Re: [orbit-dev] Logback slf4j impl 1.0.3 
Hello,

I tried some more changes to logback slf4j bundle, which I supposed could cause a problem, but nothing helped. If this bundle is present the build fails, so I removed it. 
Strangely, it seems as if when logback slf4j 1.0.3 is present, the build could not find logback slf4j 0.9.27, although both should be present - they are in http://build.eclipse.org/orbit/projects/orbit-I/workdir/plugins. 

SLF4J API 1.6.1 has a require capability, which is satisfied by a provide capability of logback slf4j 0.9.27. So when logback slf4j 1.0.3 is present, the build fails saying that it cannot resolve SLF4J API 1.6.1 because it cannot satisfy the require capability. This could happen only if logback slf4j 0.9.27 is missing. When logback slf4j 1.0.3 is not present in the build there are no problems and SLF4J API 1.6.1 resolves correctly.

The build fails with the following error:
[orbit-set1] generateScript:
[orbit-set1] [eclipse.buildScript] Some inter-plug-in dependencies have not been satisfied.
[orbit-set1] [eclipse.buildScript] Bundle ch.qos.logback.slf4j:

David, could you think of something, which could cause such a problem? I could add logback slf4j 1.0.3 once more, so that the build fails again and you could have a look on the logs.

Regards,
Lazar

I tried to add back the bundle with a small modification, but the build failed with the same error - for some reason the build tries to attach it to slf4j.api 1.6.1 and this fails - it should fail. But should not try to do this at all.

No, I left BREE to 1.5, 1.6, 1.7 - I used as base your 1.0.0 version. I only changed the Bundle-Version, as everything else is essentially the same. Then I also changed the start of the version range for the fragment host to 1.6.4 (it was 1.6.1), but with no effect. I was thinking if the problem does not arise because both versions 1.0.0 and 1.0.3 are attached to the same host, but this host is 1.6.4, and no error for 1.6.1 should happen. The build should not at all try  to attach 1.0.3 impl to 1.6.1 api.

Did you change something with the BREE? Maybe there is some Equinox
Wiring issue under the hood?
