Adobe® Flex® Builder™ automatically builds and exports your projects into applications, creating application and library files, placing the output files in the proper location, and alerting you to any errors encountered during compilation.
There are several options for modifying the build settings to control how your projects are built into applications. For example, you can set build preferences on individual projects or on all the projects in your workspace, modify the build output path, change the build order, and so on. You can also create custom build instructions using third-party build tools such as the Apache Ant utility.
When your applications are ready to be released, you have the option of publishing all or selected parts of the application source code. Users can view your application source code in a web browser, similar to the way they are able to view HTML source code.
