The `HDF5_ENABLE_THREADSAFE` option is still available to build with thread-safe API calls. +- Enhanced Maven repository deployment support + + Added comprehensive Maven integration with optimized workflows for Java artifact deployment: + - **New CMake options**: `HDF5_ENABLE_MAVEN_DEPLOY` and `HDF5_MAVEN_SNAPSHOT` for Maven repository deployment + - **Minimal build presets**: Added `ci-MinShar-*-Maven*` presets for efficient Java-only artifact generation + - **Multi-platform support**: Automated generation of platform-specific JARs with classifiers (linux-x86_64, windows-x86_64, macos-x86_64, macos-aarch64) + - **CI/CD integration**: Enhanced GitHub Actions workflows (`maven-staging.yml`, `maven-deploy.yml`) with cross-platform build matrix + - **Artifact validation**: Comprehensive validation framework for Maven artifacts before deployment + - **Deployment targets**: Support for GitHub Packages and Maven Central staging repositories + - Reorganized the files in the config/cmake folder into the config folder structure The config folder CMake files have been reorganized to make it easier to maintain and add new features.

**Updated Maven Deployment Workflow** (`.github/workflows/maven-deploy.yml`) + +#### **Enhanced Artifact Detection** +- **Before**: Only found `jarhdf5-*.jar` files (main library only) +- **After**: Finds both `jarhdf5-*.jar` and `hdf5-java-examples-*.jar` files +- **Impact**: Supports deployment of both HDF5 Java library and examples artifacts + +```bash +# Updated artifact detection logic +platform_jars=$(find "$platform_dir" \( -name "jarhdf5-*.jar" -o -name "hdf5-java-examples-*.jar" \) 2>/dev/null || true) +``` + +#### **Dynamic Artifact Type Detection** +- **Feature**: Automatically detects artifact type and applies appropriate settings +- **HDF5 Java Library**: Uses platform-specific classifiers (linux-x86_64, windows-x86_64, etc.) +- **Java Examples**: No classifier (platform-independent) + +```bash +if [[ "${jar_basename}" == *"hdf5-java-examples"* ]]; then + ARTIFACT_ID="hdf5-java-examples" + # No classifier for examples +else + ARTIFACT_ID="hdf5-java" + # Platform-specific classifier +fi +``` + +#### **Enhanced Release Notes** +- **Updated**: Release notes template now shows both artifacts +- **Includes**: Maven and Gradle dependency examples for both products +- **Details**: Platform support information + +### 2. **Enabled Live Deployment** (`.github/workflows/release.yml`) + +#### **Key Change** +```yaml +# Before +dry_run: true # Start with dry run to test permissions + +# After +dry_run: false # Enable live deployment to HDFGroup packages +``` + +#### **Configuration Status** +- ✅ **Repository URL**: `https://maven.pkg.github.com/HDFGroup/hdf5` (already configured) +- ✅ **Repository ID**: `github` (already configured) +- ✅ **Authentication**: `github.actor` + `secrets.GITHUB_TOKEN` (already configured) +- ✅ **Permissions**: `packages: write` (already configured) + +### 3. **Created Dedicated Test Workflow** (`.github/workflows/test-maven-deployment.yml`) + +#### **Purpose** +- Isolated testing of Maven deployment functionality +- Permission validation without affecting main release workflow +- Support for both dry-run and live deployment testing + +#### **Features** +- **Repository Permission Checks**: Validates GitHub Packages access +- **API Testing**: Tests GitHub Packages API connectivity +- **Test Artifact Generation**: Creates minimal test artifacts for validation +- **Deployment Testing**: Calls main deployment workflow with test artifacts +- **Result Validation**: Checks GitHub Packages for deployed artifacts + +#### **Usage Examples** +```bash +# Test permissions without deploying +gh workflow run test-maven-deployment.yml -f test_mode=dry-run + +# Test actual deployment with minimal artifacts +gh workflow run test-maven-deployment.yml -f test_mode=live-deployment +``` + +### 4. **Created Consumer Test Script** (`.github/scripts/test-maven-consumer.sh`) + +#### **Purpose** +- Validates deployed artifacts from end-user perspective +- Tests Maven dependency resolution and compilation +- Provides comprehensive validation framework + +#### **Features** +- **Automatic Test Project Creation**: Generates test Maven project +- **Dependency Resolution Testing**: Validates artifact availability +- **Compilation Testing**: Ensures artifacts work correctly +- **Cleanup**: Automatic cleanup of test artifacts + +#### **Usage** +```bash +# Test specific version and repository +./.github/scripts/test-maven-consumer.sh 2.0.0-3 https://maven.pkg.github.com/HDFGroup/hdf5 + +# Test