Support for Groovy 4

[Benthum]

I am trying to upgrade one of my services to use Groovy 4, and since the springdoc-openapi-groovy library is targeting the old maven location (org.codehaus.groovy vs org.apache.groovy) and v3, it is running into conflicts.

I believe it would be best to create a separate library for groovy 4 to avoid breaking anyone still on groovy 3. i.e. springdoc-openapi-groovy4

I isolated this library as the only one blocking me, but without it swagger isn't working correctly since I am using groovy.

Below is a screenshot showing the error that I get.

@Benthum,

Not reproducible even after adding groovy 4.
Isn't excluding the jar org.apache.groovy v3 enough ? if it's so, we can make this one optional for the next release.

But before, try providing a Minimal, Reproducible Example - with HelloController that reproduces the problem.

There is no need to open a new ticket. This one, can be reopened if the relevant information are provided.

Here is a repo I made to show off the example
main branch works and is groovy 3, the other branch is groovy 4 and reproduces the error I saw.

Thanks for the suggestion of excluding the jar, that does seem to fix it. Good to have a workaround in the meantime until official support can be added.

I updated my example branch with the exclusion in case anyone else runs into the same problem.

@Benthum,

A fix has been added to the latest SNAPSHOT, so that you won't need to exclude the dependency when using groovy4.
