[BUG][JAVA][SPRING] When using lombok generators and generatedConstructorWithRequiredArgs build fails

[dpozinen]

Description

we use the spring generator with the below config

<openapi.producer.generator.config.additionalModelTypeAnnotations.default>
    @com.fasterxml.jackson.annotation.JsonIgnoreProperties(ignoreUnknown = true)
    @lombok.Builder(toBuilder = true)
    @lombok.NoArgsConstructor
    @lombok.AllArgsConstructor
</openapi.producer.generator.config.additionalModelTypeAnnotations.default>

to generate constructors & builders.

WIth the new generatedConstructorWithRequiredArgs parameter the build fails because lombok has already generated the constructor. Then the generator attempts to do the same and fails with a constructor already exists error.

openapi-generator version

6.6.0

Suggest a fix

I think it would be best to identify already generated constructors and just ignore them, instead of failing, since ultimately there already is a suitable constructor and hence the goal is achieved.

Not Duplicate

please note I am aware of #15494 and we have applied this workaround, but in my opinion this should work out of the box. Users shouldn't have to configure another property to work around this.
