Cannot get property 'compileSdkVersion' on extra properties extension as it does not exist Open File

I imported a project downloaded from GitHub into my Android Studio project as module. The "Import module..." wizard worked fine, but when the Adroid Studio tried to rebuild the project, it returned me this error:

Cannot get property 'compileSdkVersion' on extra properties extension as it does not exist Open File

The error is related to this line in the "build.gradle" file of the imported module:

compileSdkVersion rootProject.compileSdkVersion

I tried to add "ext" section in the project "build.gradle" like this:

ext {
    compileSdkVersion 26
}

But in this way I receive a new error:

Gradle DSL method not found: 'compileSdkVersion()' Possible causes: ...

Another way:

Your build.gradle in top-level module

ext {
    minSdk = 21
    targetSdk = 29
    compileSdk = 29
    buildTools = '29.0.3'
}

Your build.gradle in app module

android {
    def buildConfig = rootProject.extensions.getByName("ext")

    compileSdkVersion buildConfig.compileSdk
    buildToolsVersion buildConfig.buildTools
    defaultConfig {
        minSdkVersion buildConfig.minSdk
        targetSdkVersion buildConfig.targetSdk
    }
    // ...
}

In your top-level file use:

ext {
    compileSdkVersion = 26
}

In your module/build.gradle file use:

android {
  compileSdkVersion rootProject.ext.compileSdkVersion
  ...
}

Change your .gradle android part to this

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "your App id"
        minSdkVersion 18
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

In build.gradle you need to write compilesdkversion under android tag as in this example:

android { .. compileSdkVersion 26 // 26 is an example ..}

By the way. You can build that module as library then import it into your project as .aar file.
