Hi, I'm trying to make a basic usage of Koog but falling at the first hurdle when constructing a client. Details in thread 👉 🧵

[darkmoon_uk]

Get this error as if the constructor isn't on the class-path:

Exception in thread "main" java.lang.NoSuchMethodError: 'void ai.koog.prompt.executor.clients.openai.OpenAILLMClient.<init>(java.lang.String, ai.koog.prompt.executor.clients.openai.OpenAIClientSettings, io.ktor.client.HttpClient, kotlin.time.Clock, int, kotlin.jvm.internal.DefaultConstructorMarker)'

...and the line it fails on is simply:

val executor: PromptExecutor = SingleLLMPromptExecutor(OpenAILLMClient(apiKey, openaiConfig))

I've got ai.koog:koog-agents:0.3.0 in my implementation.
Looks like version skew but I don't have any other transitive Koog dependencies.

[darkmoon_uk]

Are there any known packaging issues?

[Didier Villevalois]

I use the 0.3..0 version in my app (though not the OpenAI client), so I don't think there is a problem with its packaging... Is the line you quoted in your code or in Koog's codebase? Also, can you check Gradle dependencies for Koog's transitive dependencies?

Are there any known packaging issues?

Hello! As of yet, we are not aware of packaging issues of this kind. Could you provide a little bit more info on how you reference the package?

[darkmoon_uk]

I figured out the problem, a victim of the kotlinx.datetime 0.7.1 migration 😕

[darkmoon_uk]

The Clock type mis-matching I suppose.

[darkmoon_uk]

Discovered by going through the whole process of spinning up Koog in a new JVM App, then iterating it towards the bad config - it worked until I added the explicit kotlinx.datetime 0.7.1 dependency.

[Didier Villevalois]

Yeah you must use the 0.7.1-0.6.x-compat version for now.
