Error: "Unresolved reference: versionCode" in build.gradle.kts

Question

I'm trying to add a new module (library module) to my project but in build.gradle.kts (for library module) I have this error:

org.gradle.internal.exceptions.LocationAwareException: Build file ' ... /build.gradle.kts' line: 13
Script compilation errors:

  Line 13:         versionCode = 1
                   ^ Unresolved reference: versionCode

  Line 14:         versionName = "1.0"
                   ^ Unresolved reference: versionName

.
.
.

Caused by: ScriptCompilationException( ... )

build.gradle.kts

plugins {
    id("com.android.library")
    id("kotlin-android")
}

android {
    compileSdk = 30
    buildToolsVersion = "30.0.3"

    defaultConfig {
        minSdk = 21
        targetSdk = 30
        versionCode = 1       //error: Unresolved reference
        versionName = "1.0"   //error: Unresolved reference

        testInstrumentationRunner = "androidx.test.runner.AndroidJUnitRunner"
        consumerProguardFiles("consumer-rules.pro")
    }

    buildTypes {
        release {
            isMinifyEnabled = false
            proguardFiles(
                getDefaultProguardFile("proguard-android-optimize.txt"),
                "proguard-rules.pro"
            )
        }
    }
    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }
    kotlinOptions {
        jvmTarget = "1.8"
    }
}

I would be grateful for any help

versionCode and versionName are meaningless in a library module. Use them only in the application module.

In the long term, Google plans to remove them from the DSL altogether in some version of Android Gradle Plugin:

In a future version of Android Gradle plugin, the versionName and versionCode properties will also be removed from the DSL for libraries.

(source)

If you are on an early non-stable version of AGP, you might have this change already. The code templates in Android Studio are not always in sync with the tooling changes.

Thanks for the answer but this code is auto-generated by android studio and all library `build.gradle` files have the `versionCode` and `versionName` otherwise we can't set version name to libraries. – Ehsan msz Jun 02 '21 at 10:59

A little late, but the version phrases are indeed useless for libraries. Only used in releases. If you do need them in code, use `BuildConfigField` – Mahdi-Malv Oct 26 '21 at 13:16
You may also have to check you didn't apply `com.android.application` instead of `com.android.library` for a library module! It happened to me. – Mohsen Mirhoseini Jun 27 '23 at 11:37

Remove versionCode and versionName from library module and check again
