I've made an MSBuild project that simply does an msbuild task with our solution file as parameter. I've defined a BeforeBuild target where I set some properties, and a Build target that executes the msbuild task.

I've confirmed that no errors occured when building the msbuild script in the command line console. However, when I use it in the msbuild task in my CCNET project, I keep getting the following error:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets (483,9): error: The OutputPath property is not set for project 'MyProject.msbuild'. Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Configuration='Debug' Platform='AnyCPU'. You may be seeing this message because you are trying to build a project without a solution file, and have specified a non-default Configuration or Platform that doesn't exist for this project.

I checked the build log and it seems that the error occurs during _CheckForInvalidConfigurationAndPlatform. It wasn't even able to continue to my Build task! Since the script is only intended to build the solution under Debug/Release and AnyCPU as platform, I tried to add the following lines to my msbuild project:

<PropertyGroup Condition=" '$(Configuration)|$(Platform)' ==  'Debug|AnyCPU' ">
  <OutputPath>.\bin\Debug\</OutputPath>
</PropertyGroup>
<PropertyGroup Condition=" '$(Configuration)|$(Platform)' ==  'Release|AnyCPU' ">
  <OutputPath>.\bin\Release\</OutputPath>
</PropertyGroup>

I could still build the project without errors in the command line, but CCNET is returning the same error mentioned above.

I don't understand why CCNET keeps getting the error, and I don't know what else to try.

Please help.
