Description

Facing this class not found exception:

Exception in thread "main" java.lang.NoClassDefFoundError: io/ktor/client/plugins/contentnegotiation/ContentNegotiation

when I use both kotlin serialization (which uses server side ContentNegotiation) and OpenAI client whose HTTP client uses client side ContentNegotiation. I think that is what is causing this error.

    implementation("io.ktor:ktor-server-core:$kotlin_version")
    implementation("io.ktor:ktor-server-netty:$kotlin_version")
    implementation("io.ktor:ktor-server-host-common:$kotlin_version")
    implementation("ch.qos.logback:logback-classic:$logback_version")
    implementation("io.ktor:ktor-server-config-yaml")

    implementation("io.ktor:ktor-client-core:$ktor_version")
    implementation("io.ktor:ktor-client-content-negotiation:$ktor_version")
    implementation("io.ktor:ktor-client-serialization:$ktor_version") // For serialization support

    // kotlin serialization
    implementation("io.ktor:ktor-serialization:$ktor_version")
    implementation("io.ktor:ktor-serialization-kotlinx-json:$ktor_version")
    implementation("io.ktor:ktor-server-content-negotiation:$ktor_version")

    // CORS, server call logging, koin, MongoDB, firebase .. removed for clarity

    // Open AI
    implementation("com.aallam.openai:openai-client:3.8.2")

There was another issue reported and closed, however, resolution pointed to Ktor 3+ which I am already on. Any idea what may I be missing?

Environment

• openai-kotlin version: 3.8.2
• Kotlin version: 2.0.21
• OS: MacOS
• Ktor version: 3.0.0 / 3.0.3

The solution is to use beta version - 4.0.0-beta01
