cannot resolve symbol gson

I have big troubles using the gson library. When building the project i get:

"Cannot resolve symbol gson"

I have googled for hours but no solution seems to work. Here is my build.gradle file:

android {
    compileSdkVersion 24
    buildToolsVersion "28.0.2"
    defaultConfig {
        applicationId "com.example.jasminkrhan.vaktija"
        minSdkVersion 24
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {

    compile fileTree(include: ['*.jar'], dir: 'libs')
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:24.2.1'
testCompile 'junit:junit:4.12'
compile 'com.google.code.gson:gson:2.8.2'

}

And also my build.gradle file for the project:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        jcenter {
            url "http://jcenter.bintray.com/"
        }
    }

    repositories {
        maven  {
            url "http://repo1.maven.org/maven2"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {

    repositories {
        jcenter {
            url "http://jcenter.bintray.com/"
        }
    }

    repositories {
        maven  {
            url "http://repo1.maven.org/maven2"
        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

Does someone see something wrong with my code? Why does not android studio find the library? I have already tried to restart Android Studio but that doesn't help.

Try to write the repositories all in one, and use the functions included for Google dependencies and jcenter already, instead of providing the URL. Like so:

buildscript {
...
    repositories {
        google()
        jcenter()
    }
}

And also:

allprojects {
    repositories {
        google()
        jcenter()
    }
}

It's also important that you start using the implementation tag instead of compile in gradle, as its being deprecated:

implementation 'com.google.code.gson:gson:2.8.5'

compile is outdated. Please use implementation

implementation 'com.google.code.gson:gson:2.8.5'

You need these in Project Level build.gradle

buildscript {

repositories {
    google()
    jcenter()
}

.....
allprojects {
    repositories {
        google()
        jcenter()
    }
}
