Errors in custom build - error(354) Root bundle indicates bundles that don't exists

[AbdulRaheem1308]

I am upgrading the Dojo 1.13.0 to 1.16.2 in the project. While doing custom build am getting around 60 errors which are similar to the bellow in build report.
Root: digit/nls/dijit-all_ar; missing bundles:
'dijit/_editor/nls/FontChoice', 'dijit/_editor/nls/commands', 'dijit/form/nls/ComboBox', 'dijit/form/nls/validate', 'dijit/nls/common', 'dijit/nls/loading', 'dojo/cldr/nls/currency', 'dojo/cldr/nls/gregorian', 'dojo/cldr/nls/number', 'dojo/nls/colors'.

kindly let me know what is the problem.
