title: In a custom gradle plugin, how to add task depends on task which is defined in other plugin?
body: <p>for example, I have a plugin:
  <strong>public class PluginA implements Plugin.</strong></p>
  
  <p>and I will create a task <em>taskA</em>. Now I want to set: <em>taskA.dependsOn taskB</em>, but taskB is defined in PluginB.</p>
  
  <p>Does it possible to do this, if can, how to do it?</p>
