Hi all 👋
A real noob question...
I'm trying to run now the fat jar of my app from the command line after running ./gradlew build and I'm getting the following error:

Exception in thread "main" java.lang.IllegalArgumentException: Neither port nor sslPort specified. Use command line options -port/-sslPort or configure connectors in application.conf
        at io.ktor.server.engine.CommandLineKt$buildCommandLineEnvironment$environment$1.invoke(CommandLine.kt:78)
        at io.ktor.server.engine.CommandLineKt$buildCommandLineEnvironment$environment$1.invoke(CommandLine.kt:39)
        at io.ktor.server.engine.ApplicationEngineEnvironmentBuilder.build(ApplicationEngineEnvironmentJvm.kt:74)

        at io.ktor.server.engine.CommandLineKt.commandLineEnvironment(CommandLine.kt:98)
        at io.ktor.server.netty.EngineMain.main(EngineMain.kt:20)

I've seen that many people complain about this online but couldn't find any solution.
My application.conf is located under the resources dir as it was configured automatically by the ktor wiz 🙈

To run the app I'm execution simply java -jar ./build/libs/myapp-all.jar

All source code is available here.

Thanks in advance! 🙏

How does your conf file look like?

ktor {
  application {
    modules = [ "com.xkcddatahub.fetcher.bootstrap.ApplicationKt.module" ]
  }
  deployment {
    port = 8090
  }
  database {
    url = "jdbc:<postgresql://localhost:5432/xkcd_data_hub>"
    driver = "org.postgresql.Driver"
    user = "postgres"
    password = "secret"
  }
}

To make it work, remove the ktor_server_config_yaml dependency. This dependency forces Ktor to load the application.yaml configuration file instead of application.conf .

Thanks @Aleksei Tirman [JB]! I've added this at the beginning as I didn't know ktor comes with a .conf setup and forgot about it 🤦‍♂️
