ASF GitHub Bot commented on SCM-513:
------------------------------------
jira-importer opened a new issue, #730:
URL: https://github.com/apache/maven-scm/issues/730
**[Benjamin
Bentmann](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=bentmann)**
opened
**[SCM-513](https://issues.apache.org/jira/browse/SCM-513?redirect=false)** and
commented
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.
