111-java-maven-dependencies

Use when you need to add or evaluate Maven dependencies that improve code quality — including nullness annotations (JSpecify), static analysis (Error Prone + NullAway), functional programming (VAVR), or architecture testing (ArchUnit) — and want a consultative, question-driven approach that adds only what you actually need. Part of the skills-for-java project

Add Maven dependencies for improved code quality

Add essential Maven dependencies that enhance code quality and safety through a consultative, question-driven approach. This is an interactive SKILL.

What is covered in this Skill?

  • JSpecify: (nullness annotations, provided scope)
  • Error Prone + NullAway: (enhanced static analysis with compile-time null checking)
  • VAVR: (functional programming with Try/Either and immutable collections)
  • ArchUnit: (architecture rule enforcement, test scope)

Constraints

Before adding Maven dependencies, ensure the project is in a valid state. Use a consultative, question-driven flow that adds only what the user selects.

  • MANDATORY: Run ./mvnw validate or mvn validate before any changes
  • SAFETY: If validation fails, stop and ask the user to fix issues—do not proceed until resolved
  • BEFORE ASKING QUESTIONS: Read the reference to use the exact wording and options from the template. Ask questions one-by-one in strict order (JSpecify → Enhanced Compiler Analysis (conditional) → VAVR → ArchUnit) and add only what the user selects. Use consultative language, present trade-offs, and wait for user responses before implementing

When to use this skill

  • Add Maven dependencies
  • Add JSpecify nullness dependencies
  • Add Error Prone NullAway dependencies
  • Add VAVR functional dependencies
  • Add ArchUnit architecture testing dependencies
