Description

We use the maven plugin to create our models and interfaces in spring boot.
I wanted to set an optional header parameter to a default value used on the server side. However, I can not define the string correctly. The output is always masked incorrectly with extra double quotes.

openapi-generator version

org.openapitools openapi-generator-maven-plugin 3.3.4

OpenAPI declaration file content or url

components:
    parameters:
        XConsumerId:
            in: header
            name: x-consumer-id
            description: 'filled by gateway'
            required: false
            schema:
                type: string
                default: "c1" # tried also c1 and 'c1' 
            example: c1

Generated code
@ApiParam(value = "filled by gateway" , defaultValue=""c1"") @RequestHeader(value="x-consumer-id", required=false) String xConsumerId

"" of defaultValue is not correct

Command line used for generation

Execute maven plugin

@wing328 It tried the latest "release" 4.0.0-beta2 ... but same behaviour. At the moment I only work with the maven repository and not with your github. When will you publish the next version?

[wing328]

Can you try the SNAPSHOT version instead? You can find it in the project's readme.

[zwergy88]

Snapshot versions of external maven repositories are not allowed in my company.

[karismann]

hello @pohlmarcus you can now try with release 4.0.0-beta3 and check if it is ok
