I'll take a crack at this. In your application module class (normally AppModule.java), set the Symbol constants.BOOTSTRAP_ROOT symbol to where your replacement bootstrap files are installed (the parent of the bootstrap css and js subfolders). As far as I understand, there are no other changes needed to have Tapestry use your version of Bootstrap. See the "Overriding Bootstrap (Tapestry 5.4 and later)" section of https://tapestry.apache.org/css.html
