Hello every one, I am failing to configure ktor embeddedServer(CIO) to auto reload. I believed I have followed the documentation and have everything in place, but still auto reload wont work

• build.gradle.kts contains "-Dio.ktor.development=true"
• my main function contains embeddedServer(...,watchPaths=listOf("classes"))
I am running ./gradlew :build -t (also tried with jar and assemble) in one terminal and running ./gradlew :run in another. I make changes and save the main file (the rebuild happens in the build terminal)

I go to the browser and refresh the page but changes are not reflected.

I am on kotlin 2.0.0, Java 18.0.2.1, tried ktor (2.3.9,2.3.12 and 3.0.0-beta-2) to no avail. What else am I missing here??

Do you see logs saying that the auto-reloading is watching for package changes? For example:

LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/gpt for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/META-INF for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/algo for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/exposed for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/packageB for changes.
LOG [] DEBUG ktor.application Watching /home/stexe/projects/ktor_sandbox/build/classes/kotlin/main/packageA for changes.

No, I do not see these logs at all

[Aleksei Tirman [JB]]

Then either the logger doesn't log on the DEBUG level or the development mode is off.

[andylamax]

I have checked that development mode is set

calling System.getProperty("io.ktor.development") returns true.

What more do I need to do to enable logging?

[Aleksei Tirman [JB]]

You can find the information about the logging configuration in the documentation.

Same issue with kotlin 2.0.21, works fine on 1.9.xx.
