Subversion provider doesn't handle tag updates correctly
--------------------------------------------------------
Key: SCM-68
URL: http://jira.codehaus.org/browse/SCM-68
Project: Maven SCM
Type: Bug
Components: maven-scm-provider-svn
Versions: 1.0-alpha-4
Reporter: David Hawkins
Attachments: update-switch.patch
When attempting to use Continuum I kept having problems where Continuum would
checkout the project fine, but always fail to update it on subsequent builds.
Continuum forces you to specify a scmTagBase as well as a scmTag for subversion
projects. The problem is that is passes the tag to the scm update which ends
up issuing a svn command with -r tagname
Example:
checkout command:
svn --non-interactive checkout
http://svn/projects/dmi-jdbc/branches/my-branch-name 6
update command
svn --non-interactive update -r branches/my-branch-name
This probably works fine in cvs because a tag can refer to a revision or tag.
In subversion, tags and revisions are obviously very different so the
SvnUpdateCommand should handle the two cases differently if you are requesting
a revision or an actual tag.
I've created a patch which corrects the problem and causes SvnUpdateCommand to
perform a switch to update whenever a non revision tag is specified. I believe
this will produce the intended results, but I am also fairly new to subversion
and its possible it doesn't.
Please let me know if you need more information.
