[BUG] Jaxrs-Jersey produces server that doesn't compile + doesn't handle parent tag in pom.xml correctly

[robbieheywood]

Description

I've been testing out openapi-generator but have come up against a few issues, which I've repro'd using the petstore example found at https://github.com/OAI/OpenAPI-Specification/blob/master/examples/v3.0/petstore.yaml. I've been trying out server generation by running openapi-generator generate -i petstore.yaml -g jaxrs-jersey -o server, but have encountered the following issues:

1. After generation, when I run mvn clean package jetty:run as instructed by the generated README, I get the following compilation error:

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] ~/repos/OpenAPI-Specification/examples/v3.0/server/src/gen/java/org/openapitools/api/ApiResponseMessage.java:[3,33] package javax.xml.bind.annotation does not exist
[ERROR] ~/repos/OpenAPI-Specification/examples/v3.0/server/src/gen/java/org/openapitools/api/ApiResponseMessage.java:[5,27] package javax.xml.bind.annotation does not exist
[ERROR] ~/repos/OpenAPI-Specification/examples/v3.0/server/src/gen/java/org/openapitools/api/ApiResponseMessage.java:[45,6] cannot find symbol
  symbol:   class XmlTransient
  location: class org.openapitools.api.ApiResponseMessage

2. If I run the generation step with openapi-generator generate -i petstore.yaml -g jaxrs-jersey -o server --additional-properties=parentArtifactId=parent-artifact,parentGroupId=parent-group,parentVersion=1.0-SNAPSHOT, then I don't see any parent tag in the generated pom.xml (as expected after reading the docs at https://openapi-generator.tech/docs/generators/jaxrs-jersey/). This is also true with the jaxrs-resteasy generator (where, again, the docs at https://openapi-generator.tech/docs/generators/jaxrs-resteasy/ say it's an available option).

openapi-generator version

I have the same error on version openapi-generator 5.2.0

Suggest a fix

A quick fix is to have a custom pom.mustache template from there with this block :

{{#parentOverridden}}
    <parent>
        <groupId>{{parentGroupId}}</groupId>
        <artifactId>{{parentArtifactId}}</artifactId>
        <version>{{parentVersion}}</version>
    </parent>
{{/parentOverridden}}
