Customizing client code generation

Sometimes you don't want the codegen to make a model for you--you might want to just include one that already exists in your codebase. Say you already have a User object and want to reuse that, which has a different model package from the other generated files:

First, indicate that the class is already included by default. This will keep the codegen from trying to generate the class.

--language-specific-primitives=Pet

This command line option will tell the generator to consider Pet a "primitive" type.

Next, if the Pet class is a different package, add an --import-mapping to tell the generator to include that import wherever Pet is used:

--import-mappings=Pet=com.yourpackage.models.Pet

Now the codegen will know what to import from that specific package.

NOTE: import-mappings is assigned a key-value pair in this example, but multiple values can be comma-separate. For instance:

--import-mappings=Pet=com.yourpackage.models.Pet,User=com.yourpackage.models.User
