PR checklist

• [ X] Read the contribution guidelines.
• [ X] Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• [ X] Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh ./bin/configs/*.yaml
  ./bin/utils/export_docs_generators.sh
  

  (For Windows users, please run the script in Git BASH)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.1.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

@wing328 I think everything should be updated now.

Thanks @mfriesen

Can we wrap these changes inside the following mustache tags?

{{#withAWSV4Signature}}
...
{{/withAWSV4Signature}}

so that these code will only be included if the AWS auth option is enabled

e.g.

openapi-generator/modules/openapi-generator/src/main/resources/Java/libraries/okhttp-gson/ApiClient.mustache

Line 69 in 6dfaca9

{{#withAWSV4Signature}}

Sorry I'm not following.

I did wrap my new method
setAWS4Configuration(String accessKey, String secretKey, String sessionToken, String region, String service) with
{{#withAWSV4Signature}} {{/withAWSV4Signature}} just like the
public void setAWS4Configuration(String accessKey, String secretKey, String region, String service) method.

[wing328]

you're right, you did wrap it inside the function call.

i was expecting the whole method is wrapped inside the withAWSV4Signature mustache tag but the function above is not doing that either.

my intention is to completely skip the function when withAWSV4Signature is not enabled. (a user using the SDK maybe puzzle on why such AWS-related auth method exists given that the client has nothing to do with SDK)

we may address that in the upcoming v8.0.0 release as it's a potential breaking change.

thanks for the PR, which has been merged
