The openapi-generator-maven-plugin does not generate @ExampleObject

Question

I am using The openapi-generator-maven-plugin:6.4.0 to generate swagger code. I am able to access the APIs.

But, in generated files @ExampleObject is not present. Also, in Swagger UI I am unable to see the examples specified in inputSpec. Please suggest.

Below are the dependencies and plugins used in pom.xml file

Dependencies:

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-ui</artifactId>

</dependency>
<dependency>
    <groupId>org.openapitools</groupId>
    <artifactId>jackson-databind-nullable</artifactId>
    <version>0.2.1</version>
</dependency>

Plugin:

<plugin>
    <groupId>org.openapitools</groupId>
    <artifactId>openapi-generator-maven-plugin</artifactId>

The openapi-generator doesn't create @ExampleObject annotations. You can verify this by checking the mustache templates used to generate the objects. It sets the example using the @schema annotation instead. As for the examples not showing up in the ui, I can't help you without being able to see the input spec. Can you please share your input spec and your maven configuration? Thank you. – Abrupt

@Abrupt I have updated the question with the details – Ulm
