Hello guys, I'm getting a really rare issue when deploying the backoffice.

I only can deploy the module with the "run" task:

- I've tried to configure a build configuration like this (Netty): https://ktor.io/servers/engine.html but the error is is

No configuration setting found for key 'ktor'

The application.conf is in resources directory, and "run" task configuration is based on it, so... I don't understand anything.

I've also tried to create a new project like https://ktor.io/quickstart/faq.html#cannot-find-application-conf is suggesting, but I'm getting the same issue

Also, If I try to run with "play button on main class" on IntelliJ, IntelliJ says "cannot find main class"

Have you tried to generate a project with this?
https://ktor.io/quickstart/generator.html

[Sergio Casero]

Yep

And how are you trying to deploy the module?

[Sergio Casero]

with:
gradlew backendrun works

[Sergio Casero]

But with run config nope

Oh you mean running using IntelliJ

[Sergio Casero]

Yes yes, with gradle works fine

[Sergio Casero]

(except autoreload)

Depending on the kind of project there are a few known issues. I’d suggest to execute the :run gradle task instead.
You can also redirect run and test tasks to use gradle

But with

gradlew run

autoreload doesn't work

[Sergio Casero]

By the way, the project is available on github, I'm playing with the multiplatform libs https://github.com/sergiocasero/votlin-app/tree/feature/backend_get_talks

Running mpp projects have some issues like that one I guess

[Deactivated User]

Though it should work fine for pure JVM projects

[Sergio Casero]

Ok ok, thanks 🙂

I am seeing the same issue now

[coder82]

autoreload doesn't apply the changes, when I enable the DEBUG logging, I can see a bunch of classes traced from ktor:
log.debug("Class Loader: $baseClassLoader: ${debugUrls.filter { !it.toString().startsWith(jre) }}")

[coder82]

this code is from ApplicationEngineEnvironment.kt

[coder82]

but when I refresh my webpage, changes are not reflected, it's still running on the old code

[coder82]

I am using gradle build -t

[coder82]

and

[coder82]

gradle run

[coder82]

if I go and manually delete the classes, indeed gradle triggers and rebuilds them, then ktor traces again all classes on page reload, but changes are not applied looks like

[coder82]

I am running on 1.2.61, ktor 0.9.4

[coder82]

Carlos u there?

[Deactivated User]

Yes, now I’m here. Let me read

[Deactivated User]

Which java version are you using?

[coder82]

1.8.0_172

[coder82]

yes I am aware Java 9 doesn't support autoreload, correct?

[coder82]

It's really weird because when I tried this feature months ago, it was working fine

[Deactivated User]

Right, it uses ClassLoading stuff and with newer java versions they changed how all that works to make java more aot-friendly

[Deactivated User]

let me check

[Deactivated User]

Works for me

[Deactivated User]

in one terminal ./gradlew build -t, in other ./gradlew run and then changing Hello World to something else, changes it.

I am running this sample: https://github.com/ktorio/ktor-exercises/tree/master/solutions/exercise4

[coder82]

I am using kotlin 1.2.61, might that affect something?

[coder82]

the gradle version is 4.10 over here

[Deactivated User]

Gradle 4.10.2 and java version "1.8.0_162" here.

Not sure. I’d suggest you to try the same as me (the exercise4 with your gradle and java versions) and if it works then mutate versions until it doesn’t work for you and then report. Can’t think of anything else to figure out what’s going on

[coder82]

ok I'll try this evening
