Fix ModelBuilderException

✅ Solution

ModelBuilderException in nx often arises when the workspace graph is inconsistent with the physical project structure or when dependencies are improperly defined, especially in Maven projects. Ensure that your `nx.json` and `project.json` files accurately reflect project dependencies and that `pom.xml` files are correctly structured with proper parent-child relationships declared and reachable within the workspace. Run `nx graph` or `nx dep-graph` to visually inspect the dependency graph and identify inconsistencies; then, correct the relevant configuration files.