with defaults +./.github/scripts/test-maven-consumer.sh +``` + +### 5. **Updated Documentation** (`CLAUDE.md`) + +#### **Enhanced Testing Commands** +- Added dedicated Maven deployment testing commands +- Included consumer validation testing +- Updated with HDFGroup packages URLs +- Provided step-by-step testing workflow + +## Deployment Architecture + +### **Artifacts to be Deployed** + +#### **HDF5 Java Library** (`org.hdfgroup:hdf5-java`) +```xml + + org.hdfgroup + hdf5-java + 2.0.0-3 + linux-x86_64 + +``` + +**Platform Variants:** +- `linux-x86_64` +- `windows-x86_64` +- `macos-x86_64` +- `macos-aarch64` + +#### **HDF5 Java Examples** (`org.hdfgroup:hdf5-java-examples`) +```xml + + org.hdfgroup + hdf5-java-examples + 2.0.0-3 + + +``` + +**Content**: 62 Java examples across 4 categories (H5D, H5T, H5G, TUTR) + +### **Repository Configuration** + +#### **Target Repository** +- **URL**: `https://maven.pkg.github.com/HDFGroup/hdf5` +- **Type**: GitHub Packages +- **Visibility**: Public (accessible without authentication for consumption) + +#### **Authentication** +- **Username**: `github.actor` (automatic) +- **Token**: `secrets.GITHUB_TOKEN` (automatic) +- **Permissions**: `packages: write` (configured in workflows) + +## Testing Strategy + +### **Phase 1: Permission Validation** +```bash +# Test repository access and permissions +gh workflow run test-maven-deployment.yml -f test_mode=dry-run +``` + +**Validates:** +- GitHub Packages API access +- Repository write permissions +- Workflow configuration correctness + +### **Phase 2: Deployment Testing** +```bash +# Test actual deployment with minimal artifacts +gh workflow run test-maven-deployment.yml -f test_mode=live-deployment +``` + +**Validates:** +- Artifact upload functionality +-

Native Library Distribution Strategy ✅ - -**Decision**: Platform-specific JARs with classifiers - -**Implementation**: -- `hdf5-java-{version}-linux-x86_64.jar` -- `hdf5-java-{version}-windows-x86_64.jar` -- `hdf5-java-{version}-macos-x86_64.jar` -- `hdf5-java-{version}-macos-aarch64.jar` - -**Benefits**: Better dependency management, smaller downloads, explicit platform targeting - -### 2. Artifact Availability in CI ✅ - -**Decision**: Use `ctest.yml` workflow with `ci-StdShar` preset as artifact source - -**Implementation**: -- Maven deployment workflow will download artifacts from `ctest.yml` runs -- Artifacts include both JAR files and platform-specific native libraries -- Ensure artifact naming consistency between build and deployment workflows - -### 3. Version Handling for Snapshots ✅ - -**Decision**: Use `-SNAPSHOT` suffix for development builds - -**Implementation**: -- Release versions: Use HDF5 version directly (`2.0.0-2`) -- Development builds: Append `-SNAPSHOT` (`2.0.0-3-SNAPSHOT`) -- Workflow logic will detect and handle snapshot versions appropriately - -### 4. Maven Central Migration Timeline ✅ - -**Decision**: Target Maven Central after initial GitHub Packages implementation and testing - -**Timeline**: -- Phase 1: GitHub Packages MVP (immediate priority) -- Phase 2: Maven Central preparation (after successful Phase 1 deployment) -- Requires OSSRH account setup, GPG signing infrastructure, staging repository workflow - -### 5. Backward Compatibility ✅ - -**Decision**: Maintain existing JAR distribution while adding Maven deployment - -**Implementation**: -- CPack-generated installers continue to include JARs -- No changes to existing JAR installation paths -- Maven deployment is additive, not replacement -- Users can choose between traditional installers or Maven dependency management - -## Approved Implementation Enhancements - -### 1. Enhanced Error Handling and Validation ✅ - -**Implementation**: -```yaml - pre-deployment-validation: - runs-on: ubuntu-latest - steps: - - name: Validate Java artifacts exist - run: | - if [[ ! -f "jarhdf5-*.jar" ]]; then - echo "ERROR: Main JAR artifact not found" - exit 1 - fi - - name: Validate POM completeness - run: | - xmllint --noout pom.xml || { echo "Invalid POM"; exit 1; } - - name: Validate version consistency - run: | - JAR_VERSION=$(echo jarhdf5-*.jar | sed 's/jarhdf5-\(.*\)\.jar/\1/') - POM_VERSION=$(xmllint --xpath "//version/text()" pom.xml) - [[ "$JAR_VERSION" == "$POM_VERSION" ]] || { echo "Version mismatch"; exit 1; } -``` - -### 2. Staging Repository for Release Validation ✅ - -**Implementation**: -- Add staging deployment for PR builds -- Use GitHub Packages staging area for validation -- Manual promotion step for production releases -- Automated cleanup of failed staging deployments - -### 3.
