Module dependencies are empty

I use IntelliJ IDEA 2024.2 (Ultimate Edition), and I am building a multi-module maven project.  The maven build works in the sense that all of the dependencies are downloaded and the war file is constructed. But if I try to use Dependency Analyzer, the list of resolved dependencies is empty.  In the project settings, the module dependencies are not listed.  I have tried everything that I can think of to get this working again (as it has worked correctly in the past), but nothing helps.  I have tried invalidating caches and restarting, I have used an external maven installation instead of the built-in.  I have re-imported the project multiple times, sometimes after deleting the .idea folder. Any suggestions for me?
