CBI

The Eclipse Common Build Infrastructure (CBI) is an initiative combining infrastructure, services, technologies and best practices for building, testing and delivering software at the Eclipse Foundation.

Goals

Primary goals of the CBI initiative are:

  • Make it easy for anyone to contribute to Eclipse projects.
  • Make it easy for projects to follow open governance and transparency best practices.
  • Provide a set of industry-grade services (or integration with some widely adopted 3rd party services) for building and distributing Eclipse projects.

Asking for Help

Service Level Agreement (SLA)

Most CBI services are Tier 2 - Best Effort, which means they are expected to be available at all times, and rapid restoration can be expected in the event of an outage. Eclipse Strategic Members can contact Webmaster in certain cases of off-hours support.

Please see IT_SLA for more information on the Eclipse Foundation IT Services SLA.

Provided Services

CI Environment (Jenkins)

We provide dedicated Jenkins instances to projects. See also Jenkins.

Jenkins is a continuous integration (CI) server used on Eclipse Foundation servers for Eclipse projects as part of the Common Build Infrastructure (CBI). Jenkins instances are maintained by the Eclipse Webmasters/Release Engineers.

NOTE: JIPP instances are being migrated from a standalone implementation to a Kubernetes cluster implementation.

Requesting a JIPP instance

Please file a bug against Eclipse Foundation > Community > CI-Jenkins to request your project's own instance. Please ensure your project lead can +1 the request. Please specify if you wish to grant write access to your download area and/or code repositories.

Security issues
There may be security issues related to using the Gerrit plugin, more especially when allowing the CI system to write directly to the code repos and downloads area. If you request plugins other than those installed by default, webmasters may not be able to help troubleshoot any issues that you may encounter with your instance.


What's provided?

Each Eclipse Project has access to one Jenkins instance (JIPP), including the following:

  • (1) Jenkins instance, with (1) Resources Pack (see below)
    • Membership-sponsored projects may allocate more resources (see below)
  • Digital signing Service: Java JAR, Java Cryptography Extensions, Windows Portable Executable with Microsoft Authenticode, macOS application bundles.
  • Packaging service: Apple Disk Image (.dmg), Linux Flatpak
  • Disk space: Ephemeral for builds, permanent for release builds.
  • (1) 1vCPU/3.75G/30G Linux Virtual Server (if needed) (courtesy of Microsoft Azure). Projects sponsored by Strategic Members can engage with the Foundation to get out of spec Virtual Server.
  • Access to worldwide download mirrors

Additional Resource Packs

Each Eclipse Project has access to one Resources Pack for building. For some projects, that may not be enough. Projects sponsored by Eclipse Membership (via Project Lead) have additional Packs, based on membership level. These Packs can be allocated to projects. See the Jenkins wiki page to see how packs translate to Jenkins builds.

  • Some resources are only available to Enterprise and Strategic members.
  • Enterprise and Strategic members can engage with the Foundation to acquire additional Packs.
Resource Pack
Agent type Linux (containerized, no root)
vCPU 2 (burst to 4)
RAM 8GiB
Disk 50GB
External slave support Yes


Dedicated Agent
Agent type Linux/Windows/macOS (VMs)
vCPU 4
RAM 8GiB
Disk 100GB

Resource Packs Included in Membership

Eclipse Foundation Member Organizations have access to Resource Packs based on their membership level.

Dedicated Agents N/A N/A N/A 0 0 0 2

Assigning Resource Packs to a Project

Resource Packs are assigned by Member organizations of the Eclipse Foundation to Eclipse Projects they sponsor. Member Organizations must have a Project Lead on the Project. Packs are assigned as a whole to a single project (i.e., can’t split Packs across multiple projects). A member can assign several packs to a single project.

Note.png
Important
Before asking for packs for your project, please ensure you have the proper authorization to consume those resources on behalf of your organization. We will assume you've discussed with other project leads internally when we obtain the +1 authorization to apply the resource pack to a project.


To assign a pack to a project, please file a Bug.

CI Environment (Third-party)

If you host your Eclipse project git repository at Github, we also support some third-party services:

  • TravisCI. TravisCI is free to use for open source projects, but you should be aware that it limits to 5 the number of executors per organizations. It means that only 5 builds can run concurrently in any organization. If your repositories are part of the Eclipse organization, you may face long delays between the trigger and the actually start of the job. If it's your case, and would like to stick to TravisCI for building, we suggest you ask to move to a dedicated organization.


We do not support

If an environment is not listed in the unsupported list, you can ask whether it can be supported by opening a bug.

Third party build services (e.g., Travis) limitations
The Eclipse Foundation's IT Team is responsible for the credentials (OSSRH, SSH and GPG keys...) it creates for projects. Keeping track of where credentials are disseminated is crucial for security reasons. As long as we have no automation in place to set/update/remove credentials on 3rd party build services, we don't put any credential on such services. For instance, it means that you can't use them to publish to Maven Central, or to upload build results to download.eclipse.org.


Docker Hub

The Eclipse Foundation owns the eclipse organization and a couple of other project specific organizations at https://hub.docker.com. You can ask to get a repository being created on one of these organizations. We will set permissions so that committers have write access to this repo (you will need to share your Docker Hub ID with us).

We can also ask us to create a project specific organization. The organization name needs to follow the pattern eclipse<projectname>.

Note that we don't grant admin permissions on any Eclipse Foundation owned organization. We recognize that this means that you will have to go through us for all new repo creation, but we can't grant organizations-wide admin permission assigned to committers for security reasons.

Nexus/Maven repository

Signing tool

Eclipse Platform / plugins specific tooling

CBI license bundle

We offer a P2 repository containing the `org.eclipse.license` bundle which is located at:

   http://download.eclipse.org/cbi/updates/license/

This URL is a composite P2 repo containing the license bundle.

If you use Tycho you can add the p2 repo to the <repositories> section of your pom.xml file. Something similar to this:

    <repository>
      <id>license-feature</id>
      <url>http://download.eclipse.org/cbi/updates/license/</url>
      <layout>p2</layout>
    </repository>

In any particular feature which you need the license you can use the usual feature.xml section:

<?xml version="1.0" encoding="UTF-8"?>
<feature
      id="org.eclipse.help"
      label="%featureName"
      version="2.0.0.qualifier"
      provider-name="%providerName"
      plugin="org.eclipse.help.base"
      license-feature="org.eclipse.license"
      license-feature-version="1.0.0.qualifier"/> 
....

p2 repo checks

A set of "tests" which create reports or can be ran as unit tests that check to correctness of p2 repositories. That is partially just "correctness" in general (such as, that jars are signed, etc.) but more so that repositories conform to the requirements of the Eclipse Simultaneous release (such as, that jars have correct "Provider names", licenses, etc.). For more information, see See CBI/p2repoAnalyzers/Repo Reports.

p2 repo aggregator

A tool to combine several p2 repositories. Among other things, it makes sure they all have consistent constraints (that is, can be "installed together") unlike a raw p2 mirror task. For more information see CBI/aggregator.
