I created OR Mapping from persistence window as per https://www.jetbrains.com/help/idea/generate-persistence-mapping-import-dialogs.html. It generated entities and single mapping.xml file. When generating the mapping, I had to add some relationships as they do not exist as foreign key constraint in database. After everything is done, I realized that I made a small mistake. Now that I want to correct that, I cannot find any way to load the generated mapping.xml file to see existing mappings in order to correct them. It seems that I need to start from scratch. Is there any way out?
