Thanks for writing the Bazaar plugin for Hudson!  I'm trying it out
for bzr-p4 (https://edge.launchpad.net/bzrp4).  I have a Hudson job
that gets code from Bazaar and runs my tests, and I can trigger it
manually.

I haven't been able to get polling working.  In the Hudson UI, I see:

In the console window where I started Hudson, I see:

Here's how I set up my Hudson job:

1. Download Hudson 1.255 from
   https://hudson.dev.java.net/servlets/ProjectDocumentList?folderID=2761&expandFolder=2761&folderID=0

2. Download/install Bazaar 1.8 Windows installer from
   https://launchpad.net/bzr/+download .  Add Bazaar to PATH.

3. Download/install bzr-xmloutput from lp:bzr-xmloutput via bzr branch.
   See http://bazaar-vcs.org/XMLOutput .

4. java -jar hudson.war . Point browser at http://localhost:8080/ .

    Note: maybe need larger heap size.  -Xmx1024m ?

5. Download Bazaar plugin for Hudson from
   http://verterok.com.ar/bzr-hudson/bazaar.hpi .  Install via Hudson web
   UI.

6. New Job in Hudson.  Job name = bzrp4, e.g.  Build a
   free-style software project.

7. Advanced Project Options > Use custom workspace.  Directory =
   C:\Documents and Settings\mlm\.hudson\jobs\bzrp4\workspace\bzrp4 , i.e.,
   a path ending in "bzrp4".  Otherwise, Hudson uses the path ending in
   "workspace".  That doesn't work because bzr selftest relies on loading
   the bzrp4 plugin from a path ending in "bzrp4".

8. Source Code Management > Bazaar.  Branch URL =
   /home/mlm/sandbox/bzr-p4/bzr/continuous.integration.windows .  I tried
   C:\home\... but it didn't work because Hudson's URL parsing rejected the
   URL containing backslashes.

9. Build > Add build step > Execute Windows batch command .  Command =
   ci.selftest.bat .
