If a translation file is deleted on master and not on the branch on which to update the translations, the translation update script will display an output such as

error: pathspec 'xwiki-platform-core/xwiki-platform-oldcore/src/main/resources/ApplicationResources_en.properties' did not match any file(s) known to git.

And in this case the module were the file is located won't get the new translations.
