------------------------------------
Summary: GIT clone inexplicably fails on MAC: Incorrect
Credentials even though credentials are valid
Key: NETBEANS-5852
URL: https://issues.apache.org/jira/browse/NETBEANS-5852
Project: NetBeans
Issue Type: Bug
Components: versioncontrol - Git
Affects Versions: 12.4
Reporter: Scott Oaks
Trying to git clone a repository on my Mac, using credentials (user/private
key) that work from the git command line, and I continually get
Incorrect credentials for repository at ...
There is no other information to help me here, which is the first problem. It
would be very helpful to print out the stack trace to let me know more about
the kind of problem I've encountered.
Eventually I resorted to building netbeans myself so I could insert the needed
diagnostics, which were that the Jsch didn't like my private key:
{code:java}
[exec] Caused by: com.jcraft.jsch.JSchException: invalid privatekey:
[B@3e2f8dbf

[exec] ... 28 more {code}
A little more research and I discovered that JSch doesn't like keys with the
header of
-----BEGIN OPENSSH PRIVATE KEY-----
Instead they require
-----BEGIN RSA PRIVATE KEY-----
Mac key generation defaults to the first one; the second can be forced by
generating keys with
ssh-keygen -t rsa -m PEM
And so using that key works.
So two things:
1) Better diagnostics in failure case
2) Support all valid keys on mac (especially the default key)
