ExternalProgramBase |
v0.90 |
Provides the abstract base class for tasks that execute external applications.
When a ProgramLocationAttribute is applied to the deriving class and exename does not return an absolute path, then the program to execute will first be searched for in the location specified by LocationType.
If the program does not exist in that location, then the list of tool paths of the current target framework will be scanned in the order in which they are defined in the NAnt configuration file.
| Attribute | Type | Description | Required |
|---|---|---|---|
| timeout | int | The maximum amount of time the application is allowed to execute, expressed in milliseconds. Defaults to no time-out. | 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 |
| 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 |
| Attribute | Type | Description | Required |
|---|---|---|---|
| exename | string | The name of the executable that should be used to launch the external program. | False |
| managed | ManagedExecution | Specifies whether the external program should be treated as a managed application, possibly forcing it to be executed under the currently targeted version of the CLR. | False |
| 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 |
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.
| 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 |
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" />
