Cannot resolve Jedis client classes with Grails 4

[andersaaberg]

Lets say that I have this simple controller in Grails 3:

import grails.plugins.redis.RedisService
import redis.clients.jedis.Jedis

class HelloController {

    RedisService redisService

    def index() {
        redisService.withRedis { Jedis redis ->
            redis.ping()
        }
    }
}

this works in Grails 3.3.10 but not in Grails 4.0.0 where "./gradlew bootRun" fails with this compilation error: "unable to resolve class redis.clients.jedis.Jedis".
This is a bit odd, as redis.clients:jedis should be available in Grails 4.0.0 according to ./gradlew dependencies.

This has forced me to use "micronaut-redis-lettuce" instead of this grails-plugin with Grails 4.0.0.

This is probably due to that transitive dependencies are no longer resolved for plugins: http://docs.grails.org/latest/guide/upgrading.html#_upgrading_to_gradle_5
https://docs.gradle.org/current/userguide/upgrading_version_4.html#rel5.0:pom_compile_runtime_separation

As per @andersaaberg answer, we need to add explicit dependency in build.gradle:

...
implementation 'redis.clients:jedis:2.9.0'
...

2.9.0 version took from the redis:2.0.5 sources

Could you please verify if this is still an issue with current active version?

@puneetbehl Using grails 6.1.0 and adding the dependencies

implementation 'org.grails.plugins:grails-redis:3.0.0'
implementation 'redis.clients:jedis:2.9.0'

a project with a basic controller like the one mentioned in the original comment will compile as expected.

@andersaaberg Please upgrade to the most recent version of the Grails framework and this plugin.
