 1]

Here's the full error output:

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

i tried:

Verified JAVA_HOME and PATH environment variables point to the correct JDK 19 installation. Ran mvn clean install and mvn clean install -X for debug logging. Cleaned local repository with mvn dependency:purge-local-repository

How can I resolve the invalid flag: --release error during the Maven build process? Is there a specific configuration or step I am missing?
