Description

Currently the enumeration definition below generates a class with no members. The attached file archive.zip contains a complete definition (with several enumerations) that demonstrate this problem.

Command line used for generation

java -jar /home/brian/code/git/openapi-generator/modules/openapi-generator-cli/target/openapi-generator-cli.jar generate -i updated/TS29122_MonitoringEvent.yaml -g cpp-pistache-server --config config -o ./code/MonitoringEvent/server/cpp-pistache-server

Steps to reproduce

1. Create a blank working directory
2. Unzip Archive.zip to the newly created directory.
3. Generate the source using the provided command making path adjustments for your system.
4. The class SupportedGADShapes in ./code/MonitoringEvent/server/cpp-pistache-server/model/SupportedGADShapes.h has no members.

The attached file SupportedGADShapes.zip contains the .h and .cpp definitions for the enumeration.
Note that an enumeration named "INVALID" has been added in the header and is used when no default is specified.

Generator still generates enums the same way (a class with no members). Is there any chance that this issue will ever be fixed ?

Hi,
Thanks for the PR.

What is it that needed to fix and reopen and merge this PR? I will help if need.

Thanks a lot.
