Marketplace install fails with no error

Running latest openhab-addons from Eclipse IDE, if I try to install the OpenWebNet Binding (Beta) from Marketplace, it returns an error on the GUI:
Installation of add-on 129775 failed
but no error on the log, and the binding is not installed.

How can I try to understand what is wrong?

If i try to install other bindings, for example Samsung TV Bindin (Beta), they get installed, but receive this error for unsatisfied dependency:

WARN  [OH-addonService-2   ] [ace.MarketplaceBundleInstaller:94   ] - The marketplace bundle was successfully installed but doesn't start: Could not resolve module: org.openhab.binding.samsungtv [166]
  Unresolved requirement: Import-Package: org.openhab.core.config.discovery.upnp

OpenWebNet Binding (Beta)

Looks like this addon is packaged as a KAR which will only work with a real Karaf instance and not the build-in Eclipse IDE OSGi environment.

Samsung TV Binding (Beta)

You can probably fix this issue by adding the org.openhab.core.config.discovery.upnp bundle to the runbundles before you start openHAB in the IDE.

Ok, so If I provide just the .jar in the Marketplace post, it should install also from IDE, but in that case users with a regular OH install will not be able to solve the dependencies automatically, correct?

Correct. What I usually do is running a regular openHAB in debug mode (start_debug.sh/start_debug.bat) and attach a debugger to that via remote debugging (port 5005).
