Sets a property if a certain condition holds true - this is a +generalization of Available and Uptodate.
+If the condition holds true, the property value is set to true by
+default; otherwise, the property is not set. You can set the value to
+something other than the default by specifying the value
+attribute.
Conditions are specified as nested elements, +you must specify exactly one condition.
+| Attribute | +Description | +Required | +
| property | +The name of the property to set. | +Yes | +
| value | +The value to set the property to. Defaults to + "true". | +No | +
All conditions to test are specified as nested elements.
+ +The <not> element expects exactly one other
+condition to be nested into this element, negating the result of the
+condition. It doesn't have any attributes and accepts all nested
+elements of the condition task as nested elements as well.
+The <and> element doesn't have any attributes and
+accepts an arbitrary number of conditions as nested elements - all
+nested elements of the condition task are supported. This condition
+is true if all of its contained conditions are, conditions will be
+evaluated in the order they have been specified in the build file.
The <and> condition has the same shortcut
+semantics as the Java && operator, as soon as one of the
+nested conditions is false, no other condition will be evaluated.
+The <or> element doesn't have any attributes and
+accepts an arbitrary number of conditions as nested elements - all
+nested elements of the condition task are supported. This condition
+is true if at least one of its contained conditions is, conditions
+will be evaluated in the order they have been specified in the build
+file.
The <or> condition has the same
+shortcut semantics as the Java || operator, as soon as one of the
+nested conditions is true, no other condition will be evaluated.
This condition is identical to the Available task, all attributes and nested +elements of that task are supported, the property and value attributes +are redundant and will be ignored.
+ +This condition is identical to the Uptodate task, all attributes and nested +elements of that task are supported, the property and value attributes +are redundant and will be ignored.
+ +Test whether the current operating system is of a given type.
+| Attribute | +Description | +Required | +
| family | +The name of the operating system family to expect. | +No | +
Supported values for the family attribute are: +
Tests whether the two given Strings are identical
+| Attribute | +Description | +Required | +
| arg1 | +First string to test. | +Yes | +
| arg2 | +Second string to test. | +Yes | +
+ <condition property="javamail.complete"> + <and> + <available classname="javax.activation.DataHandler" /> + <available classname="javax.mail.Transport" /> + </and> + </condition> ++
sets the property javamail.complete if both the
+JavaBeans Activation Framework and JavaMail are available in the
+classpath.
+ <condition property="isMacOsButNotMacOsX"> + <and> + <os family="mac" /> + <not> + <os family="unix" /> + </not> + </and> + </condition> ++
sets the property isMacOsButNotMacOsX if the current
+operating system is MacOS, but not MacOS X - which Ant considers to be
+in the Unix family as well.
