Problem I’m developing an Android app that uses both Google’s Gemini API (which depends on Ktor 2.x) and Supabase SDK (which requires Ktor 3.x). When including both libraries, I encounter class resolution errors due to conflicting Ktor versions.

• Environment Android Studio Meerkat | 2024.3.1

• Kotlin 1.9.x

• Jetpack Compose

• Hilt for DI

• Target SDK 35

Error Details The app crashes with alternating errors:

Supabase-related error:

java.lang.NoClassDefFoundError: Failed resolution of: Lio/ktor/client/HttpClientJvmKt;  
at io.github.jan.supabasework.KtorSupabaseHttpClient.\<init\>(KtorSupabaseHttpClient.kt:55)

Gemini-related error:

java.lang.NoClassDefFoundError: Failed resolution of: Lio/ktor/client/plugins/HttpTimeout;
at io.ktor.client.engine.okhttp.OkHttpEngine.<init>(OkHttpEngine.kt:40)
at com.google.ai.client.generativeaimon.APIController.<init>

Dependencies (build.gradle.kts) kotlin Copy // Supabase SDK (Ktor 3.x) :

implementation(libs.supabase.auth) 
implementation(libs.supabase.postgrest) 
implementation(libs.supabase.realtime) 
implementation(libs.supabase.storage) 
implementation(libs.supabase.functions)

// Gemini API (Ktor 2.x)
implementation(libs.generativeai)

// Explicit Ktor dependencies
implementation(libs.ktor.client.android)

Attempted Solutions Excluded Ktor from Gemini in build gradle.kts

implementation(libs.generativeai) {
    exclude(group = "io.ktor")
}

Added explicit Ktor versions:

implementation("io.ktor:ktor-client-core:3.1.0")  
implementation("io.ktor:ktor-client-okhttp:3.1.0")  
// Also tried mixing versions (failed)  
implementation("io.ktor:ktor-client-plugins:2.3.7")  

Adjusted packagingOptions:

packaging {  
    resources {  
        pickFirsts.add("META-INF/INDEX.LIST")  
        pickFirsts.add("META-INF/ioty.versions.properties")  
        excludes.add("META-INF/*.kotlin_module")  
    }  
}  

None resolved the conflict.

Question How can I resolve this dependency conflict to use both Supabase (Ktor 3.x) and Gemini API (Ktor 2.x) in the same Android app? Is there a safe way to handle major version mismatches for Ktor?
