Inside the Microsoft® Build Engine: Using MSBuild and Team Foundation Build

Exec Task Changes

The Exec task has three new properties: CustomErrorRegularExpression, CustomWarningRegularExpression, and IgnoreStandardErrorWarningFormat. These three properties are related to a new ability of the Exec task. It can detect errors and warnings that are output from tools automatically if the messages adhere to a given format. For a full discussion about how this works see the "Exec Task" section in Chapter 7.
