Option #1: Add an Exit step configured with an exit status of Failure (to build failure steps) or Cancel (to stop without building failure steps). The step can use a conditional build rule to conditionally abort the build.


Option #2: Use VBScript code of:

Step.BuildStatus = vbldStepStatFailed

in a step script event (accessed by clicking the Script Editor button on the step properties dialog, clicking the Events button, and choosing a step event).


Option #3: Use VBScript code of:

Err.Raise 1, "", "Error message"

or the following Jscript code (note: the error message thrown doesn't get logged for JScript):

throw "Error";

The code can be placed in a script function, the code of a Run Script step, or in a step event function.
