Exec Class

Definition

This class defines an "Exec" MSBuild task, which simply invokes the specified process with the specified arguments, waits for it to complete, and then returns True if the process completed successfully, and False if an error occurred.

This API supports the product infrastructure and is not intended to be used directly from your code.

Default constructor.

Properties

Bag

This API supports the product infrastructure and is not intended to be used directly from your code.

Gets the collection of parameters used by the derived task class.

(Inherited from ToolTaskExtension)
BuildEngine

The build engine automatically sets this property to allow tasks to call back into it.

(Inherited from Task)
BuildEngine2

The build engine automatically sets this property to allow tasks to call back into it. This is a convenience property so that task authors inheriting from this class do not have to cast the value from IBuildEngine to IBuildEngine2.

(Inherited from Task)
BuildEngine3

Retrieves the IBuildEngine3 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine4

Retrieves the IBuildEngine4 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine5

Retrieves the IBuildEngine5 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine6

Retrieves the IBuildEngine6 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine7

Retrieves the IBuildEngine7 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine8

Retrieves the IBuildEngine8 version of the build engine interface provided by the host.

(Inherited from Task)
BuildEngine9

Retrieves the IBuildEngine9 version of the build engine interface provided by the host.

(Inherited from Task)
canBeIncremental

ToolTask is not incremental by default. When a derived class overrides SkipTaskExecution, then Question feature can take into effect.

(Inherited from ToolTask)
Command

This API supports the product infrastructure and is not intended to be used directly from your code.

Gets or sets the command to run.

ConsoleOutput

This API supports the product infrastructure and is not intended to be used directly from your code.

Returns the output as an Item. Whitespace are trimmed. ConsoleOutput is enabled when ConsoleToMSBuild is true. This avoids holding lines in memory if they aren't used. ConsoleOutput is a combination of stdout and stderr.

ConsoleToMSBuild

This API supports the product infrastructure and is not intended to be used directly from your code.

Enable the pipe of the standard out to an item (StandardOutput).

CustomErrorRegularExpression

This API supports the product infrastructure and is not intended to be used directly from your code.

Users can supply a regular expression that we should use to spot error lines in the tool output. This is useful for tools that produce unusually formatted output

CustomWarningRegularExpression

This API supports the product infrastructure and is not intended to be used directly from your code.

Users can supply a regular expression that we should use to spot warning lines in the tool output. This is useful for tools that produce unusually formatted output

EchoOff

When set to true, it passes /Q to the cmd.exe command line such that the command line does not get echo-ed on stdout

(Inherited from ToolTask)
EnvironmentOverride
Obsolete.

Gets the Path override value.

(Inherited from ToolTask)
EnvironmentVariables

Array of equals-separated pairs of environment variables that should be passed to the spawned executable, in addition to (or selectively overriding) the regular environment block.

(Inherited from ToolTask)
ExitCode

The return code of the spawned process. If the task logged any errors, but the process had an exit code of 0 (success), this will be set to -1.

(Inherited from ToolTask)
FailIfNotIncremental (Inherited from ToolTask)
HasLoggedErrors

This API supports the product infrastructure and is not intended to be used directly from your code.

Whether this ToolTaskExtension has logged any errors

(Inherited from ToolTaskExtension)
HelpKeywordPrefix

Gets or sets the prefix used to compose help keywords from string resource names. If a task does not have help keywords associated with its messages, it can ignore this property or set it to null. If the prefix is set to an empty string, then string resource names will be used verbatim as help keywords. For an example of how this prefix is used, see the TaskLoggingHelper.LogErrorWithCodeFromResources(string, object[]) method.

(Inherited from Task)
HostObject

The build engine sets this property if the host IDE has associated a host object with this particular task.

(Inherited from Task)
IgnoreExitCode

This API supports the product infrastructure and is not intended to be used directly from your code.

Gets or sets a Boolean value that indicates whether the Exec task should ignore the exit code provided by the executed command (true) or should return false if the executed command returns a non-zero exit code (false).

IgnoreStandardErrorWarningFormat

This API supports the product infrastructure and is not intended to be used directly from your code.

Whether to use pick out lines in the output that match the standard error/warning format, and log them as errors/warnings. Defaults to false.

Methods

AddCommandLineCommands(CommandLineBuilderExtension)

This API supports the product infrastructure and is not intended to be used directly from your code.

Adds the arguments for cmd.exe

AddResponseFileCommands(CommandLineBuilderExtension)

This API supports the product infrastructure and is not intended to be used directly from your code.

AdjustCommandsForOperatingSystem(String)

Replace backslashes with OS-specific path separators, except when likely that the backslash is intentional.

(Inherited from ToolTask)
CallHostObjectToExecute()

We expect the tasks to override this method, if they support host objects. The implementation should call into the host object to perform the real work of the task. For example, for compiler tasks like Csc and Vbc, this method would call Compile() on the host object.

(Inherited from ToolTask)
Cancel()

Cancels the process executing the task by asking it to close nicely, then after a short period, forcing termination.

(Inherited from ToolTask)
DeleteTempFile(String)

Delete temporary file. If the delete fails for some reason (e.g. file locked by anti-virus) then the call will not throw an exception. Instead a warning will be logged, but the build will not fail.
