Incorrect parsing artifactPattern attribute in a sftp resolver
--------------------------------------------------------------

                 Key: IVY-661
                 URL: https://issues.apache.org/jira/browse/IVY-661
             Project: Ivy
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0-beta-1
         Environment: Developer: Windows XP, jdk1.6.0_02, ant-1.7.0, jsch-0.1.36
SFTP Server: FreeBSD-6.2-RELEASE.
            Reporter: Alexey Kiselev
            Priority: Minor
             Fix For: 2.0.0-beta-1


PROBLEM:

Ivy settings file contains description of resolver:
	<resolvers>
		<sftp name="remote">
			<ivy pattern="sftp://user:password@host:12345/repository/[module]/[module]-[revision].xml"/>
			<artifact pattern="sftp://user:password@host:12345/repository/[module]/[artifact]-[revision].[ext]"/>
		</sftp>
	</resolvers>

Then we try to publish to a repository for the first time on empty server we get a java.io.IOException and a following directory structure created on the server ~user/sftp:/.
Afterwards when we publish for the second time we get following directory structure ~user/sftp:/user:password@host:12435/repository/module/ and successfully published artifact.
During the first run the java.io.IOException caused by creation of a directory with empty name. Creation of the directory with empty name caused by double slash (//) following "sftp:".

SOLUTION:

Solution of this problem is in the patch listed below.
