# <ccupdate>

Updates a ClearCase view.

This task uses the `cleartool update` command to update a ClearCase view.

### Parameters

Attribute | Type | Description | Required

currenttime | bool | Specifies that modification time should be written as the current time. Only one of `currenttime` or `preservetime` can be specified. The default is false. | False
graphical | bool | Displays a graphical dialog during the update. The default is false. | False
log | file | Specifies a log file for ClearCase to write to. | False
overwrite | bool | If true, hijacked files will be overwritten. The default is false. | False
preservetime | bool | Specifies that modification time should preserved from the VOB time. Only one of `currenttime` or `preservetime` can be specified. The default is false. | False
rename | bool | If true, hijacked files will be renamed with a .keep extension. The default is false. | False
viewpath | file | Path to the ClearCase view file or directory that the command will operate on. | 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
--- | --- | --- | ---
exename | string | The name of the executable that should be used to launch the external program. | False
useruntimeengine | bool | Specifies whether the external program should be executed using a runtime engine, if configured. The default is false. | False

### Nested Elements:

#### <arg>

The command-line arguments for the external program.

Represents a command-line argument.

### 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>

### Examples

- Performs a ClearCase update on the snapshot view directory `c:/views/viewdir`. A graphical dialog will be displayed. The output will be logged to `log.log` and it will overwrite any hijacked files. The modified time will be set to the current time.

      <ccupdate viewpath="c:/views/viewdir"
              graphical="false"
              log="log.log"
              overwrite="true"
              currenttime="true"
              rename="false"/>
