How to set up SCM/CVS/Maven integration with public key
authentication (need help!)?
I have a <scm> section in a POM that looks something like this:
<scm>
<connection>scm:cvs:ext:myhostname:/cvsroot/repo:module_name</connection>
</scm>
I typically use publickey auth to authentication against this cvs server, although it should accept my password as well.
When I attempt to run 'mvn scm:update', 'mvn release:prepare', or any Maven goal that involves connecting to this scm, I get the following failure:
[INFO] Executing: cmd.exe /X /C "cvs -z3 -f -q update -d"
[INFO] Working directory: C:\Documents and Settings\matt.brown\workspace\projectname
org.netbeans.lib.cvsclient.connection.AuthenticationException: Cannot authenticate. Reason: Publickey authentication failed.

And further down in the stacktrace:

Followed by:
[ERROR] Provider message:
[ERROR] The cvs command failed.
[ERROR] Command output:
I'm running this on a Windows machine, with no cvs executable on the PATH. I do have my public key available under $HOME/.ssh, but it doesn't seem as if cvs/maven/scm is loading it here - as I'm not asked for the keyphrase for it.
So, I have a few questions:
1. How do I properly tell maven when using scm where my public key resides? Do I need to do it explicitly?
2. From the stacktrace, does it look as if this is even the correct error - or is something else going on? I can see traffic exchanged between my machine and the CVS host when I run this command if I use wireshark, so I know some sort of communication is going on.
Thanks

Posted by Matt Brown <Ma...@citrixOnline.com>.
For anyone who runs into this problem in the future:
After downloading the scm plugin source, I discovered that the plugin is using an empty string for the passphrase when authenticating with a public key.
To tell the scm/CVS plugin the correct passphrase to use, you need to set a System property for the key "maven.scm.cvs.java.ssh.passphrase", i.e.
mvn scm:status -Dmaven.scm.cvs.java.ssh.passphrase=<my passphrase>
A little disappointing that the system properties the CVS/SCM plugin uses aren't mentioned in the documentation for the plugin.
