How to get AssemblyInfo task to update a single AssemblyInfo file

Question

I'm using CruiseControl.net as my integration server.  I want to set my CommonAssemblyInfo.cs -> AssemblyVersion to 5.0.123 where 123 is the build number provided by CC in the CCNetLabel variable.  I have installed the MSBuild Extensions Pack from CodePlex but I can't suss out how to make it work.

Here's my MSBuild file:

<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <Import Project="$(MSBuildExtensionsPath)\Microsoft\AssemblyInfoTask\Microsoft.VersionNumber.targets"/>


  <Target Name="UpdateCommonAssemblyInfo">
    <ItemGroup>
      <AssemblyInfoFiles Include="CommonAssemblyInfo.cs"/>
    </ItemGroup>
    <AssemblyInfo AssemblyInfoFiles="@(AssemblyInfoFiles)"
                  AssemblyVersion="5.0.$(CCNetLabel)"/>
  </Target>
</Project>

Here's the command I'm using to run it:

msbuild /target:UpdateCommonAssemblyInfo /property:CCNetLabel=123 MyProj.xml

I'm getting an error saying the "input" parameter cannot be null.  Any ideas on what I'm missing here?

Answer 1

CCNetLabel=123 is not a valid input since it missing a delimiter. CCNetLabe="1.2.3" will work though.

You may want to break down the label as follows:

    <AssemblyInfo AssemblyInfoFiles="@(AssemblyInfoFiles)"
                  AssemblyMajorVersion="5" 
                  AssemblyMinorVersion="$(AssemblyMinorVersion)" 
                  AssemblyBuildNumber="$(AssemblyBuildNumber)"
                  AssemblyRevision="$(AssemblyRevision)"/>

Called with:

msbuild /target:UpdateCommonAssemblyInfo /p:AssemblyMinorVersion=1;AssemblyBuildNumber=2;AssemblyRevision=3

Result:

[assembly: AssemblyVersion("5.1.2.3")]

Hi Doug,

The Assembly version is formatted as AssemblyMajorVersion, AssemblyMinorVersion, AssemblyBuildNumber, and AssemblyRevision properties, which should looks like 1.2.3.4. AssemblyVersion is used to modify the entire version, but it still requires the same format. In above sample, your code want to revise the version as 5.0.123 which is not an accepted format.

I run the following code with your command and it works.

  <Import Project="$(MSBuildExtensionsPath)\ExtensionPack\4.0\MSBuild.ExtensionPack.tasks"/>

  <Target Name="UpdateCommonAssemblyInfo">
    
    <ItemGroup>
      <AssemblyInfoFiles Include="AssemblyInfo1.cs"/>
    </ItemGroup>

    <MSBuild.ExtensionPack.Framework.AssemblyInfo 
        AssemblyInfoFiles="@(AssemblyInfoFiles)"  
        AssemblyVersion="5.0.0.$(CCNetLabel)"/>
      
  </Target>
</Project>

If you need to modify the some digit of the version, you may use
AssemblyMajorVersion, AssemblyMinorVersion, AssemblyBuildNumber, and AssemblyRevision directly rather than AssemblyVersion.
