Description Owain Jones

Build Identifier: 20110916-0149

I have a fairly complicated setup on this Windows machine, so that probably doesn't help: I have msysgit and TortoiseSVN installed, along with vanilla versions of putty/plink.exe and the openSSH binaries.

When I installed Egit, my GIT_SSH variable was already pointing to TortoisePlink.exe, so I assume it had been configured when I installed TortoiseSVN.

Running plink -i <my SSH key> git@wherever.com from commandline works, so I believe it's a bug with EGit. I've configured my Eclipse to look for "id_rsa" and "id_rsa.ppk" (the PuTTy format of the private-key file) within the right directory (my user/.ssh folder) but when performing a push from Egit, it doesn't seem to correctly pass these files to plink, so pushing to e.g. github fails with the message
"No supported authentication methods available"

As a workaround, I've written a 'wrapper' batch file which runs plink.exe with the correct private key:
----
@ECHO OFF
C:\plink.exe -i C:\Users\me\.ssh\id_rsa.ppk %*
----
And set my GIT_SSH to point to that batch file. This works fine - I can now push/pull to my github repo when I use the wrapper file. But obviously that's messy and ignores Eclipse's SSH configuration. 

Reproducible: Always

Steps to Reproduce:
1. Install TortoiseSVN or normal PuTTy package if not already installed
2. Install EGit straight from the Eclipse Marketplace (currently at version 1.2.0.201112221803-r)
3. Generate id_rsa/id_dsa keys for use with PuTTy - different format to the ones Eclipse generates, using puttygen.exe
4. Configure local git repo within Eclipse, attempt to push remote to GitHub repo
5. Before "push ref specifications" dialogue appears, error should pop up (from plink itself) with the message "No supported authentication methods available (server sent: publickey)"
