Could not find method jackOptions() for arguments, why?

Question

when I added

jackOptions {
        enabled true
    }

I face the error
Could not find method jackOptions() for arguments [build_eu0icfxibozhk3nsdn05m3i57$_run_closure1$_closure3$_closure6@4c9324a1] on DefaultConfig_Decorated{name=main, dimension=null, minSdkVersion=DefaultApiVersion{mApiLevel=14, mCodename='null'}, targetSdkVersion=DefaultApiVersion{mApiLevel=30, mCodename='null'}, renderscriptTargetApi=null, renderscriptSupportModeEnabled=null, renderscriptSupportModeBlasEnabled=null, renderscriptNdkModeEnabled=null, versionCode=1, versionName=1.0, applicationId=com.example.myapplication, testApplicationId=null, testInstrumentationRunner=androidx.test.runner.AndroidJUnitRunner, testInstrumentationRunnerArguments={}, testHandleProfiling=null, testFunctionalTest=null, signingConfig=null, resConfig=null, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}, mWearAppUnbundled=null} of type com.android.build.gradle.internal.dsl.DefaultConfig.

how can I solve it ??

this is the app's build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.0"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 14
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        jackOptions {
            enabled true
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: "libs", include: ["*.jar"])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

}

The old Jack compiler has been gone for a couple of years now. Do not add jackOptions to a modern project's Gradle scripts.
