Ktor dependency - maven

Question

For context, I am new to Kotlin and Ktor.
This is Application.kt file. The problem is with install, Locations, Authentication, ContentNegotiation. I'm unable to import them even though I have added their maven dependency.
The pom.xml file is added below.
import com.userTodo.auth.JwtService
import com.userTodo.auth.MySession
import com.userTodo.auth.hash
import com.userTodo.repository.DatabaseFactory
import com.userTodo.repository.TodoRepository
import com.userTodo.repository.UserRepository
import com.userTodo.routes.todos
import com.userTodo.routes.users
import io.ktor.http.*
import io.ktor.server.application.*
import io.ktor.server.response.*
import io.ktor.server.request.*
import io.ktor.server.routing.*
import io.ktor.server.auth.*
import io.ktor.server.auth.jwt.*
fun main(args: Array<String>): Unit = io.ktor.server.netty.EngineMain.main(args)
fun Application.module() {
install(Locations) {
}
DatabaseFactory.init()
val userDb = UserRepository()
val todoDb = TodoRepository()
val jwt = JwtService()
val hashFunction = {s:String -> hash(s)}
install(Sessions) {
cookie<MySession>("MY_SESSION") {
cookie.extensions["SameSite"] = "lax"
}
}
install(Authentication) {
jwt("jwt") {
}
}
install(ContentNegotiation) {
json()
}
routing {
users(userDb,todoDb,jwt,hashFunction)
todos(todoDb,userDb)
}
}

I have been working to fix this for the last few hours, searching the web exhaustively, and this is my last resort.

Answer 1

The dependency ktor-server-content-negotiation-jvm for the ContentNegotiation plugin is missing in the pom.xml file. The artifact name for the Locations plugin must have a platform suffix, e.g. ktor-server-locations-jvm. The Authentication plugin can be imported just fine using your pom.xml file.
