187ADOBE FLEX 3
Building and Deploying Adobe Flex 3 Applications
The following options are implemented as implicit FileSets:
compiler.external-library-path
compiler.include-libraries
compiler.library-path
compiler.theme
compiler.include-sources (compc only)
The Flex Ant task's implicit FileSets are also different from the Ant project's implicit FileSets in that they support
being empty, as in the following example:
<external-library-path/>
This is equivalent to using external-library-path= on the command line.
Using the mxmlc task
You use the mxmlc Flex Ant task to compile applications, modules, resource modules, and Cascading Style Sheets
(CSS) SWF files. This task supports most mxmlc command-line compiler options, including aliases.
For more information on using the mxmlc command-line compiler, see “Using mxmlc, the application compiler”
on page 139.
Required attributes
The mxmlc task requires the file attribute. The file attribute specifies the MXML file to compile. This attribute
does not have a command-line equivalent because it is the default option on the command line.
Unsupported options
The following mxmlc command-line compiler options are not supported by the mxmlc task:
• help
• version
Example
The following example mxmlc task explicitly defines the source-path and library-path options, in addition to
other properties such as
incremental and keep-generated-actionscript. This example also specifies an
output location for the resulting SWF file. This example defines two targets: main and clean. The main target
compiles the Main.mxml file into a SWF file. The clean target deletes the output of the main target.
