No, there are no Maven archetypes for a Perspective component. We use Gradle internally, and no one (to my knowledge) has yet figured out how to build a Perspective component with Maven.

There are two public examples of a Perspective component built using Gradle:

> **[ignition-sdk-examples/perspective-component at master ·...](https://github.com/inductiveautomation/ignition-sdk-examples/tree/master/perspective-component)**
>
> master/perspective-component

> <https://github.com/inductiveautomation/ignition-sdk-examples/pull/92>
>
> This adds another perspective module component example, in the most simplified f…orm possible. There is no front-end tooling, and only the minimal required APIs for registering a component are demonstrated.  
> 
> This example is not 'production grade', as it is intended to be useful as a learning tool rather than the basis of a new module.
> 
> Fixes #81
