PR checklist

  • Read the contribution guidelines.
  • Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh and ./bin/security/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\.
  • Filed the PR against the correct branch: master, 4.0.x. Default: master.
  • Copied the technical committee to review the pull request if your PR is targeting a particular programming language.

Description of the PR

The gradle plugin sets all System properties before generation, then
reverts them back to their original state.

System.getProperty/setProperty return null if the property was not
previously set. The Kotlin map was defined with non-nullable key/value
constraints, so setting something not commonly set (modelDocs: "false")
would result in an runtime exception.

This changes the map to support nullable values, and rather than setting
a null System property at the end, it clears those which previously had
no value.

See #551

I've added modelDocs: "false" as one of the sample's properties.

Compile and install the project and the gradle plugin, then build the sample with:

gradle -PopenApiGeneratorVersion=3.2.1-SNAPSHOT openApiGenerate --info
