title: What ":" means in the tree view of android project dependencies?
body: <p>When I view the tree view of my android project's dependencies, I see the following entry:</p>
  <pre><code>+--- androidx.legacy:legacy-support-v4:1.0.0
  |    +--- androidx.core:core:1.0.0 -&gt; 1.7.0-alpha01
  |    |    +--- androidx.annotation:annotation:1.2.0
  </code></pre>
  <p>If I understand correctly, this means that &quot;androidx.legacy:legacy-support&quot; contains a dependency on &quot;androidx.core:core&quot;, and so on</p>
  <p>There are also other entries in this tree like</p>
  <pre><code>+--- org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.70 -&gt; 1.4.30 (*)
  +--- :mopub-chartboost-adapters-8.2.0.3
  </code></pre>
  <p>Please advice what does &quot;:&quot; symbol before &quot;mopub-chartboost-adapters&quot; mean? Does &quot;org.jetbrains.kotlin:kotlin-stdlib&quot; contains dependency on &quot;mopub-chartboost-adapters&quot;?</p>
  <p>Thanks</p>
