The javac linter has a number of warnings that are really off-the-wall, and you can't turn them off individually. This is one of them. I'd suggest using a different linter.

You can't turn off this specific warning, you can only turn off all annotation processor warnings with the -processing flag to -Xlint , eg.

-Xlint:all,-serial,-processing

in Maven:

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>${maven.compiler.source}</source>
                <target>${maven.compiler.target}</target>
                <showWarnings>true</showWarnings>
                <compilerArgs>
                    <!-- We turn off:
                        - `serial` because we don't use Java serialization 
                          (and all it does is stupidly complain about the serialVersionUID)
                        - `processing` because it complains about every annotation
                    -->
                    <arg>-Xlint:all,-serial,-processing</arg>
                </compilerArgs>
            </configuration>
        </plugin>

You can see all the warnings that will be disable by searching for "warn.proc" in compiler.properties . You can see all linter options with javac --help-lint .
