Issue with IntelliJ IDEA Java Module Renaming and Compilation

Problem

While utilizing IntelliJ IDEA to rename a Java module, users may encounter issues where the renamed module appears functional within the IDE but cannot be successfully compiled from the command line using javac.

Cause [Optional]

The underlying issue is linked to the command line compilation process, where the specified module-path directory structure does not correctly align with the module placement caused by IntelliJ IDEA's operational processes. Additionally, misunderstanding the proper usage of the -p flag in javac can contribute to the issue.

Resolution

To resolve this:

1. Ensure that the module-path used in the javac command explicitly reflects the directory containing the compiled module classes. This can be adjusted to accommodate IntelliJ's output directory structure.

2. Change the build steps to avoid inconsistencies:

   Replace the javac commands as follows:

   javac -d modules/out ./serviceProviderInterfaceModule/src/module-info.java ./serviceProviderInterfaceModule/src/zoo/tours/api/*.java
   
   javac -d modules/serviceLocatorModule -p modules/out ./serviceLocatorModule/src/module-info.java ./serviceLocatorModule/src/zoo/tours/reservations/*.java
   

3. Verify that IntelliJ IDEA's build configuration outputs expected compiled module structures into designated directories.

Following this adjusted approach should ensure that the renamed module can be appropriately compiled and referenced by other dependent modules. For further assistance, refer to the detailed resources linked, or feel free to contact JetBrains support.
