# AbstractSourceControlTask

[This is preliminary documentation and subject to change.]

A base class for creating tasks for executing CVS client commands on a CVS repository.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
commandline | string | Command-line arguments for the program. The command line arguments are used to specify any cvs command options that are not available as attributes. These are appended after the command itself and are additive to whatever attributes are currently specified. | False
destination | directory | Destination directory for the local sandbox. If destination is not specified then the current directory is used. | False
passfile | file | The full path to the cached password file. If not specified then the environment variables are used to try and locate the file. | False
password | string | Deprecated. The password for logging in to the repository. | False
ssh | file | The executable to use for ssh communication. | False
failonerror | bool | Determines if task failure stops the build, or is just reported. The default is true. | False
if | bool | If true then the task will be executed; otherwise, skipped. The default is true. | False
timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | False
unless | bool | Opposite of `if`. If false then the task will be executed; otherwise, skipped. The default is false. | False
verbose | bool | Determines whether the task should report detailed build log messages. The default is false. | False

### Framework-configurable parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
useruntimeengine | bool | Specifies whether the external program should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <fileset>

Used to specify the version control system (VCS) files that are going to be acted on.

#### </fileset>

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
file | file | The name of a file as a single command-line argument; will be replaced with the absolute filename of the file. | False
if | bool | Indicates if the argument should be passed to the external program. If true then the argument will be passed; otherwise, skipped. The default is true. | False
line | string | List of command-line arguments; will be passed to the executable as is. | False
path | <path> | The value for a PATH-like command-line argument; you can use `:` or `;` as path separators and NAnt will convert it to the platform's local conventions, while resolving references to environment variables. | False
unless | bool | Indicates if the argument should not be passed to the external program. If false then the argument will be passed; otherwise, skipped. The default is false. | False
value | string | A single command-line argument; can contain space characters. | False

### Nested Elements:

#### <path>

Sets a single command-line argument and treats it like a PATH - ensures the right separator for the local platform is used.

#### </path>

### Examples

- A single command-line argument containing a space character.

      <arg value="-l -a" />

- Two separate command-line arguments.

      <arg line="-l -a" />

- A single command-line argument with the value `\dir;\dir2;\dir3` on DOS-based systems and `/dir:/dir2:/dir3` on Unix-like systems.

      <arg path="/dir;/dir2:\dir3" />

#### </arg>
