Respondiendo a mi propia pregunta después de unas horas de piratería ...
<script language="groovy" src="build.groovy" />
y esta secuencia de comandos groovy reemplaza cualquier archivo javascript o css referenciado con el contenido del archivo en sí.
f = new File("${targetDir}/index.cfm")
fContent = f.text
fContent = jsReplace(fContent)
fContent = cssReplace(fContent)
f.write(fContent)
// JS Replacement
def jsReplace(htmlFileText) {
println "Groovy: Replacing Javascript includes"
// extract all matched javascript src links
def jsRegex = /<script [^>]*src=\"([^\"]+)\"><\/script>/
def matcher = (htmlFileText =~ jsRegex)
for (i in matcher) {
// read external files in
def includeText = new File(matcher.group(1)).text
// sanitize the string for being regex replace string (dollar signs like jQuery/Prototype will screw it up)
includeText = java.util.regex.Matcher.quoteReplacement(includeText)
// weak compression (might as well)
includeText = includeText.replaceAll(/\/\/.*/, "") // remove single-line comments (like this!)
includeText = includeText.replaceAll(/[\n\r\f\s]+/, " ") // replace all whitespace with single space
// return content with embedded file
htmlFileText = htmlFileText.replaceFirst('<script [^>]*src="'+ matcher.group(1) +'"[^>]*></script>', '<script type="text/javascript">'+ includeText+'</script>');
}
return htmlFileText;
}
// CSS Replacement
def cssReplace(htmlFileText) {
println "Groovy: Replacing CSS includes"
// extract all matched CSS style href links
def cssRegex = /<link [^>]*href=\"([^\"]+)\"[^>]*>(<\/link>)?/
def matcher = (htmlFileText =~ cssRegex)
for (i in matcher) {
// read external files in
def includeText = new File(matcher.group(1)).text
// compress CSS
includeText = includeText.replaceAll(/[\n\r\t\f\s]+/, " ")
// sanitize the string for being regex replace string (dollar signs like jQuery/Prototype will screw it up)
includeText = java.util.regex.Matcher.quoteReplacement(includeText)
// return content with embedded file
htmlFileText = htmlFileText.replaceFirst('<link [^>]*href="'+ matcher.group(1) +'"[^>]*>(<\\/link>)?', '<style type=\"text/css\">'+ includeText+'</style>');
}
return htmlFileText;
}
Así que supongo que eso lo hace por mí. Ha funcionado bastante bien, y es extensible. Definitivamente no es el mejor Groovy, pero es uno de los primeros. Además, requirió algunos tarros de clase para compilar. Perdí la noción de cuál, pero creo que es el motor javax.scripting, groovy-engine.jar y groovy-all-1.5.6.jar
