Can't find a working ssh client library that will pass karaf-feature-verification

Development

Working on a new ddwrt plugin. trying to build it on ssh. The two ssh client libs I tried seem to depend on deprecated packages

jsch seems to be most popular but it depends on org.newsclub.net.unix which I can’t resolve

tried apache sshd which is used by eclipse but ran into issue with sun.security.x509 see The net.i2p.crypto.eddsa 0.3.0 bundle has bad OSGi metadata · Issue #15 · eclipse-orbit/orbit-simrel · GitHub

Metadata can be amended with wrap protocol (wrap:mvn:…), see:

Its important to mark wrap protocol feature as a prerequisite, once you do that with few (hundreds) attempts you might be able to pass validation.

I tried several different ways and nothing works

<?xml version="1.0" encoding="UTF-8"?>
<features name="org.openhab.binding.ddwrt-${project.version}" xmlns="http://karaf.apache.org/xmlns/features/v1.4.0">
	<repository>mvn:org.openhab.core.features.karaf/org.openhab.core.features.karaf.openhab-core/${ohc.version}/xml/features</repository>

		<bundle>wrap:mvn:org.apache.sshd/sshd-osgi/2.14.0&amp;overwrite=merge&amp;Import-Package=!org.apache.tomcat.*,*</bundle>
		<bundle start-level="80">mvn:org.openhab.addons.bundles/org.openhab.binding.ddwrt/${project.version}</bundle>
	</feature>
</features>

The first part after mvn: url should be dollar sign. Rest of it looks fine. Try this: <bundle>wrap:mvn:org.apache.sshd/sshd-osgi/2.14.0$overwrite=merge&amp;Import-Package=!org.apache.tomcat.*,*</bundle>

Thanks I got a little further but stuck on org.apache.tomcat.jni

Are you sure you need it? Your binding, or one of dependencies you embedded in it, is trying to make use of it.
