Efficient Code Generation with Telosys for Multi-Module Maven Projects

Managing a multi-module Maven project can be complex, particularly when it comes to generating Java classes across various submodules. Developers often face issues, such as incorrect package declarations during code generation with tools like Telosys. If you've encountered package resolution problems or wish to streamline your code generation process across several modules, you're not alone. This guide will provide you with a comprehensive guide to effectively use Telosys in your Maven multi-module setup.

Understanding the Problem

This typically occurs because the $SRC variable points to src/main/java relative to the parent project, not the specific module where you want the class to be generated. Hence, when attempting to generate classes across different submodules, explicit guidance for Telosys is required to point to the right paths.

Solution Overview

To resolve these issues and streamline code generation in a multi-module Maven project, follow these steps:

Step 1: Define Global Variables in Telosys Configuration

It's beneficial to keep standard variable values for paths like source and resource folders apart from the module-specific configurations.

Step 2: Configure Templates in Each Module

Utilizing these configurations, you can efficiently direct output to each module's designated location.

Step 3: Define Java Package Structure in Templates

To ensure proper Java package declarations during the code generation process, you have two effective methods in your .vm template files:

Utilizing Root Package Variable: Alternatively, declare your Java package structure using the global root package variable.

If you need to specify different parts of the package dynamically, consider using additional global variables.

Conclusion

By following this structured approach, you can simplify the process of generating Java classes across different modules in your Maven project using Telosys. With the right configurations and template setups, you can eliminate the tedious task of manual corrections post-generation and ensure your code is generated in the correct locations seamlessly.

Remember, effective use of global variables, along with proper template configurations, can significantly enhance your workflow and the overall organization of your project structure. Happy coding!
