CDO Source Installation

Revision as of 06:31, 4 January 2012 by (Talk | contribs) (Create the API Baseline)


This tutorial describes how to install a CDO workspace using Buckminster.
The sources can also be browsed through
Binaries can be downloaded from

Prepare the IDE

Download and install Eclipse 3.7 or 3.8 from

Then open a fresh development workspace.

Select the Indigo (for 3.7) or Juno (for 3.8) p2 repository and install the following features:

  • EMF - Eclipse Modeling Framework SDK
  • Graphical Modeling Framework SDK (needed for CDO Dawn)
  • Eclipse EGit (Team Provider)

Select the Buckminster p2 repository and install the following features:

  • Buckminster - Core
  • Buckminster - Git Support
  • Buckminster - PDE Support

Committers: Please do not forget to install our versioning tool from

Now you have prepared your IDE with the required tools.

Create the API Baseline

Now an API baseline will be created. Non-committers may skip this section.

  • Add the API baseline to Eclipse: Open the Preferences (Window->Preferences) and open the "API Baselines" page.

  • Click "Add Baseline...". Give it the name CDO 4.0 Baseline and choose the path to the folder on your local disk where you've extracted the downloaded baseline to. Then the API baseline is created and set active for your workspace.

Materialize the Sources and the Target Platform

The materialization of the workspace contents (sources and binaries) will be performed by Buckminster with the cooperation of EGit and p2. For EGit to work properly please create the folder ${user.home}/git on your hard disk.

Then start the Buckminster import wizard:

Point it to the Buckminster MSpec of CDO:

For a 4.0 maintenance workspace use instead.

Press the Load button and wait until Buckminster has resolved all the dependencies (go and fetch a coffee, or two, or three).

Finally hit the 'Finish' button

Updating the Workspace

You can update your development workspace by re-importing the local.mpec (right-click + Buckminster + Import...). Then the whole workspace and the target platform are updated.

Note, that re-importing does only add new source projects but doesn't update existing source projects from the Git repository. Use EGit for this purpose!
