Calling a task for each file in a set of files with a simple ant with the file name as a parameter (without tabs, without own tasks)

Problem:

If you have files that match a specific naming convention (e.g. locale) and need to be processed based on each file using an ant script, what are the options in ant?

Example:

Files for processing:

  • file_en-US.txt
  • file_en-GB.txt
  • ...

The task should be called for all files with their file name as a parameter. The locale contained in the file name must be extracted by the regular expression and passed to the external tool as a parameter. The selection will be direct as soon as you have the file name.

Limitations:

  • Ant (1.7), custom/contrib, foreach. Ant (1.7).
