TFS Build Definition deletes itself

Question

In TFS2010 I am having trouble creating Build Definitions.

I have created a new Team Project, added the Solution to the Team Project and am now trying to create a Build Definition.

I click New Build Definition in Team Explorer set the drop folder under Build Defaults and select Continuous Integration under Trigger.

I leave everything else as default and save the definition.

Next I click View Builds and try to queue a build only to get the error message:

TF42036: There is no build definition available to build the team project Project.Title. Create a new build definition and try again.

In the Solution Explorer, the Build Definition has disappeared (it was there previously).

Even more strange, when trying to add another Build Definition, the Process item has a warning icon against it and no Process Templates are available in the drop down list.

Is this a know issue or am I missing something?

Answer 1

You need to select a Build Process Template, the basic one is called DefaultTemplate.xaml and should be in a folder called BuildProcessTemplates under source control. If it's not in the drop down list try clicking the New button, Select an Existing XAML File and browsing for it.

You will also need to specify at least one project/solution under the Items To Build when using the default template.

I solved this by restarting TFS.
