Cannot authenticate with ed25519 ssh key

[FedeHAL]

I've created an ed25519 for gitlab authentication. but it doesn't seems to work:

invalid privatekey: [B@15b0e7f3

If I test it on the rundeck server from command line it works OK.

I've tried in other rundeck instances with rsa keys and it works.

I'm faced with the same problem, can't use an ed25519 key, but RSA works fine.

[pvillanue]

RSA1 keys have been disabled from GitHub Enterprise for security reasons, and to use HTTPS with a username is not the cleanest solution.
Any key format raises the same message (invalid privatekey).

May be, it's enough to update the dependencies of the components to a later version and rebuild, but my "developer" knowledge is not enough.

@pvillanue Use SSHJ-{SSH|SCP} executors, they do support ed25519.
