maven spring-boot dependencies Java

I've encountered a strange issue with I'm working through a tutorial and I can't seem to get I'm working with a frustrating scenario with my multi-module Spring Boot project while using Maven. I've structured my project with three modules: `core`, `service`, and `web`. The `service` module depends on `core`, and the `web` module depends on both `service` and `core`. When I try to run `mvn clean install`, I get the following behavior: ``` [behavior] Failed to execute goal on project web: Could not resolve dependencies for project com.example:web:jar:1.0-SNAPSHOT: Failure to find com.example:core:jar:1.0-SNAPSHOT in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1] ``` I've tried cleaning the Maven cache with `mvn clean`, and I also attempted to use the `-U` flag for forcing updates, but the same behavior continues. My `pom.xml` files for each module are as follows: **core/pom.xml**: ```xml <project ...> <groupId>com.example</groupId> <artifactId>core</artifactId> <version>1.0-SNAPSHOT</version> </project> ``` **service/pom.xml**: ```xml <project ...> <parent> <groupId>com.example</groupId> <artifactId>parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <artifactId>service</artifactId> <dependencies> <dependency> <groupId>com.example</groupId> <artifactId>core</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> </project> ``` **web/pom.xml**: ```xml <project ...> <parent> <groupId>com.example</groupId> <artifactId>parent</artifactId> <version>1.0-SNAPSHOT</version> </parent> <artifactId>web</artifactId> <dependencies> <dependency> <groupId>com.example</groupId> <artifactId>service</artifactId> <version>1.0-SNAPSHOT</version> </dependency> <dependency> <groupId>com.example</groupId> <artifactId>core</artifactId> <version>1.0-SNAPSHOT</version> </dependency> </dependencies> </project> ``` I suspect there might be an scenario with how the modules are set up or how dependencies are resolved. Is there a best practice for handling cyclic dependencies in Maven that I might be missing? Any insights would be greatly appreciated! Is there a better approach? Cheers for any assistance! This is part of a larger REST API I'm building. I'm open to any suggestions. Thanks for any help you can provide!
