Could not find io.confluent:kafka-protobuf-serializer:6.0.0 - maven

Question

The straight question is: why is Gradle not resolving this dependency I added
dependencies {
//kafka-protobuf-serializer
implementation("io.confluent:kafka-protobuf-serializer:6.0.0")
}
?
Accoring to mvn this is how I add such dependency in my build.gradle
compile group: 'io.confluent', name: 'kafka-protobuf-serializer', version: '6.0.0'
All my other dependencies are added with "implementation ...". So far so good. But for this speficic I got
Execution failed for task ':extractIncludeProto'.
> Could not resolve all files for configuration ':compileProtoPath'.
> Could not find io.confluent:kafka-protobuf-serializer:6.0.0.
Searched in the following locations:
- file:/C:/Users/Cast/.m2/repository/io/confluent/kafka-protobuf-serializer/6.0.0/kafka-protobuf-serializer-6.0.0.pom
- https://jcenter.bintray.com/io/confluent/kafka-protobuf-serializer/6.0.0/kafka-protobuf-serializer-6.0.0.pom
Required by:
project :
Possible solution:
- Declare repository providing the artifact, see the documentation at https://docs.gradle.org/current/userguide/declaring_repositories.html
What I am missing or messing here?

When using mvnrepository.com, take note of which repository the module is available in as you only have JCenter configured for your build (which is usually fine, just not in this case). Here the dependency is in the Confluent repository:
So you will need to add this repository to your build:
repositories {
mavenLocal()
jcenter()
maven { url "https://packages.confluent.io/maven/" }
}
