title: Gradle sync in Android Studio showed an error 'Could not GET kotlin-stdlib-jdk8-1.3.50.pom'. with status code 403 from server
body: <p>I created a new Android project by importing one of our company projects today. I am not an Android programmer but I had to run it and measure performance. So I installed Android Studio today on my Ubuntu 18.04 box. I also update plugins.</p>
  <p>During the first Gradle sync, there was an error:</p>
  <pre><code>Could not GET 'http://jcenter.bintray.com/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.3.50/kotlin-stdlib-jdk8-1.3.50.pom'. Received status code 403 from server: Forbidden
  </code></pre>
  <p>The build.gradle file looks like the following:</p>
  <pre><code>buildscript {
      repositories {
          jcenter { url &quot;http://jcenter.bintray.com&quot; }
          google()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.5.2'
      }
  }
  
  allprojects {
      repositories {
          jcenter { url &quot;http://jcenter.bintray.com&quot; }
          google()
      }
  }
  </code></pre>
  <p>With my Chrome,
  I cannot access 'http://jcenter.bintray.com/org/jetbrains/kotlin/kotlin-stdlib-jdk8/1.3.50/kotlin-stdlib-jdk8-1.3.50.pom'
  but I can download pom file with <code>https</code> with by browser.</p>
  <p>So I tried to change <code>http</code> to <code>https</code> in the above <code>build.gradle</code> but got the following errors:</p>
  <pre><code>Repository not found.
  Process command 'git' finished with non-zero exit value 1
  </code></pre>
  <p>I searched and tried the following:</p>
  <pre><code>buildscript {
      repositories {
          google()
          jcenter()
      }
      dependencies {
          classpath 'com.android.tools.build:gradle:3.5.2'
      }
  }
  
  allprojects {
      repositories {
          google()
          jcenter()
      }
  }
  </code></pre>
  <p>I also tried to add some url in <code>maven{ url ... }</code> but got the same error (<code>Repository not found.</code>)</p>
  <p>Please help me how to successfully finish gradle sync.</p>
  <p>Thank you!</p>
