# GacTaskBase

[This is preliminary documentation and subject to change.]

Base class functionality for the GAC tasks.

Concrete GAC tasks extend this class in order to obtain common functionality.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
force | bool | Gets or sets a value indicating whether the GAC operation will be forced. | 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 | Deprecated. Specifies whether the external program is a managed application which should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <reference>

Specifies reference details to use when working with the GAC.

Used to specify reference information when working with the GAC.

The full details of GAC references can be found in the SDK documentation.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
if | bool | If `true` then the entity will be included. The default is `true`. | False
scheme-description | string | The scheme description to use when working with GAC references. This is only relevant if a scheme type other than `None` is specified. | False
scheme-id | string | The scheme ID to use when working with GAC references. This is only relevant if a scheme type other than `None` is specified. | False
scheme-type | SchemeType | The scheme type to use when working with GAC references. The default is `None`, which means that references will not be used by the GAC task. | False
unless | bool | Opposite of `if`. If `false` then the entity will be included. The default is `false`. | False

#### </reference>

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

When passed to an external application, the argument will be quoted when appropriate. This does not apply to the `line` parameter, which is always passed as is.

### Parameters

Attribute | Type | Description | Required
--- | --- | --- | ---
dir | directory | The value for a directory-based command-line argument; will be replaced with the absolute path of the directory. | False
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>

### Requirements

Assembly: NAnt.Contrib.Tasks (0.93.5002.0)
