I have the same problem, I need the wrap feature, which at some point last year was available.
In the log I can see the details of the error:
2017-01-25 19:01:54.826 [WARN ] [url.mvn.internal.AetherBasedResolver] - Error resolving artifact org.ops4j.pax.url:pax-url-wrap:jar:uber:2.5.2: [Could not find artifact org.ops4j.pax.url:pax-url-wrap:jar:uber:2.5.2 in openhab (https://dl.bintray.com/openhab/mvn/online-repo/2.0/)]
When browsing the repository, the mentioned bundle does not appear, as the error says. Is it something that should be fixed by OpenHAB or should we just add some repository that contains it? (e.g. in userdata/etc/org.ops4j.pax.url.mvn.cfg perhaps?)
Wrap is not “standard” feature any longer and must be embedded to not cause internet scan. Since openhab have different set of remote repositories (bintray) than default Karaf installation it doesn’t work.
As work around please modify etc/org.ops4j.pax.url.mvn.cfg and add to remoteRepositories property http://central.maven.org/ or http://repo1.maven.apache.org/maven2 (both should host the same artifacts) so you will get access to pax-url-wrap.
