PR checklist

• Read the contribution guidelines.
• 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.
• If contributing template-only or documentation-only changes which will change sample output, build the project beforehand.
• Run the shell script ./bin/generate-samples.shto update all Petstore samples related to your fix. 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*. For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master
• Copy the technical committee to review the pull request if your PR is targeting a particular programming language.

Hum, is this related to my change ?

download failed: org.scala-sbt#compiler-ivy-integration;0.13.16!compiler-ivy-integration.jar Error during sbt execution: Error retrieving required libraries (see /home/circleci/.sbt/boot/update.log for complete log) Error: Could not retrieve sbt 0.13.16 [ERROR] Command execution failed.

Could this change have a flag to enable or disable this behaviour?

[loicsiret]

I think it shouldn't, unless you have a specific use case ?
Other languages (at my knowledge) didn't require to specify explicitly the polymorphic support. As a user, I expect the generator to be able to deserialise polymorphic list out of the box. The only thing may be to remove Gsonfire if no polymorphic support is needed.

[4brunu]

Remove Gsonfire if no polymorphic support is needed does what I need, looks a good solution to me 👍

@loicsiret I was going through the old PRs and saw this one.
Are you still interested in this functionality?

[loicsiret]

pHi Bruno, To be honest, I think it's a very important functionality for developers using GSON. However since I created this PR, I moved to Moshi, creating mustache files for the same functionality, and right now I working on KMP with Kotlin serialization 😅 Best regards Le mer. 26 mai 2021 à 05:41, Bruno Coelho ***@***.***> a écrit :
