Revision as of 15:40, 16 January 2008 by Bjorn.freeman-benson.eclipse.org (Talk | contribs) (Running Ganymatic On Your Machine)

This page is related to the Ganymede Simultaneous Release.


The Ganymatic is live and running every day. The status & logs are here: http://build.eclipse.org/ganymede/

In addition to sending emails to project release engineers who are responsible for broken builds, there are three 'Eclipse Build' format RSS feeds available for project teams to monitor. More info on feeds: Getting Started Guide, Feed Schema.

Of course, there really is no "build" of Ganymede, but only a copying of what is already available on each project's update site, to a central site.

This central update site, naturally, is http://download.eclipse.org/releases/ganymede/. To get a sneak peek, point your Update Manager at http://download.eclipse.org/releases/ganymede/staging/.

The Projects' Roles

Pre-Project Configuration Files

The pre-project configuration files are stored in the Callisto CVS:


Or, general "read" access via


There is one project:

          <attribute component="org.eclipse.jpt.feature" />
  1. ${downloads}/webtools/milestones/site.xml: The location of the project's update site. It's more efficient to access the site via a file path than a url, but a url will work. ${downloads} refers to the root of the http://download.eclipse.org/ server.
  2. Bjorn Freeman-Benson and bjorn.freeman-benson@eclipse.org: person to notify if this project is responsible for breaking the build. Feel free to have multiple people listed.
  3. org.eclipse.wtp-sc: the unique identifier for this site contribution
  4. org.eclipse.jpt.feature: The feature identifier. One per feature (of course). Features are listed one per <dependency .../> node.
  5. 2.0.0.v200706041905-7C5EGzE9RvTVniSrwnf4TgOPe3e9: The feature version. One per feature (of course). Buckminster (the technology Ganymatic is built on) has a number of ways to specify the version. Most projects will use a single fixed version here, although you can also have an empty string to mean "the latest version found on my update site".
  6. Web and JEE Development: Categories for the Ganymede site.xml file; used to group the features.

Schemas for these files are available at: http://www.eclipse.org/buckminster/schemas/siteContribution-1.0.xsd , http://www.eclipse.org/buckminster/schemas/cspec-1.0.xsd , http://www.eclipse.org/buckminster/schemas/common-1.0.xsd , http://www.eclipse.org/buckminster/schemas/rmap-1.0.xsd

Project Responsibilities

Each Ganymede project's PMC and/or Project Leader is responsible to keep its own *.sc (site contribution) file up to date as the project generates new milestones and release candidates. The project's project leader will probably delegate to the project's release engineer(s).

Obviously, each project's own update site must already exist (and be working) at the file location or url specified in the site contribution file.

Typically, as projects move from milestone to milestone (or release candidate to release candidate) only the version identifiers (e.g. 1.0.0.v200706250000-77--CYQCCz-CoRPCCCH]) in the site contribution file will need to be changed. At other times, features might be added, removed, or renamed:

  • Adding a feature: add new <dependency> and <attribute> nodes
  • Removing a feature: remove the corresponding <dependency> and <attribute> nodes
  • Renaming a feature: change the feature identifier (in two places) (e.g., org.eclipse.jpt.feature).

Each project should post updates on the Ganymede/Signoffs page after each of their Milestone and Release Candidates is released.

TBD: how to trigger a new build and how to sign off that the project M-bits are ready to use.

The Central Ganymatic

As of 2007/10/14, the Ganymede builds are being run once a day at 11pm Eastern, 8pm Pacific, 5am Europe, 11am China.

TBD: how to trigger a new build and how to sign off that the project M-bits are ready to use.

Running Ganymatic On Your Machine


Creating Ganymatic for Build.Eclipse.Org

To create the binaries for Ganymatic:

  1. Start with an Eclipse SDK with the latest version of Buckminster [1] loaded.
  2. Check out the org.eclipse.dash.siteassembler project (/cvsroot/callisto).
  3. Right click on the org.eclipse.dash.siteassembler project and choose Buckminster > Invoke Action... > headless.assembler
    This generates the org.eclipse.dash.siteassembler/bin/buckminster directory
  4. Zip up that directory and put it on build.eclipse.org/~bfreeman/ganymede/buckminster/, and unzip it into the bin/buckminster sub-directory

Additional Requirements and Information

See Europa Build for how last year's build worked.
