Build error upgrading to 2.x

[rudas23]

I'm getting build errors when upgrading to 2.x

Basically the project structure is:
App -> Feature A -> ApolloGraphQL

Project build.gradle

plugins {
    id("com.apollographql.apollo").version("2.5.2").apply(false)
}

ApolloGraphQL/build.gradle

apply plugin: 'com.apollographql.apollo'

apollo {
    generateKotlinModels = true

    service("product") {
        sourceFolder.set("com/example/app/product")
        rootPackageName.set("com.example.app.product")
    }
    ... 
    ...
}

dependencies {
    implementation "com.apollographql.apollo:apollo-runtime:2.5.2"
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.4.21"
}

Build error when building module

Have tested upgrading okio lib without success as well...
Have also checked responses in here and here

Hi 👋 , yep, that looks like this okio decodeHex extension method that is only in recent versions. Do you use buildSrc ? If yes, could share the contents of buildSrc/build.gradle[.kts]?

    id 'org.jetbrains.kotlin.jvm' version '1.3.41'

    maven {
        url "${mavenUrl}"
        credentials {
            username "${mavenUsername}"
            password "${mavenToken}"
        }
    }

}
compileKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
compileTestKotlin {
    kotlinOptions {
        jvmTarget = "1.8"
    }
}
apply from: rootProject.file('../gradle/ktlint.gradle')

[martinbonnin]

Can you add okio there ?

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    ...
    implementation 'com.squareup.okio:okio:2.9.0'
}

Changing okhttp version in buildSrc seems solved the problem. Thanks!
