is there a built-in support in Groovy to handle Zip files (the groovy way)?
Or do i have to use Java's java.util.zip.ZipFile to process Zip files in Groovy ?
AFAIK, there isn't a native way. But check out the article Powerful Groovy on how you'd add a .zip(...) method to File, which would be very close to what you're looking for. You'd just need to make an .unzip(...) method.
