java -jar openapi-generator-cli-7.10.0.jar generate -i fern-api-archiadapter.json -g java --library webclient -c config.json ....

produce
private ResponseSpec putModelRequestCreation(UUID workspaceId, UUID modelId, OffsetDateTime tlp, File _file, UUID schemaId, String acceptLanguage, String token) throws WebClientResponseException

but File is very hard to use with dynamic content

20281

Start with the supplied multipart/form-data schema, the Java WebClient generation command, and config.json; compare the generated method signature with issue 20281. No source file or test is named, so first locate the Java WebClient generator path and clarify the intended replacement for File. Done should mean this schema generates a parameter suitable for dynamic content rather than File, with coverage for the reported case.
