swagger-codegen-maven-plugin server code generation

[chandresh87]

I am trying to generate the server code using swagger-codegen-maven-plugin but it is generating the code with swagger 1.5 annotations like @ApiModel and @ApiModelProperty and not using @Operation & @Schema.

I am using the following config and dependencies in pom:

<plugin>
            <!-- code gen start -->
            <groupId>io.swagger.codegen.v3</groupId>
            <artifactId>swagger-codegen-maven-plugin</artifactId>

            <executions>

                    <goals>
                        <goal>generate</goal>
                    </goals>
                    <configuration>
                        <inputSpec>${project.basedir}/src/main/resources/openapi/${project.name}.yml</inputSpec>

                        <invokerPackage>${client.base.package.name}.invoker</invokerPackage>-->

                        <modelPackage>${project.groupId}.generated.model</modelPackage>

It appears that the swagger-codegen-maven-plugin 3.0.26 generates the Swagger 3 annotations.
