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. Use Maven exclusions: Another way to solve circular dependency issues is to use Maven exclusions to remove unnecessary dependencies. You can specify the dependencies that you want to exclude from your module in the pom.xml file. For...
