How can I fail the build on warnings?

I have the following configuration :

  <plugin>
                <groupId>io.swagger.codegen.v3</groupId>
                <artifactId>swagger-codegen-maven-plugin</artifactId>
                <version>3.0.23</version>
                <executions>
                    <execution>
                        <id>generate-models</id>
                        <goals>
                            <goal>generate</goal>
                        </goals>
                        <configuration>
                            <inputSpec>swagger.yaml</inputSpec>
                            <modelPackage>com.models</modelPackage>
                            <generateApis>false</generateApis>
                            <generateModelTests>false</generateModelTests>
                            <generateSupportingFiles>false</generateSupportingFiles>
                            <generateApiDocumentation>false</generateApiDocumentation>
                            <generateModelDocumentation>false</generateModelDocumentation>
                            <language>java</language>
                            <configOptions>
                                <dateLibrary>java8</dateLibrary>
                                <useBeanValidation>true</useBeanValidation>
                                <serializableModel>true</serializableModel>
                            </configOptions>
                        </configuration>
                    </execution>

                </executions>

            </plugin>

            <plugin>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <showWarnings>true</showWarnings>
                    <failOnWarning>true</failOnWarning>
                    <failOnError>true</failOnError>
                    <compilerArgs>
                        <arg>-Xlint:all</arg>
                        <arg>-Werror</arg>
                    </compilerArgs>
                </configuration>
            </plugin>

And in my swagger I purposely referenced an invalid value called "New type"

My goal is to fail the build when this situation happens (or any error or warning actually) but I only see a warning and my build continues as usual.

[WARNING] no property from New type

Start with the Maven plugin configuration in the issue and the referenced swagger.yaml, then trace where the generator emits the "no property from New type" warning. Determine whether that warning is expected to fail the Maven build and identify the relevant failure behavior; done means the documented invalid value causes the build to fail.
