micronaut-guides-infrastructure

name: micronaut-guides-infrastructure description: Use when modifying the Micronaut Guides build infrastructure, including buildSrc guide generators, macro substitutions, metadata parsing/schema, categories, generated Gradle tasks, guide features, dependency coordinate replacement, indexing, feeds, theme processing, and the cli module.

Micronaut Guides Infrastructure

Scope

Use this skill for changes outside normal guide content, especially:

• buildSrc/src/main/groovy/io/micronaut/guides/**
• buildSrc/src/main/java/io/micronaut/guides/**
• buildSrc/src/main/resources/guide-metadata.schema.json
• buildSrc/src/main/resources/pom.xml
• root build.gradle, settings.gradle, and gradle/asciidoc.gradle
• cli/**
• generated guide task behavior, macros, feed/index output, and feature registration

For ordinary guide content under guides/, use micronaut-guides-authoring first.

Key Files

• GuideAsciidocGenerator.groovy: custom Asciidoc macros, placeholders, exclusions, and rendered .adoc generation.
• GuidesPlugin.groovy: dynamic Gradle tasks such as <slug>Build, <slug>GenerateDocs, <slug>RunTestScript, and zip generation.
• GuideProjectGenerator.groovy and core/DefaultGuideProjectGenerator.java: generated sample project assembly.
• GuideParser.java, Guide.java, App.java, and guide-metadata.schema.json: metadata contract.
• Category.java: ordered display categories.
• core/*MacroSubstitution.java: reusable macro implementations used by tests.
• feature/*.java: local Starter feature replacements or additions.
• buildSrc/src/main/resources/pom.xml: dependency coordinates used by local features and replacement logic.
• IndexGenerator.groovy, JsonFeedGenerator, RssFeedGenerator, and ThemeProcessor.groovy: published site metadata and presentation.

Change Pattern

1. Find an existing test for the affected behavior under buildSrc/src/test.
2. Add or update a focused test before changing generator behavior when possible.
3. Keep macro syntax backward-compatible unless the user explicitly asks for a breaking migration.
4. Update guide-metadata.schema.json and metadata parsing together when adding metadata fields.
5. Update Category.java only with display strings that should appear on the public guide site.
6. For new local features, add the feature class and ensure dependency coordinates exist in buildSrc/src/main/resources/pom.xml when needed.

Validation

Run focused buildSrc tests for infrastructure changes:

./gradlew buildSrc:test --tests '<test-class-or-pattern>' --stacktrace

If tests touch Gradle task wiring or generated guide output, also build at least one representative guide:

./gradlew <lowerCamelSlug>Build --stacktrace

For broad generator or schema changes, run:

./gradlew buildSrc:test --stacktrace
./gradlew build --stacktrace

Use the micronaut-guides-validation skill for guide-specific rendering and generated sample project checks.

Review Risks

Before finishing, check for:

• Silent changes to all guides caused by macro, placeholder, or template edits.
• Metadata schema drift from parser behavior or tests.
• Task name changes that break documented commands or CI.
• Dependency replacement changes that affect both Gradle and Maven generated projects.
• Generated files or build artifacts accidentally staged outside intended outputs.
