[ccnet-user] "Source control failure (GetModifications)" with Mercurial

[Jesse McGrew]

Hi, I'm trying to set up CruiseControl.NET 1.5.7256.1 for automatic
builds. My project is stored in Mercurial, and I'm using the 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 I force a build, I get this error:

[Slider:WARN] Source control failure (GetModifications): Source
control operation failed: < was unexpected at this time.
. Process command: C:\Python26\Scripts\hg.bat log -r 0:123 --template
<modification><node>{node|short}</node><author>{author|user}</

email><files>{files}</files></modification> --noninteractive
[Slider:INFO] Integration complete: Exception - 12/2/2010 1:19:08 PM

The error is presumably caused by the unquoted angle brackets in the --
template parameter, but how can I make CC.NET put quotes around that
parameter?
