This blog entry only makes sense if you've read Chapter 14 of the Bucky Book.

I have a Mac Book Pro with Snow Leopard. I tried with both Eclipse 3.5.1 and Eclipse 3.6M4. It works with neither. It does work, however, with Linux (Ubuntu) and Eclipse 3.5.1. I haven't tried Eclipse 3.6M4 on Linux.

Installation Issues

There's something going on with installation that I don't understand. I think of the Buckminster installation as having three steps.

• Buckminster from http://download.eclipse.org/tools/buckminster/updates-3.5 This is described as “The Core Buckminster distribution with commonly used feaures.”
• Headless SVN Subclipse client from http://download.cloudsmith.com/buckminster/external/ This is described as “This feaure provides headless SVN integration for Buckminster.”
• Buckminster SVN Support (Subclipse) from http://download.eclipse.org/tools/buckminster/updates-3.5 This is descibed as “Buckminster Support for Subclipse. In order to use feaaures in this category, you must first install Subclipse."

Why is the headless SVN Subclipse client from the cloudsmith site and not from eclipse.org? The Bucky Book refers to the software as

The headless integrations for Subclipse and Subversion contain plug-ins has licenses which prohibits them from being redistributed from Eclipse.org. Instead, we distribute them from Cloudsmiths website. The update site can be found at http://download.cloudsmith.com/buckminster/external. (page 233)

When I worked with Eclipse 3.6M4, I used the site http://download.eclipse.org/tools/buckminster/updates-3.6 instead of http://download.eclipse.org/tools/buckminster/updates-3.5

Now I cannot install all three of the above into the same eclipse.

I cannot install both the Buckminster SVN Support (Subclipse) from http://download.eclipse.org/tools/buckminster/updates-3.5 and the headless SVN Subclipse client from http://download.cloudsmith.com/buckinster/external. This problem does not depend on the order in which I install them.

To get the exmple to work I need Buckminster and the headless SVN Subclipse client.

Buckminster, headless SVN Subclipse client, Buckminster SVN Support (Subclipse)

If I install Buckminster, then the headless SVN Subclipse client, and then try (fail) installing Buckminster SVN Support (Subclipse), I get the following error.

Cannot complete the install because of a conflicting dependency.

What I need for the example

The example consists of creating an rmap and a cquery and then bringing up the cquery in the Component Query Editor and selecting Resolve and Materialize. For this Resolve and Materialize to work I need Buckminster and the headless SVN Subclipse client installed.

If I install just Buckminster and Buckminster SVN Support (Subclipse) and try to Resolve ad Matrialize, I get an the following error.

ERROR [0001] : No suitable provider for component org.demo.hello.xml.world was found in resourceMap http://www.eclipse.org/buckminster/samples/rmaps/demo.rmap

Results of running the example

First of all, note that I am installing Buckminster and the headless SVN (Subclipse) client. To run the example, you must Resolve and Materialize the cquery. Three projects are created: org.demo.hello.xml.world, org.demo.xml.provider, and org.demo.worlds. Then, run org.demo.hello.xml.world as an Eclipse application.

If I do this on my Mac with Eclipse 3.6M4, I get the following error when I try to Resolve and Materialize.

If I do this on my Mac with Eclipse 3.5.1, I can Resolve and Materialize, but I fail when I try to run the example as an Eclipse application. I get the following error. This may not be so unreaonable because the Mac is a 64-bit machine.

If I do this on Linux with Eclipse 3.5.1 (my Linux is running vitutally on my Mac under Parallels), it actually works. Here's what the example look like when running in the runtime workbench as an Eclipse application.

Reproducing the example

If I delete (projects and contents) of the three created projects and then Resolve and Materilize, I get the following error.

ERROR [0001] : CSpec se.tada/tada-sax has no action, group, or local artifact named java.binary.archives
CSpec se.tada/tada-sax has no action, group, or local artifact named java.binary.archives
TAG-ID 0001 = Query for org.demo.hello.xml.world

Can I fix this? Sort of. I tried first by reinstalling Eclipse, but this did not solve the problem. If I delete the workspace and make a brand new one, even remaking the project with its rmap and cquery files, the example works. Apparently just deleting the projects is not enough. Even going into the workspace directory and cleaning it out with command lines apparently is not enough.
