Just get in contact with us through the discussions and share your ideas or report issues.
Please bear in mind that this is a community project and not a product you contracted support for and as a result, some contributors may or may not look at your support requests on demand and if you do not provide the fix/implementation yourself, the issue might even never get fixed.
If you require dedicated help with Tycho or want to make sure a bugfix or feature is handled with priority, the following companies offer commercial support for Tycho
Tycho is an essential part of the build and release infrastructure for many Eclipse IDE-based projects and products. Its continued development and maintenance depend on contributions from individuals, organizations, and the wider Eclipse community. If you or your organization rely on Tycho, there are several ways to help keep it maintained, reliable, and available for future releases.
Test snapshots of Tycho early and often so that regressions are found early before we start the release process. This results in faster releases and maybe even more frequent releases if we are certain that snapshots are production-ready.
Consider contributing developer time to support Tycho's ongoing maintenance and development. You can:
- Fix bugs and implement improvements.
- Improve documentation and examples.
- Review open pull requests
- Answer questions on the discussions, or
- Contribute integration tests for features and build configurations your projects depend on.
Even small contributions help reduce the maintenance burden and improve Tycho for everyone.
Maintaining Tycho and the wider Eclipse build and release infrastructure requires ongoing engineering effort. Community contributions are valuable, but without sustained funding, the long-term maintenance and delivery of these essential technologies could be at risk.
The Eclipse IDE Working Group's Development Funding Initiative pools resources from participating organizations to fund critical development, maintenance, and release engineering work. It provides a transparent, coordinated approach to investing in shared technical priorities.
If your organization relies on Tycho, supporting this initiative is a practical way to help secure its long-term sustainability.
You don't need to contribute code to help sustain Tycho and the wider Eclipse ecosystem. Financial sponsorship helps fund the engineering work required to maintain these shared technologies.
- For individuals: Support the Eclipse IDE ecosystem with a contribution starting from €5 through the Eclipse IDE sponsorship program. Every contribution helps.
- For companies: If your organization relies on Tycho and would like to make a larger annual commitment, contact the Eclipse IDE Working Group team to discuss corporate sponsorship opportunities.
You can also support developers who contribute directly to Tycho. Individual sponsorship is a separate way to recognize and fund their ongoing work:
- Christoph Läubrich - A sample of his recent work can be seen here.
Direct sponsorship supports individual maintainers, while the Eclipse IDE Working Group's Development Funding Initiative provides a coordinated approach to funding shared technical priorities.
Tycho has a very large user-base and thus we use exhaustive test-suites to ensure everything works well. This comes at a cost of also using a lot of processing power.
The following Organizations support Tycho by providing processing power for their builds:
Eclipse Foundation - host our CI Infrastructure, become a friend of Eclipse and support the Eclipse Foundation in general
Renesas Electronics Corporation - sponsors a resource pack with 2 CPU / 8 GB RAM
SAP SE - sponsors two resource packs with 2 CPU / 8 GB RAM each
Red Hat, Inc. - sponsors a resource pack with 2 CPU / 8 GB RAM
Sigasi - sponsors a resource pack with 2 CPU / 8 GB RAM
If your Organization is an Eclipse Foundation Member you can help us by allocating available resource packs to Tycho. Additional resources help reduce CI build times and improve the development and testing process.
Member Organizations can check their available resource packs through the Eclipse membership portal.
