Description

I had a simple openApiGenerate task working.
I tried to upgrade my gradle version from 6.8.3 to 7.2 and also the org.openapi.generator gradle plugin version from 5.0.0 to 5.2.1

Error message :

class com.fasterxml.jackson.core.JsonFactoryBuilder tried to access private field com.fasterxml.jackson.core.JsonFactory.DEFAULT_ROOT_VALUE_SEPARATOR

Full error message :

openapi-generator version

On version 5.0.0 I got an annotation issue that has already been fixed.
Upgraded to version 5.2.1 I got the new jackson error.

I found the same error message in : https://github.com/OpenAPITools/openapi-generator/issues/5004

Suggest a fix

Fix looks like to be on Jackson libs dependencies.

Start with the build.gradle openApiGenerate configuration and the Gradle plugin versions 5.2.1 and 7.2; reproduce the failure with the provided schema.yml using gradlew openApiGenerate. Trace the Jackson dependency versions involved in the JsonFactoryBuilder access error and compare with related issue #5004. Done means the task completes without this error.
