Bootstrapping Buckminster & Subclipse with P2 Director

On my current project at work, we are changing from using PDE-Build to create our Eclipse RCP product to using Buckminster. I found a very valuable tutorial to get me started, but I kept getting exceptions like these:


ERROR: Could not instantiate provider org.tigris.subversion.subclipse.core.svnnature for project com.foo.

The solution is to install subclipse, but doing so within Buckminster is painful because you can only specify a single repository location from the command line. Subclipse has a lot of dependencies that already exist in a default eclipse install, but are missing from buckminster-headless, so I needed to specify multiple repositories.

p2 director to the rescue!

In the tutorial, there is a section on bootstrapping buckminster with p2 director. The tutorial loads just the buckminster command-line application from p2 and then uses the buckminster command-line application to load more features into itself. This is convenient when all features and dependencies exist within a single repository, but as I said above, this is not my situation.

Assuming you are using bash and have p2 director installed, here is the command:


director/director\
-r http://download.eclipse.org/tools/buckminster/headless-3.6,http://download.eclipse.org/releases/helios/,http://subclipse.tigris.org/update_1.6.x\
-d `pwd`/buckminster-headless-3.6/\
-p Buckminster\
-i org.eclipse.buckminster.cmdline.product\
-i org.eclipse.buckminster.core.headless.feature.feature.group\
-i org.eclipse.buckminster.pde.headless.feature.feature.group\
-i org.tigris.subversion.subclipse.feature.group\
-i org.tigris.subversion.clientadapter.svnkit.feature.feature.group
