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.
