title: Add specific repository to build file
body: <p><strong>Problem:</strong> I would like to include that <a href="https://android-arsenal.com/details/1/2835" rel="nofollow noreferrer">library</a> to my project. When I add the dependency I get: </p>
  
  <blockquote>
    <p>Failed to resolve: com.github.glomadrian:loadingballs1.1</p>
  </blockquote>
  
  <p><strong>Question:</strong> How do I have to change my gradle file to solve the problem? I think it has something to do with adding the repository maven. If it is like that, where do I have to put it correctly?</p>
  
  <p><strong>Note:</strong> I have found a <a href="https://stackoverflow.com/questions/28295933/difference-between-build-gradleproject-and-build-gradlemodule">post</a> that seems to answer my question but unfotunately I still get the issue. </p>
  
  <p>The library gives a small tutorial: </p>

    <p>Add the specific repository to your build file:</p>

  <p>Their sample code: </p>
  
  <pre><code>repositories {
      maven {
          url "https://jitpack.io"

  </code></pre>
  
  <p>I have added the maven repository to my build file like that: </p>
  
  <p>build.gradle (Project)</p>
  
  <pre><code>   buildscript {
      repositories {
          jcenter()

          //Maven plugin
          classpath 'com.github.dcendents:android-maven-gradle-plugin:1.3'
  
          // NOTE: Do not place your application dependencies here; they belong
          // in the individual module build.gradle files
      }
  }
  
  allprojects {
      repositories {
          jcenter()
          maven { url "https://jitpack.io" }
      }
  
  }
  
  task clean(type: Delete) {
      delete rootProject.buildDir
