Creating a K2 Deployment Package from code

下面这篇文章介绍了如何通过编程的方式生成K2的部署包

http://cyclops.nettrends.nl/blog/2008/05/creating-a-k2-deployment-package-from-code/

In our current project, we are using Tean Foundation Server to automate our build process. This also means MSI’s are created for every artifact to deploy, eventually using TFS’s functionality to deploy a new msi when the build quality is changed. MSI’s are build in a way so they can be installed from command line without user actions required (unattended installation). So, when we change the build quality of a build it can fully automatically be deployed to a testing environment.

Most of our software that needs to be deployed are webservices, websites or web parts. K2 however, is somewhat harder to deploy. Since BlackPearl it has become a lot easier because you can use a MSBUILD command to deploy a process. For those of you who don’t know about this. Check out KB000188 at the K2 Knowledge base. In general, it comes down to this command:

MSBUILD DeploymentPackage.msbuild /p: Environment=Development

It’s easy to create a MSI or (PowerShell) script that starts the MSBUILD command and installs the process. But how do we automate the creation of the deployment package? Since this is normally done from VS2005.

 

实际上，主要用到了两个方法

Sourcecode.Framework.ProjectSystem.Project.CreateDeploymentPackage

Project.Save

完整的代码如下
