Description

I override the type array from java.util.List to java.util.Collection. This works perfectly fine for input arguments. However, when only the return class of the interface method is a Collection the import is not added.

pom.xml

                    <typeMappings>array=Collection</typeMappings>
                    <importMappings>
                        <importMapping>Collection=java.util.Collection</importMapping>
                    </importMappings>

generatedResource.java

Hi, did you use the java generator, or a different one?

Hi @martin-mfg,
I used the jaxrs-spec generator
