You can find the Wikipedia data dumps here. Each language version has it’s own subdirectory, e.g. for English this is here.

Download Tool for Revision Dumps

The Wikipedia revision is split into many files. Downloading them manually can be cumbersome.

You can find a download tool for Wikipedia dumps here.

It can be used for bulk downloads all dump files for any language. It also supports resuming aborted downloads.

(You don’t need the tool to download the three dump files for JWPL Core. It only makes sense for the revision dumps.)
