How can I build a SharePoint 2010 package using command line?

Question

I have a Visual Studio 2010 SharePoint project. If I choose 'Package' from the project menu, a .wsp file is generated. How can I invoke the same build from command line (i.e. what /target is required for MSBuild)?

Answer 1

I got it to work, finally. The tricky part is the fact that the SharePoint targets do not exist when MSBuild loads the .sln file, you have to load the individual .csproj files.

set msbuild="C:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe"
set config=Debug
set outdir="C:\out\"
%msbuild% /p:Configuration=%config% /m ../My.SharePoint.Project/My.SharePoint.Projectcsproj /t:Package /p:BasePackagePath=%outdir%
