Can I add extra soure folder?

[Makoto Yamazaki]

Hi,

Is there any way to add extra source folder to each Build Variant in build.gradle?

I'd like to use Pluggable Annotation Processing API (JSR 269).

I wrote build.gradle to use PAP as follows, but I couldn't find the way to add 

"${project.buildDir}/source/apt_generated/${variant.dirName}" as

an extra source folder.

android.applicationVariants.each { variant ->

    def aptOutput = file("${project.buildDir}/source/apt_generated/${variant.dirName}")

    variant.javaCompile.doFirst {

        aptOutput.mkdirs()

        aptOutput.eachFileRecurse groovy.io.FileType.FILES, {

            it.delete()

        }

        variant.javaCompile.options.compilerArgs += [

                '-processorpath', "<path of factory jar>",

                '-s', aptOutput

        ]

    }

}

I found two ugly workarounds.

First, I used "${project.buildDir}/source/r/${variant.dirName}" instead of 

"${project.buildDir}/source/apt_generated/${variant.dirName}".

Second workaround, I took over 'sourceOutputDir' of Renderscript.

tasks["compile${variant.name}Renderscript"].sourceOutputDir = aptOutput

It worked, and it's too ugly...

These two workarounds completely work with Build Variant switching in Android Studio,

but I'd like to avoid these ugly way...

any suggestions?

There's no easy way to do this now, it's all going to be ugly.
