<msbuild> Task

If a project file is not specified, MSBuild searches the current working directory for a file that has a file extension that ends in "proj" and uses that file.

Parameters

Attribute	Type	Description	Required
noautoresponse	bool	Do not auto-include the MSBuild.rsp file.	False
project	file	The project to build.	False
target	string	Build these targets in this project. Use a semicolon or a comma comma to separate multiple targets.	False
verbosity	VerbosityLevel	Specifies the amount of information to display in the MSBuild log.	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

Nested Elements:

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

Set or override these project-level properties.

Sets a property in the current project.

Note: NAnt uses a number of predefined properties.

Parameters

Attribute	Type	Description	Required
name	string	The name of the NAnt property to set.	True
value	string	The value to assign to the NAnt property. This attribute's properties will not be automatically expanded!	True
dynamic	bool	Specifies whether references to other properties should not be expanded when the value of the property is set, but expanded when the property is actually used. By default, properties will be expanded when set.	False
overwrite	bool	Specifies whether the value of a property should be overwritten if the property already exists (unless the property is read-only). The default is true.	False
readonly	bool	Specifies whether the property is read-only or not. The default is false.	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

Examples

Define a debug property with value true.

<property name="debug" value="true" />

Use the user-defined debug property.

<property name="trace" value="${debug}" />

Define a read-only property. This is just like passing in the param on the command line.
```
<property name="do_not_touch_ME" value="hammer" readonly="true" />
    
```
Define a property, but do not overwrite the value if the property already exists (eg. it was specified on the command line).
```
<project name="property-example">
  <property name="debug" value="true" overwrite="false" />
  <echo message="debug: ${debug}" />
</project>
    
```
Executing this build file with the command line option -D:debug=false, would cause the value specified on the command line to remain unaltered.
```
[echo] debug: false
    
```

</property>

<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" />
    
```
