OSGi Workshop - Build Pipeline Assignment

Assignment

Your task is to create a smart build pipeline for the Northwind Order Management System that can build the product in two different scenarios:

Scenario 1: Build All Products

Build all modules in the correct dependency order.

Scenario 2: Build Only Changed Products/Modules

Detect which modules have been modified, identify all dependent modules that need to be rebuilt, and build only those modules in the correct dependency order with visibility into the build order.

---

Note: These modules are interdependent. Changes in one module may require rebuilding other modules that depend on it.

---

How to Test Your Solution

1. Modify files from 3+ different modules randomly across different functional domains
2. Run your build pipeline with the "changed modules only" scenario
3. Check the build logs to verify:
   • Which modules were detected as changed
   • The complete dependency chain resolution
   • The order in which modules were built
   • Confirmation that only necessary modules were rebuilt

Example Test Case

Modify source files in:

• catalog/plugins/com.northwind.oms.core/src/...
• orders/plugins/com.northwind.oms.gateway/src/...
• payment/plugins/com.northwind.oms.payment/src/...

Your pipeline should detect these changes, identify all dependent modules, and build them in the correct order with clear logging.

Deliverable

Part 1:

A working build pipeline (Maven configuration, build script, or custom tool) that supports both build scenarios with clear, verbose logging showing:

• Detected changes
• Module dependency chain
• Build order and sequence

Part 2:

The pipeline must also display the product dependency graph. The graph must show:

• The dependency graph for both the full-build and changed-modules scenarios
• All product modules and their dependencies
• The direction of each dependency
• The dependency path for every changed module
• The modules selected for rebuilding in the changed-modules scenario
