Unzip files in the directory they are in with Ant

Question

This should be simple but I can't find a way to do it. I need to extract any zip files in sub directories of a directory to the same sub directory using Ant. The files are passed to the ant task as a fileset with wildcards e.g. */.zip.

For example, the ant script may have to process the file a/b/c/file.zip which contains file.xml so I would like to use the unzip task to extract the file to a/b/c/file.xml but it is not known in advance what the directory structure will be i.e. it could a/b/c/file.zip or t/u/v/w/x/y/z/file.zip.

The unzip task requires the "dest" directory but I don't know what the full dest directory will be until the script is running. I also considered the mapper but as far as I can see this is just for the extracted files I can't reference the zip file location as part of the mapping.

Any help would be greatly appreciated.

Thanks, Stef

You should be able to do this with the "for" task from the ant-contrib package (over a fileset) and standard "dirname" task in the body of the loop. You will also want to use the ant-contrib "var" task to unset the property set by "dirname" or the next loop iteration will not get the new value.
