continuous integration - How to get CruiseControl.NET working with Mercurial: "Source control failure (GetModifications)" -

i'm trying set cruisecontrol.net 1.5.7256.1 automatic builds. project stored in mercurial, , i'm using following ccnet.config:

<cruisecontrol xmlns:cb="urn:ccnet.config.builder">     <project name="slider" weburl="http://localhost/ccnet">         <triggers>             <intervaltrigger seconds="3600" />         </triggers>         <sourcecontrol type="hg" autogetsource="true">             <executable>c:\python26\scripts\hg.bat</executable>             <repo>c:\repos\slider</repo>             <workingdirectory>c:\ccnet\slider</workingdirectory>         </sourcecontrol>         <tasks>             <msbuild>                 <executable>c:\windows\microsoft.net\framework64\v4.0.30319\msbuild.exe</executable>                 <workingdirectory>c:\ccnet\slider</workingdirectory>                 <projectfile>slider.sln</projectfile>                 <buildargs>/noconsolelogger /p:configuration=debug /v:diag</buildargs>                 <targets>slider</targets>                 <timeout>900</timeout>                 <logger>c:\program files (x86)\cruisecontrol.net\server\thoughtworks.cruisecontrol.msbuild.dll</logger>             </msbuild>         </tasks>     </project> </cruisecontrol> 

but when force build, error:

[slider:warn] source control failure (getmodifications): source control operation failed: < unexpected @ time. . process command: c:\python26\scripts\hg.bat log -r 0:123 --template <modification><node>{node|short}</node><author>{author|user}</author><date>{date|rfc822date}</date><desc>{desc|escape}</desc><rev>{rev}</rev><email>{author|email|obfuscate}</email><files>{files}</files></modification> --noninteractive [slider:info] integration complete: exception - 12/2/2010 1:19:08 pm 

the error presumably caused unquoted angle brackets in --template parameter, how can make cc.net put quotes around parameter?

===============

here's hg.bat:

@echo off rem windows driver script mercurial  setlocal set hg=%~f0  rem use full path python (relative script) standard python rem install not put python.exe on path... rem %~dp0 directory of script  %~dp0..\python "%~dp0hg" %* endlocal 

i'm using cruisecontrol.net 1.5.7256.1 mercurial installed msi, using full path of hg.exe executable value.

in project\core\sourcecontrol\mercurial\mercurial.cs template used this:

buffer.addargument("--template", historytemplate) 

and formatted command line this:

string.format("{0}{1}{2}", arg, separator, stringutil.autodoublequotestring(value)) 

where separator " ", , autodoublequotestring quote template, can't cause of error.

update 1

actually, autodoublequotestring should quote template, in current version doesn't it. also, if build succeeds when using hg.exe, running actual command line in command prompt returns same error.

update 2

cruisecontrol.net 1.6.7981.1 released (see release notes), , since template passed file, works fine (at least on pc).
