Circular Dependency Warning in IntelliJ with Maven in a Java Web Project

Image
Circular Dependency Warning in IntelliJ with Maven in a Java Web Project : When working with a Java web project using Maven, you may encounter a circular dependency warning in IntelliJ. This can happen when a module depends on another module that also depends on the first module, creating a loop. The warning indicates that adding a new dependency may create a circular dependency and lead to a build failure. To solve this issue, you can try several solutions :  Split your project into smaller modules with clear responsibilities. This can help you identify and manage dependencies more effectively. For example, you can move the HrRestApiConnectionException class to a separate module and then include that module as a dependency in the modules that need it.

Copilot Blank Chat in IntelliJ? Create the Missing Files to Fix It

The fast fix (what worked for me) Recreate the exact folder path shown in the error. Create the missing file (an empty Java class with minimal valid code is fine). (For example, in my case I created the Java file and added a valid class with minimal content inside it.) If you don't write a valid class, you will get another error, so make sure to add at least the basic structure inside the file. Restart IntelliJ (Ctrl+Alt+Y or File → Invalidate Caches / Restart). (In my cas...
