Javadoc Best Practices for percussioncms

Use this skill when generating or updating Javadoc comments in the percussioncms project.

Quick Start

1. Check JDK version — Look at pom.xml for <source>/<target>/<release> (likely 21)
2. Use the checklist — See reference/javadoc-checklist.md for per-file guidance
3. Run generation scripts — Use scripts/generate-javadoc-stubs.sh for initial stubs

JDK Version Detection

Version	Comment Style	HTML Allowed	Markdown Allowed
JDK 8	/** ... */	Yes	No
JDK 21	/** ... */	Yes	No
JDK 25+	/** ... */ OR ///	Deprecated	Yes

For percussioncms: JDK 21 — use traditional /** ... */ only.

Key Rules

Structure

/**
 * First sentence is the summary (concise, third person, present tense).
 * 
 * <p>Additional details about behavior, side effects, or constraints.</p>
 *
 * @param paramName description of parameter (including constraints like "may not be null")
 * @return description of return value
 * @throws ExceptionType condition that causes this exception
 * @since 8.0.0
 * @see RelatedClass#method
 */

Common Mistakes

• ❌ @returns → ✅ @return
• ❌ "This method does..." → ✅ "Returns..."
• ❌ Implementation details → ✅ Observable behavior
• ❌ Missing @throws for checked exceptions

Inline Tags

• {@link ClassName#method} — Cross-reference
• {@code expression} — Inline code
• {@literal text} — Escape HTML in JDK 25+

Scripts

• scripts/generate-javadoc-stubs.sh — Bash script to generate stub comments
• scripts/generate-javadoc-stubs.ps1 — PowerShell equivalent

Maven Integration

The maven-javadoc-plugin is configured in ai-shared-develop/pom.xml:

# Generate Javadoc HTML
mvn javadoc:javadoc

# Generate Javadoc JAR
mvn javadoc:jar
