Hi, as I have been pointed to in chat by Vincent, it is possible to place ApplicationResources*.properties files containing translation keys in the src/main/resources directory of any maven "jar"-packaged project and get them used as translations, instead of adding keys to the xwiki-platform-oldcore/src/main/resources/ApplicationResources*.properties This is already documented as a "best practice" for application development: http://dev.xwiki.org/xwiki/bin/view/Community/ApplicationDevelopmentBestPra… However it is missing for the platform development practices, so I would have missed it if not been pointed to explicitly. If nobody objects, I would like to add a line recommending this at e.g. http://dev.xwiki.org/xwiki/bin/view/Community/DevelopmentPractices#HTransla… Or are there any reasons against this practice / or is there a better one?
