copy dropbox

def publishDropboxTask = project.tasks.create("publishDropbox")
android.applicationVariants.all { variant ->
     TODO: made dropbox task work with new variant output API
    variant.outputs.each { output ->
        def publishDropboxVariantTask = project.tasks.create("publishDropbox${variant.name.capitalize()}", Copy)
        publishDropboxVariantTask.from(output.outputFile)
        publishDropboxVariantTask.into(file(PUBLISH_FOLDER))
    
        publishDropboxVariantTask.dependsOn variant.assemble
        publishDropboxTask.dependsOn publishDropboxVariantTask
    }
}

я создал такой таск по твоему совету

variant.outputs.each { output ->

    if (variant.buildType.name == "release") {

        ...

        def taskName = "copyMapping${variant.name.capitalize()}";

        def copyMappingVariantTask = project.tasks.create(taskName, Copy) {
            println "executing copying for ${taskName}"
            from mappingPathSrc
            into mappingPathDst
            dependsOn variant.assemble
        }
    }
}

запускаю assemble для своего флейвора, все билдится, в консоли я вижу даже "executing copying...", но почему-то ничего не копируется (( пути проверил.. в чем может быть проблема? может, на момент копирования маппинг файлы еще не созданы?

def copyProguardMappingTask = project.tasks.create("copyProguardMapping")
android.applicationVariants.all { variant ->
    if(variant.getBuildType().isMinifyEnabled()){
       def copyProguardMappingVariantTask = project.tasks.create("copyProguardMapping${variant.name.capitalize()}", Copy)
       copyProguardMappingVariantTask.from(variant.mappingFile)
       copyProguardMappingVariantTask.into(file(MAPPING_FOLDER))
       copyProguardMappingVariantTask.rename ('mapping.txt', "mapping-${variant.name}.txt")

       copyProguardMappingVariantTask.dependsOn variant.assemble
       copyProguardMappingTask.dependsOn copyProguardMappingVariantTask    
    }
}
