Compatibility with exclusiveMinimum in OpenAPI 3.0.0 vs. 3.1.0

[raichuchuchu]

We've encountered an issue when using openapi-generator with an OpenAPI specification that utilizes exclusiveMinimum for number properties. Specifically, the syntax for exclusiveMinimum differs between OpenAPI Specification 3.0.0 and 3.1.0, and openapi-generator currently only seems to support the 3.0.0 syntax.

In our file, for a property like PriceDTO.originalPrice, we need to define exclusiveMinimum.

OpenAPI 3.0.0 syntax for exclusiveMinimum:

type: number
exclusiveMinimum: true
minimum: 0

OpenAPI 3.1.0 syntax for exclusiveMinimum (as per specification):

type: number
exclusiveMinimum: 0

When our openapi.yaml uses the 3.1.0 style for exclusiveMinimum, openapi-generator fails to correctly process the schema, leading to generation errors or incorrect model definitions.

We would like to inquire if there are plans to update openapi-generator to fully support the OpenAPI 3.1.0 syntax for exclusiveMinimum, or if there's a recommended workaround for this compatibility issue.

This issue impacts our ability to seamlessly upgrade our OpenAPI specifications to 3.1.0 while continuing to use openapi-generator for client/server code generation.

thanks for opening an issue

we definitely want to support the OpenAPI 3.1.0 syntax for exclusiveMinimum.

would you like to sponsor the enhancement or contribute a PR instead?

[raichuchuchu]

Thank you for your prompt response and for considering our suggestion. We appreciate your willingness to support the OpenAPI 3.1.0 syntax for exclusiveMinimum.

For our current project, we have decided to temporarily proceed with OpenAPI 3.0.0 due to existing constraints. As such, we do not have immediate plans to sponsor the enhancement or contribute a Pull Request at this time.

We will definitely keep this in mind for future considerations and appreciate your community's efforts.

Hi, I found the issue a few days ago as I was looking for something to contribute to OpenSource
I just pushed my fix, but I didn't see that @raichuchuchu did want to solve the issue. Should I delete my PR?
