error: object Service is not a member of package com.twitter.finagle - Defining Bazel dependencies in Build file, Scala finagle - scala

Question

Im trying to add the finagle-http library to my new bazel project as an external maven dependency. But getting the following error. I assume im doing something wrong in creating the build without fully understanding it. Trying to learning. Appreciate any help on this.
error: object Service is not a member of package com.twitter.finagle
error: object util is not a member of package com.twitter
error: type Request is not a member of package com.twitter.finagle.http
error: object Response is not a member of package com.twitter.finagle.http
error: Symbol 'type com.twitter.finagle.Client' is missing from the classpath. This symbol is required by 'object com.twitter.finagle.Http'.
error: not found: value Await
The same code is working using sbt. Below is the code.
import com.twitter.finagle.{Http, Service}
import com.twitter.finagle.http
import com.twitter.util.{Await, Future}
object HelloWorld extends App {
val service = new Service[http.Request, http.Response] {
def apply(req: http.Request): Future[http.Response] =
Future.value(http.Response(req.version, http.Status.Ok))
}
val server = Http.serve(":8080", service)
Await.ready(server)
}

Working SBT dependency that was working in my initial sbt project
libraryDependencies += "com.twitter" %% "finagle-http" % "21.8.0"

Answer 1

Figured out the issue, unlike in sbt, in bazel i had induvidualy add the related dependencies. I modified the workspace as below.
maven_install(
artifacts = [
"com.twitter:finagle-http_2.12:21.8.0",
"com.twitter:util-core_2.12:21.8.0",
"com.twitter:finagle-core_2.12:21.8.0",
"com.twitter:finagle-base-http_2.12:21.8.0",
"com.fasterxml.jackson.module:jackson-module-scala_2.12:2.11.2",
"com.fasterxml.jackson.core:jackson-databind:2.11.2",
],
repositories = [
"https://repo.maven.apache.org/maven2/",
