title: The component is declared by more than one NgModule
body: <p>So i created a component <strong>ExampleComponent</strong> and declared it in a module that <strong>isnt</strong> listed in app.module.
  Next i want to declare the component <strong>ExampleComponent</strong> in a module that <strong>is</strong> listed in app.module. How do i do this? If i simply declare it, than i get the following error: the component <strong>ExampleComponent</strong> is declared by more than one NgModule.</p>
  <p>abc.module.ts</p>
  <pre><code>import { ExampleComponent} from '../Example/Example.component';
  @NgModule({
    declarations: [
      ExampleComponent
    ]
  })
  </code></pre>
  <p>app.module.ts</p>
  <pre><code>import { NewModule} from '../new/new.component';
  @NgModule({
    imports: [
      NewModule
    declarations: [
      
    ]
  })
  </code></pre>
  <p>new.module</p>
  <pre><code>import { ExampleComponent} from '../Example/Example.component';
      @NgModule({
        declarations: [
          ExampleComponent
        ]
      })
  </code></pre>
