Android Studio keeps refusing to resolve com.android.support:appcompat-v7:29.0.1 4 answers

I want to try Intellij Platform for android development but even after fresh it shows gradle failures. Please help.

I have tried tweaking the line

implementation \'com.android.support:appcompat-v7:29.+\'

to some other versions but to no avail.

Here is my module level gradle

    apply plugin: \'com.android.application\'

android {
    compileSdkVersion 29
    buildToolsVersion \"29.0.1\"
    defaultConfig {
        applicationId \"com.example.myapplication\"
        minSdkVersion 23
        targetSdkVersion 29
        versionCode 1
        versionName \"1.0\"
        testInstrumentationRunner \"android.support.test.runner.AndroidJUnitRunner\"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(\'proguard-android-optimize.txt\'), \'proguard-rules.pro\'
        }
    }
}

dependencies {
    implementation fileTree(dir: \'libs\', include: [\'*.jar\'])
    implementation \'com.android.support:appcompat-v7:29.+\'
    implementation \'com.android.support.constraint:constraint-layout:1.1.3\'
    testImplementation \'junit:junit:4.12\'
    androidTestImplementation \'com.android.support.test:runner:1.0.2\'
    androidTestImplementation \'com.android.support.test.espresso:espresso-core:3.0.2\'
}

Here is my project level Gradle

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

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath \'com.android.tools.build:gradle:3.1.0\'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

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

The errors which I am getting while Intellij builds the gradles are
