Deployment with wagon-ftp broken
--------------------------------
Key: MNG-594
URL: http://jira.codehaus.org/browse/MNG-594
Project: Maven 2
Type: Bug
Components: maven-core
Versions: 2.0-alpha-3
Environment: Linux proulx.local.net 2.6.8-1.521 #1 Mon Aug 16 09:01:18 EDT
2004 i686 i686 i386 GNU/Linux
Fresh installation of maven alpha 3. All updates accepted.
Reporter: Wilfred Springer
Two days ago, it was still possible to deploy artifacts to a remote repository
using wagon-ftp. (Relevant jar files (wagon-ftp-1.0-alpha-4.jar and
commons-net-1.1.0.jar) added to $M2_HOME/lib.)
That doesn't work anymore:
m2 deploy

The problem is caused (not the root cause though) by the openConnection
operation on FtpWagon:
public void openConnection()
throws ConnectionException, AuthenticationException
{
if ( authenticationInfo == null )
{
throw new IllegalArgumentException( "Authentication Credentials
cannot be null for FTP protocol" );
}
It appears that the authenticationInfo is null, and that the ftp variable
(FtpClient) is never set, which is causing the NullPointerException when the
wagon is trying to disconnect. Don't know what caused it. Note that I also
tried it on the latest HEAD revisions of maven-components en maven-wagon, and I
got exactly the same problem.
