I hope this is the proper area but if not if an administrator could move the thread I would be grateful. Simply put is the expectation that the current Buckminster headless update site should work with Eclipse 3.7.2?
It seems that there is some kind of conflict with Buckminster and Equinox 3.7.2 around Simple Configurator. Equinox 3.7.2 appears to have 1.0.200.v20110815-1438 but the Buckminster update site has 1.0.200.v20110502-1955 which results in an error during installation.
The steps to reproduce:
- Download Eclipse 3.7.2 for Java Developers
- Launch Eclipse. Install New Software. Add Buckminster Headless site for Eclipse 3.7. Select Buckminster product
I know the Buckminster site says to use the director for the headless product but the steps listed above work perfectly fine under Eclipse 3.7.1.
The full error when those steps are tried with Eclipe 3.7.2:
Cannot complete the install because of a conflicting dependency.

| [buckminster-dev] Buckminster builds and non-greedy optional dependencies? [message #811782 is a reply to message #810522] |

As you know, p2 publisher in Eclipse 3.8 (and 4.2), since Juno M1 now
publishes runtime optional dependencies with "greedy=false".
I plan to do some tests and checks against our "common repo" to see who
might not be doing that, yet, and open bugs, or send notes to cross-project
lists with details and advice. From quick inspection, I already see some
cases of the metadata saying "opposite" things: greedy for a bundle in one
place, but not greedy for same bundle in another place ... which I'm
guessing is "not good" (at least, in most cases). Plus, many places where
optional requirements are still greedy (by default).
When I last posted to cross-project about this issue, the Tycho project
reported back:
"Tycho uses 3.8-based publisher and generates non-greedy optional
dependencies since version 0.13."
So, I am wondering about Buckminster. Once I start to test and document, is
there any advice I could give to projects that use Buckminster based
builds? Such be sure to use a version higher than such and such? Thought
I"d check "in advance" what my advice should be, if any. I'll likely send
the note/bugs next week and hope for Juno M6 we can be relatively "clean".
Your advice and help is kindly appreciated.
Thanks,

Hi David,
The 3.8/4.2 version of Buckminster (due by Juno M6) will also use the new publisher.
