mxmlc ant Flex task in Groovy

Hi,

lately, there was a need to add a flex compilation feature to the Vine Toolkit build system. In the build scripts we're using Groovy as our extension to Ant scripts so I designed some additional logic to automatically choose source files and compile them in a special manner:

• compile only source files with the Vine Toolkit extensions,
• add locale bundles,
• add dependent source paths,
• add external libraries.

I'm presenting this code because not all options were mapped correctly in ant task def, especially the external library path was pretty troublesome :)

Here is the code snippet:

flexAppPath - path to the flex sources.
flexLocalePath - path to the flex locale bundles.
dependentSourcePath - path to dependent flex sources.
flexLibPath - path to the external swc libraries.

        antBuilder.fileset(id: "flexSourcesList", dir: flexAppPath,
                includes: "**/*.mxml") {
                antBuilder.contains(text: "VineApplication")

        if (new File(flexLibPath).exists()) {
            antBuilder.fileset(id: "flexLibList", dir: flexLibPath,
                    includes: "**/*.swc")

        }


        antBuilder.project.references.flexSourcesList.each {
            println "Compiling " + it.name
            antBuilder.mxmlc(
                    file: it) {
                antBuilder.'use-network'('true')
                antBuilder.'compiler.strict'('true')
                antBuilder.'compiler.context-root'('gridsphere')
                antBuilder.'compiler.services'(applicationBuild.getBuildAptPath() + '/WEB-INF/services-config.xml')
                println "*    Using services-config.xml file from: " + applicationBuild.getBuildAptPath() + '/WEB-INF/services-config.xml'
                println "**   Adding locale source path: " + flexLocalePath + '/{locale}'
                antBuilder.'compiler.source-path'(flexLocalePath + '/{locale}')

                new File(flexLocalePath).listFiles().each {
                    if (!it.name.startsWith(".")) {
                        println "**   Adding locale: " + it.name
                        antBuilder.'compiler.locale'(it.name)
                    }
                }

                antBuilder.'compiler.source-path'('path-element': flexAppPath)
                println "***  Adding dependency from: " + flexAppPath

                usesProjectBuildList.each {
                        String dependentSourcePath = it + 'flex/src'
                        antBuilder.'compiler.source-path'('path-element': dependentSourcePath)
                        println "***  Adding dependency from: " + dependentSourcePath
                
                }
                antBuilder.project.references.flexLibList.each {
                    String libraryPath = it
                    println "**** Adding external library: " + libraryPath
                    antBuilder.'compiler.library-path'('file': libraryPath, 'append': 'true')
                }
            }

I especially like this code for listing files:

new File(flexLocalePath).listFiles().each {
if (!it.name.startsWith(".")) {
println "**   Adding locale: " + it.name
antBuilder.'compiler.locale'(it.name)
}
}

This is the pure power of Groovy especially in conjunction with ant features.

Enjoy :)
