[BUG][Maven] importMappings not working

See original GitHub issue

maven plugin is not working as expected when trying to use an already existing class.

Here (https://openapi-generator.tech/docs/usage#target-external-models) are the instructions to generate code using a existing class.

It works when using openapi-generator client. When I execute this

openapi-generator generate \
    -i https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml \
    -g java \
    -o out \
    --language-specific-primitives=Pet \
    --import-mappings=Pet=com.yourpackage.models.Pet

Then Pet.java, as expected, does not exist in src/main/java/org/openapitools/client/model/

But when doing the same with maven plugin

<plugin>
        <groupId>org.openapitools</groupId>
        <artifactId>openapi-generator-maven-plugin</artifactId>
        <version>4.2.2</version>
        <executions>
                <execution>
                        <goals>
                                <goal>generate</goal>
                        </goals>
                        <configuration>
                                <inputSpec>https://raw.githubusercontent.com/OAI/OpenAPI-Specification/master/examples/v3.0/petstore.yaml</inputSpec>
                                <generatorName>java</generatorName>
                                <configOptions>
                                    <languageSpecificPrimitives>Pet</languageSpecificPrimitives>
                                    <importMappings>Pet=com.yourpackage.models.Pet</importMappings>
                                </configOptions>
                        </configuration>
                </execution>
        </executions>
</plugin>

Then Pet.java does exist in src/main/java/org/openapitools/client/model/ but it shouldn’t

openapi-generator-maven-plugin 4.2.2 openapi-generator-cli 4.2.1

Many thanks @uortiz, that was pretty hidden

I wonder if it’s possible to make this change clear in the documentation or to show some kind of warning when generating sources.

Also, I don’t really get this “backwards-compatibility” if it won’t work. I think it’s preferable to show an error instead of not complaining at all but also do nothing, it’s confusing.

Anyways, thanks again
