Kawa with Android Studio and Gradle

[Marius Kjeldahl <marius at kjeldahl dot net>]

As you may know, Google has released a tech preview of Android Studio,
their fork of the IntelliJ Java IDE (replacing Eclipse) and gradle for
building (replacing ant).

I've been trying to get a simple program running as a first step of
contributing some kawa build scripts, but I have hit a road block.
Basically, I'm trying to compile and run the example found here:

http://www.gnu.org/software/kawa/Android-view-construction.html

I've basically created a new "blank" project in Android Studio, gotten
rid of the generated java stuff and replaced it with my own class files
compiled (manually for now) from the scheme source file.

When the gradle build script tries to package my application however, it
fails while running dx, and considering I haven't done much inside kawa
yet, it's somewhat cryptic to me. I'm sharing it here hoping to get some
hints if this is something related to kawa/java interrop has been
implemented in kawa, or any other hints on how to proceed.

I've attached the output I get after running "./gradlew assembleDebug".

Considering the classes it refers to and my brief recollection about
some of the tricks being used by kawa, I figured somebody here might
have a much better clue than me of what needs to be done.

Thanks,

Marius Kjeldahl

The TaskContainer.add() method has been deprecated and is scheduled to
be removed in Gradle 2.0. Please use the create() method instead.
