How to resolve "Only one project can be specified" error from <msbuild> task in CruiseControl.NET

Question

I'm trying to use the task in CruiseControl.NET version 1.3.0.2918 with a rather straight forward :

  <project name="AppBuilder 1.0 (Debug)">
    <workingDirectory>c:\depot\AppBuilder\1.0\</workingDirectory>
    <triggers/>
    <tasks>
      <msbuild/>
    </tasks>
   </project>

However, when the project is run it fails with this information in the build log:

MSBUILD : error MSB1008: Only one project can be specified. Switch: 1.0

For switch syntax, type "MSBuild /help"

When I look at the ccnet.log file I find this:

Starting process [C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe] in working directory [c:\depot\AppBuilder\1.0] with arguments [/nologo "/p:CCNetArtifactDirectory=C:\Program Files\CruiseControl.NET\server\AppBuilder 1.0 (Debug)\Artifacts;CCNetBuildCondition=ForceBuild;CCNetBuildDate=2009-01-22;CCNetBuildTime=09:25:55;CCNetIntegrationStatus=Unknown;CCNetLabel=3; CCNetLastIntegrationStatus=Failure;CCNetNumericLabel=3;CCNetProject=AppBuilder 1.0 (Debug);CCNetProjectUrl=http://CISERVER01/ccnet;CCNetRequestSource=jstong; CCNetWorkingDirectory=c:\depot\AppBuilder\1.0\" "/l:ThoughtWorks.CruiseControl.MsBuild.XmlLogger,ThoughtWorks.CruiseControl.MsBuild.dll;C:\Program Files\CruiseControl.NET\server\AppBuilder 1.0 (Debug)\Artifacts\msbuild-results.xml"]

from which I infer that msbuild was run in the correct working directory and that the command line passed to it was:

/nologo "/p:CCNetArtifactDirectory=C:\Program Files\CruiseControl.NET\server\AppBuilder 1.0 (Debug)\Artifacts;CCNetBuildCondition=ForceBuild;CCNetBuildDate=2009-01-22;CCNetBuildTime=09:25:55;CCNetIntegrationStatus=Unknown;CCNetLabel=3; CCNetLastIntegrationStatus=Failure;CCNetNumericLabel=3;CCNetProject=AppBuilder 1.0 (Debug);CCNetProjectUrl=http://CISERVER01/ccnet;CCNetRequestSource=jstong; CCNetWorkingDirectory=c:\depot\AppBuilder\1.0\" "/l:ThoughtWorks.CruiseControl.MsBuild.XmlLogger,ThoughtWorks.CruiseControl.MsBuild.dll;C:\Program Files\CruiseControl.NET\server\AppBuilder 1.0 (Debug)\Artifacts\msbuild-results.xml"

If I run this manually at the command line I get a similiar error.

It appears to me that the isn't passing the correct command line to the MSBuild executable.

Can you spot my error? Or is this version of CruiseControl.NET (1.3.0.2918) broken with respect to the task?

Answer 1

Why is your msbuild tag empty? It should be something similar to:

<msbuild>
  <executable>C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe</executable>
  <workingDirectory>C:\dev\ccnet</workingDirectory>
  <projectFile>CCNet.sln</projectFile>
  <buildArgs>/noconsolelogger /p:Configuration=Debug /v:diag</buildArgs>
  <targets>Build;Test</targets>
  <timeout>900</timeout>
  <logger>C:\Program Files\CruiseControl.NET\server\ThoughtWorks.CruiseControl.MsBuild.dll</logger>
</msbuild>

Without more detail since you don't appear to be specifying a project/solution file which leaves MSBuild assuming one. If you have more than one file that MSBuild is able to use as a project file in that directory that might be causing your issue.DO you have an MSbuild .proj and a .sln file by any chance? Or two solution files?

I think maybe it is your space in the artifact directory path. MSBuild really does not like spaces as it considers it a break between arguments. Can you try an remove the space from that path and see what happens?
