How to call generator with deprecated D arguments?

[Pe-te]

Hi folks, when I run the following command:

export JAVA_OPTS="${JAVA_OPTS} -Dlog.level=warn"
openapi-generator generate -g kotlin -D models -D apis --library jvm-retrofit2 -i "${YAML_FILE}" -o "${KOTLIN_PATH}" --additional-properties=serializationLibrary=gson

I get this deprecation message:

[DEPRECATED] -D arguments after 'generate' are application arguments and not Java System Properties, please consider changing to -p, or apply your options to JAVA_OPTS, or move the -D arguments before the jar option.

I tried different combinations and positions and couldn't get rid of it. What would be the correct way to call the generator?

macOS, homebrew, openapi-generator 4.2.3

@Pe-te sorry, that message was intended for users who used -D to pass system properties. It wasn't very clear for users using it for -Dapis or other "global properties" like you have.

I've opened #5687 to add --global-property as the long form alongside the -D short property. This should clear up usage as well as finalizing the removal of confusing around the -D property, which is slated for removal in 5.0.

Thanks for the quick reply!

I'm just still a little confused what I should do now:

• Is it okay/correct to use the -D until the --global-property is implemented or do I need a different mechanism to pass the api and model parameters?

• Could the --global-property also somehow be used to set the log level so we don't need to modify the JAVA_OPTS? or is this possible somehow else?

[jimschubert]

@Pe-te The log level can only be set as a Java System Property, so it'll need to stay the same.

You can continue using the -D for generator global properties like apis and models until the change is released in 4.3.0, this will give you time to switch before -D is removed in 5.0.

Okay, I see. Thanks again!
