Cursor-rules-java 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.

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
