Description

For instance, the command

mvn org.apache.maven.plugins:maven-scm-plugin:1.2:checkout
  -D connectionUrl=scm:svn:https://svn.dev.java.net/svn/hudson/tags/build-timeout-1.5/
  -D checkoutDirectory=test
  -D username=guest -D "password="

fails with

authorization failed: Could not authenticate to server: rejected Basic challenge (https://svn.dev.java.net)

because the issued cmd line is

cmd.exe /X /C "svn --username guest --non-interactive checkout https://...

instead of

cmd.exe /X /C "svn --username guest --password "" --non-interactive checkout https://...

i.e. the empty password is not propagated to the server, making the auth challenge fail.

Note: To reproduce this issue, the svn client's auth cache in auth/svn.simple must be empty. Otherwise, a the cached auth data from a successful login will shadow the issue.
