ScyJava does not pick up the correct dependencies

[egonw]

Eclipse had a dependency issue which they recently fixed, removing archives from Maven Central. Bacting 0.0.40 was updated, giving the fixed dependency tree:

[INFO] |  \- io.github.egonw.bacting:bioclipse-core:jar:2.8.0.16:compile
[INFO] |     +- org.eclipse.platform:org.eclipse.core.runtime:jar:3.25.0:compile
[INFO] |     |  +- org.eclipse.platform:org.eclipse.osgi:jar:3.18.0:compile (version selected from constraint [3.17.0,4.0.0))
[INFO] |     |  +- org.eclipse.platform:org.eclipse.equinox.common:jar:3.16.100:compile (version selected from constraint [3.16.0,))
[INFO] |     |  +- org.eclipse.platform:org.eclipse.core.jobs:jar:3.13.0:compile (version selected from constraint [3.13.0,4.0.0))
[INFO] |     |  +- org.eclipse.platform:org.eclipse.equinox.registry:jar:3.11.100:compile (version selected from constraint [3.11.0,4.0.0))
[INFO] |     |  +- org.eclipse.platform:org.eclipse.equinox.preferences:jar:3.10.1:compile (version selected from constraint [3.10.0,4.0.0))
[INFO] |     |  |  \- org.osgi:org.osgi.service.prefs:jar:1.1.2:compile (version selected from constraint [1.1.0,1.2.0))

Here, org.eclipse.platform:org.eclipse.equinox.preferences:jar:3.10.1 is the fixed library (see eclipse-equinox/equinox.bundles#54), but when installing pybacting it still depends on 3.10.0:

[Error: ] Failed to execute goal on project managers-inchi-BOOTSTRAPPER: Could not resolve dependencies for project 
io.github.egonw.bacting-BOOTSTRAPPER:managers-inchi-BOOTSTRAPPER:jar:0: Failed to collect dependencies at

No versions available for org.osgi.service:org.osgi.service.prefs:jar:[1.1.0,1.2.0) within specified range -> [Help 1]

Note how it does pick up org.eclipse.platform:org.eclipse.core.runtime:jar:3.25.0 but then is happy with the broken org.eclipse.platform:org.eclipse.equinox.preferences:jar:3.10.0 where version 3.10.1 should be used instead.

This leaves pybacting uninstallable for now. It is yet unclear how to fix this.

Okay, this problem is fixed in Bacting 0.42. The solution there is to explicitly exclude the (non-versioned) org.eclipse.equinox.preferences from the org.eclipse.core.runtime dependency, and the include org.eclipse.equinox.preferences with version 3.10.1 instead. It's a unwelcome workaround, but works.
