title: Android Studio keeps refusing to resolve com.android.support:appcompat-v7:29.0.1
body: <p>I have already referred to <a href="http://ttps://stackoverflow.com/questions/52997370/" rel="noreferrer">this</a> thread but it does not resolve my issue.</p>
  
  <p>I keep getting the error:
  <code>ERROR: Failed to resolve: com.android.support:appcompat-v7:29.0.1</code>
  in Android Studio every time I try to refresh Gradle.</p>
  
  <p>Here is my <code>build.gradle</code></p>
  
  <pre><code>apply plugin: 'com.android.application'
  
  android {
      compileSdkVersion 29
      buildToolsVersion "29.0.1"
      defaultConfig {
          applicationId "com.application.app"
          minSdkVersion 14
          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-v7:29.0.1'
      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'
  }
  </code></pre>
  
  <p>How can I fix it and also is there a website where all the version of all the android modules are listed? I could not find any myself.</p>
  
  <p>Thanks.</p>
