The article outlines the integration of Java projects into an Nx monorepo using the @nx/gradle plugin, facilitating a seamless collaboration between Java backends and JavaScript frontends. It describes setting up a simple Java backend with Spring Boot that offers various REST endpoints and demonstrates how to integrate it with an existing Nx workspace housing a React frontend. By employing the nx import command, developers can migrate the Java backend into the Nx workspace, allowing for coordinated execution of frontend and backend processes using Nx commands. The piece emphasizes the ease of managing these processes together, particularly through the use of the dependsOn configuration in the package.json file for the React app, which ensures that both Java and JavaScript projects can run simultaneously. Additionally, it highlights how developers can leverage Gradle's continuous build feature to automatically apply changes to the backend, thereby streamlining the development workflow. This approach is presented as an advantageous solution for polyglot environments, where teams can benefit from the expansive features of Nx while working with a mix of programming languages.
