java - Open project with several subprojects in intellij

Question

I have a project with the following structure

dtu-exam-project/
        ├── README.md
        ├── build_and_run.sh
        ├── docker-compose.yml
        ├── dtu-pay-account
        ├── dtu-pay-client
        ├── dtu-pay-log-api
        ├── dtu-pay-rest-api
        ├── dtu-payment-api
        ├── simple-dtu-pay-client
        └── simple-dtu-pay-server

All the folders in dtu-exam-projects/ are their own independent java projects.

I would like to open a new project in intellij with dtu-exam-projects/ as the root so that I can navigate to all the other projects within the same winodw. Therefore I click "open project", then naviagte to dtu-exam-projects/ and click on that. However, when the project has loaded then simple-dtu-pay-client is for some reason the root, and I can't navigate to the other projects.

Why does this happen?

Answer 1

IDE will try to open existing project defined in .idea directory. It may contain unexpected modules and content roots configuration.

Deleting this directory will force IDE to initialize the project from scratch when you try to open the root directory next time.

Another option is to open the Project Structure dialog and configured the modules and content roots manually.
