Description

Regression between 7.17.1 and 7.18.0 (versions here are the Gradle plugin, I'm not sure what the underlying lib versions are) . Generated clients with kotlin generator and jvm-spring-restclient library now erroneously ignore the basePath values from the Spring RestClient.

Previously if you set a base path as myService/ and host as www.bob.org. A generated API call against POST action would look like:

POST www.bob.org/myService/action

In 7.18.0 the base path is ignored and you get:

POST www.bob.org/action

Rolling back to 7.17.1 fixes the issue.
