Replace deprecated import for kotlin Parcelize annotation

[ghost]

This replaces the import kotlinx.android.parcel.parcelize with kotlinx.parcel.Parcelize, as the former is deprecated as of kotlin 1.4.20 (and will be removed with the next version or something)
Also see https://youtrack.jetbrains.com/issue/KT-40030.

This would also resolve issue #8073.

I'm also required to mention the technical committee for kotlin:
@jimschubert (2017/09) ❤️, @dr4ke616 (2018/08) @karismann (2019/03) @Zomzog (2019/04) @andrewemery (2019/10) @4brunu (2019/11) @yutaka0m

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.
• Run the following to build the project and update samples:

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

  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*.
  For Windows users, please run the script in Git BASH.
• File the PR against the correct branch: master, 5.1.x, 6.0.x
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

Hey @kalinjul thanks for your contribution 👍

Could you please also apply the new Parcelize plugin in the gradle file modules/openapi-generator/src/main/resources/kotlin-client/build.gradle.mustache and update the kotlin version to 1.4.20, since this was the version that this change was applied?

{{#parcelizeModels}}
apply plugin: 'kotlin-parcelize'
{{/parcelizeModels}}

And also run this commands please.

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

Thanks 😊

I added the plugin (although the android-kotlin-extensions, which was required before, wasn't included before) and generated the samples.

[4brunu]

Yes, you are right, it was probably forgotten.
Thanks for the changes, it looks good to me.
Let's wait for CI to finish.

[ghost]

I'm sorry I couldn't find the code that uses gradle 5.1.1 for building the samples. Obviously, this has to be replaced by a newer version, too.

[4brunu]

CI failed, I think it's not related to this PR.
@wing328 for me this PR is ready to merge.

[wing328]

Restarted the failed jobs. Let's see how that goes.

I don't know about the current travis failure, but shippable reports:

FAILURE: Build failed with an exception.

• Where:
  Build file '/root/src/github.com/OpenAPITools/openapi-generator/samples/client/petstore/kotlin-retrofit2/build.gradle' line: 21

• What went wrong:
  A problem occurred evaluating root project 'kotlin-petstore-retrofit2'.

Failed to apply plugin [id 'kotlin']
The current Gradle version 5.2.1 is not compatible with the Kotlin Gradle plugin. Please use Gradle 5.3 or newer, or the previous version of the Kotlin plugin.

As I had to update the kotlin gradle plugin, this error was introduced by the changes in this PR. I just don't know how to fix it, because I can't find a reference to gradle 5.2.1 anywhere in the source. It obviously has to be updated to a newer gradle version as well.

[4brunu]

I also can't find the problem 🙁
Maybe @wing328 or @jimschubert can help with this.

[wing328]

From Shippable log:

Looks like we need to install a newer version of Gradle (e.g. 5.3 or newer) to fix the build failure?

[wing328]

TravisCI failure already fixed in the master.

[4brunu]

@kalinjul I have been fighting the CI, and to make it pass, can you please revert the kotlin and gradle versions? Thanks

[wing328]

CircleCI failure already fixed in the master.

[welsinga]

It this change reverted @wing328? Because when i apply parcelizeModels: "true" kotlin-parcelize plugin isn't being used

[wing328]

Can you try the latest stable release v5.1.0 or latest master and create a new issue for tracking if it's still the case?

[welsinga]

Yes it works with 5.1.0.
