CHAPTER 19 ■ AUTOMATED BUILD WITH PHING

Now that I have wrapped up the target element, table 19–2 shows a summary of its attributes.

Table 19–2. The Attributes of the target Element

Attribute Required Description

Name Yes The name of the target

Depends No Targets on which the current depends

If No Execute target only if given property is present

Unless No Execute target only if given property is not present

Description No A short summary of the target’s purpose

When a property is set on the command line, it overrides any and all property declarations within
the build file. There is another condition in which a property value can be overwritten. By default, if a
property is declared twice, the original value will have primacy. You can alter this behavior by setting an
attribute called override in the second property element. Here’s an example:

<?xml version="1.0"?>

<project name="megaquiz"
default="main"
