Maven uses a project model to describe dependencies and build configuration. Understand the lifecycle phases and keep declared versions and repositories deliberate.
Before you begin
Be comfortable with variables, conditions, loops and basic methods. Use a small local project with a recorded JDK version and keep the input data fictional.
Work through the idea
Write the expected behavior before implementing the exercise. Keep the first version small enough to trace manually, then change one input or requirement. Record both the successful path and an invalid or empty-input case so that the result demonstrates reasoning rather than a copied output.
- Read the project POM
- Run a clean build and tests
- Inspect a dependency conflict
Practice task
Build a small sample project from a clean directory using its checked-in POM.
Check your result
Explain the difference between compilation, testing and packaging output.
A mistake to avoid
Do not add arbitrary dependencies until an unresolved class error disappears.
Keep a review note
Save the inputs or scenario, your reasoning and the result you checked. Explain one assumption and one case that needs more work. Revise the exercise after feedback and distinguish what you demonstrated from what remains untested.
