Is there something akin to

ArchiveOperations.zipTree

but for creating zip files? I know there is the

Zip

task but that can't be used inside an artifact transform.

Afair no, you have to use normal means like a

ZipOutputStream

there's an Ant Zip task which may be easier. but using that is not typed. I would use java.util.zip.ZipOutputStream (as mentioned) or org.apache.commons.compress.archivers.zip.ZipArchiveOutputStream (better support for Zip64)

The Ant ZIP task might be an option, but not really convenient, as it is inside an artifact transform and the ant builder is still not injectable anywhere.

Yeah the point of the question is if there's something as convenient as the Zip task. Maybe we'll get an API like that some day
