This issue is with gradle plugin. After upgrading it from 5.1.1 to 5.2.0 i have this error while trying to generate models:

* What went wrong:
Execution failed for task ':apimodels:generateKotlinModels'.
> 'com.fasterxml.jackson.core.util.JacksonFeatureSet com.fasterxml.jackson.core.JsonParser.getReadCapabilities()'

* Try:
Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Exception is:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':apimodels:generateKotlinModels'.

openapi-generator version

5.2.0. Downgrading to 5.1.1 fixes the issue

OpenAPI declaration file content or url

Unfortunately i cannot provide swagger file due to client policies. But since this is a regression and seems to be connected to jackson dependency i don't think the declaration is necessary.

Research direction

Start by reproducing :apimodels:generateKotlinModels with Gradle plugin 5.2.0 and trace the failure from GenerateTask.doWork through CodegenConfigurator and OpenAPIV3Parser. Compare dependency resolution with plugin 5.1.1, focusing on the Jackson classes named in the stack trace. Done means model generation completes without the NoSuchMethodError.
