openapi-processor samples
This project contains a number of sample projects of openapi-processor that show different configurations of openapi-processor. The samples don’t do anything useful.
A few of the examples have a pom with the maven plugin, most of the examples use gradle (a few have a groovy dsl build.grade, most have a kotlin dsl build.gradle.kts).
The name of the example project gives a hint which feature (configuration) and framework are showcased in the example. Most simply use java, the newer examples usually use kotlin.
