I've just uploaded to the dev update site a new release which includes support for Web Tools Project.
It's been tested against the wicket archetype and provides:
- Integration with the new project and project import wizards.
- If you're packaging is war, the project should automatically be WTP enabled.
- Filtering of deployed artifacts
- Only artifacts with default scope or compile scope will be deployed to your testing server.
Usual WTP features like hot deployment of modified java files and resources, debugging and so on are also working.
