CBI

(Redirected from Common Build Infrastructure)

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

Goals

Primary goals of the CBI initiative are:

  • Make it really easy to contribute Eclipse projects
    • Make it really easy to copy & modify source
    • Make it really easy to build
    • Make it really easy to test
    • Make it really easy to post a change for review
    • Make it really easy to sign software

Secondary goals are:

  • Get all Eclipse projects building their software on Eclipse Foundation hardware.
  • Make it easy for people to build custom Eclipse distributions.

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.

Preferred Build Technologies

CI Environment (Jenkins)

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

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

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) 3.75G/30G Linux Virtual Server (if needed) (courtesy of Microsoft Azure)
  • 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.

  • Some resources are only available to Enterprise and Strategic members.
  • Enterprise and Strategic members can engage with the Foundation to acquire additional Packs.

Resource Packs Included in Membership

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

Assigning Resource Packs to a Project

Resource Packs are assigned by Eclipse Members to Eclipse Projects they sponsor (Members 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.

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.


Maven

Maven 3.x drives the builds. Projects are expected to provide standard Maven 3.x POM files for their builds. The builds should be built in such a way that they can be run on the local workstation, or on the Eclipse build server. Note that builds can only be signed on the Eclipse build server.

Tycho

Tycho is focused on a Maven-centric, manifest-first approach to building Eclipse plug-ins, features, update sites, RCP applications and OSGi bundles.

p2 Repo checks

It's highly recommended that any Eclipse.org project runs frequently, and maybe even systematically, the p2 repo analyzer to make sure it conforms to some requirements of being a nice citizen in the Eclipse.org world.

Nexus

See Services/Nexus.

Signing tool

Deliverables

Additionally to recommendation and infrastructure, the CBI also produces pieces of software that are meant to be commonly used by all Eclipse.org projects.

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 are using 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"/> 
....

Signing tool

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.
