Hello,

I'm trying to get JGit working in Android, and am having problems.

When I try to do a clone from an http repository the actual fetch part fails with errors to do with com.jcrafj.jsch.

Is com.jcrafj.jsch a required library?
What else is a required library?

Or does anyone have any pointers for JGit and Android guides?

Thanks in advance,
James

Ah, it does need the com.jcrafj.jsch library! Altho I'm now getting a different error:

10-17 18:47:29.105: W/System.err(315): org.eclipse.jgit.api.errors.TransportException: <URL>: -1 null

com.jcrafj.jsch is required to support ssh protocol. Find dependencies for org.eclipse.jgit in the manifest
https://git.eclipse.org/c/jgit/jgit.git/tree/org.eclipse.jgit/META-INF/MANIFEST.MF

Hey James,

Before I jump in and try this myself, would you be able to post instructions describing how you got it installed and running? Just looking to save myself (and potentially others) some time.

Thanks

I didn't. I got stuck on the 2nd error above and haven't had time to return to this project since. I'd like to try again sometime, but no idea when. Any ideas appreciated.
