public class PropertyTask : Task, IConditional

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

Remarks

NAnt uses a number of predefined properties.

Attributes

Type	Description
TaskNameAttribute	Indicates that class should be treated as a task.

Properties

Name	Value	Summary
CustomXmlProcessing	bool	Gets a value indicating whether the element is performing additional processing using the `NAnt.Core.Element.XmlNode` that was used to initialize the element. Inherited from Element
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.
FailOnError	bool	Determines if task failure stops the build, or is just reported. The default is `true`. Inherited from Task
IfDefined	bool	If `true` then the task will be executed; otherwise, skipped. The default is `true`. Inherited from Task
Location	Location	Gets or sets the location in the build file where the element is defined. Inherited from Element
LogPrefix	string	The prefix used when sending messages to the log. Inherited from Task
Name	string	The name of the task. Inherited from Task
NamespaceManager	XmlNamespaceManager	Gets or sets the `System.Xml.XmlNamespaceManager`. Inherited from Element
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`.
Parent	Object	Gets or sets the parent of the element. Inherited from Element
Project	Project	Gets or sets the `NAnt.Core.Element.Project` to which this element belongs. Inherited from Element
Properties	PropertyDictionary	Gets the properties local to this `NAnt.Core.Element` and the `NAnt.Core.Element.Project`. Inherited from Element
PropertyName	string	The name of the NAnt property to set.
ReadOnly	bool	Specifies whether the property is read-only or not. The default is `false`.
Threshold	Level	Gets or sets the log threshold for this `NAnt.Core.Task`. By default the threshold of a task is `NAnt.Core.Level.Debug`, causing no messages to be filtered in the task itself. Inherited from Task
UnlessDefined	bool	Opposite of `NAnt.Core.Task.IfDefined`. If `false` then the task will be executed; otherwise, skipped. The default is `false`. Inherited from Task
Value	string	The value to assign to the NAnt property.
Verbose	bool	Determines whether the task should report detailed build log messages. The default is `false`. Inherited from Task
XmlNode	XmlNode	Gets or sets the XML node of the element. Inherited from Element

Methods

Name	Value	Summary
CopyTo(Element)	void	Copies all instance data of the `NAnt.Core.Element` to a given `NAnt.Core.Element`. Inherited from Element
Execute()	void	Executes the task unless it is skipped. Inherited from Task
ExecuteTask()	void	Executes the task.
GetAttributeConfigurationNode(FrameworkInfo, string)	XmlNode	Locates the XML node for the specified attribute in either the configuration section of the extension assembly or the.project. Inherited from Task
GetAttributeConfigurationNode(XmlNode, FrameworkInfo, string)	XmlNode	Inherited from Element
GetLocation()	Location	Retrieves the location in the build file where the element is defined. Inherited from Element
Initialize()	void	Initializes the task. Inherited from Task
Initialize(XmlNode)	void	Performs default initialization. Inherited from Element
InitializeBuildElement(Element, XmlNode, Element, Type)	Element	Initializes the build element. Inherited from Element static
InitializeElement(XmlNode)	void	Derived classes should override to this method to provide extra initialization and validation not covered by the base class. Inherited from Element
InitializeTask(XmlNode)	void	Initializes the task. Inherited from Task
InitializeTaskConfiguration()	void	Initializes the configuration of the task using configuration settings retrieved from the NAnt configuration file. Inherited from Task
InitializeXml(XmlNode, PropertyDictionary, FrameworkInfo)	void	Initializes all build attributes and child elements. Inherited from Element
IsLogEnabledFor(Level)	bool	Determines whether build output is enabled for the given `NAnt.Core.Level`. Inherited from Task
Log(Level, string)	void	Logs a message with the given priority. Inherited from Task
Log(Level, string, Object[])	void	Logs a formatted message with the given priority. Inherited from Task
