Eclipse users and contributors and the Eclipse Foundation are working together to create an eco-system for Long-Term Support of the Eclipse code.
Within this eco-system, you will find many companies or individuals that will service you. Access to the right organization is available in the LTS Marketplace.
The advantage over doing it yourself or working outside of the LTS eco-system is that your service provider (who should be a member of the LTS Working Group) is a subject matter expert and has access to existing issues. He will provide you with reliable new builds, aggregated and tested in the shared Eclipse Long-Term Support infrastructure.
