Setting GIT_SSH programmatically [message #1817156]

Hi!

I'm getting a org.eclipse.jgit.api.errors.TransportException with an "invalid privatekey:" text when trying to use JGit and a simple call such as:

        Git(repository).fetch().call()

As I found online somewhere, setting the `GIT_SSH` environment variable to ssh solves this problem and works perfectly. However, I would like to do this programmatically in the app. Is there a way to do this?

Regards, Simon

JGit reads the environment of the Java process it's running in using System.getenv("GIT_SSH").
Java does not provide a setter to set environment variables from Java.

It may be possible to hack that by using reflection but I wouldn't recommend this since it is most likely not
portable between different OSes and Java versions.

Right, thanks! So,. there is no other way to achieve this at the moment? I'm trying instead to replicate it by using my own RemoteSession implementation that basically does what (the private class) ExtSession does but always uses "ssh" as a transport, but haven't gotten it to work so far.

You could try installing your own SystemReader instance that overrides getenv() to return whatever the full path to the SSH executable is when asked for "GIT_SSH".
