I'm trying to connect bitbucket to jenkins. All the public/private key is configured, firewall is configured, but I keep having this error:

Failed to connect to repository : Command "git.exe ls-remote -h git@bitbucket.org:myrepo/myproject.git HEAD" returned status code 128: stdout: stderr: Load key "C:\\Windows\\TEMP
ssh6081589915199893224.key": invalid format Permission denied (publickey). fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

The credential is set to "Private Key" -> "Enter directly" -> "my key" and my passphrase is setted too.

Why is jenkins trying to get the key from TEMP and not from .ssh inside jenkins' folder?
