feat: add GCP Parameter Manager and Secret Manager OpenFeature providers#1
Conversation
Adds two new OpenFeature Java providers backed by GCP-native storage: - `providers/gcp-parameter-manager`: Reads feature flags from Google Cloud Parameter Manager (google-cloud-parametermanager:0.31.0). Supports flag keys mapping directly to parameter names with optional prefix, configurable version (default "latest"), TTL-based in-memory cache (default 5 min, 500 entries), and Application Default Credentials with optional explicit GoogleCredentials. - `providers/gcp-secret-manager`: Reads feature flags from Google Cloud Secret Manager (google-cloud-secretmanager:2.57.0). Identical configuration surface with secretVersion, cacheExpiry, cacheMaxSize, and secretNamePrefix options. Both providers: - Implement all 5 OpenFeature evaluation methods (bool/string/int/double/object) - Parse JSON values into OpenFeature Value/MutableStructure for object flags - Map GCP NotFoundException → FlagNotFoundError, other errors → GeneralError - Pass all quality gates: Checkstyle, PMD, SpotBugs, Spotless - Include 41 unit tests each (FlagCache, FlagValueConverter, provider tests) - Include @tag("integration") tests gated by GCP_PROJECT_ID env var Registers both modules in root pom.xml, release-please-config.json, and .release-please-manifest.json at version 0.0.1. https://claude.ai/code/session_017KfN53GLayq9uci3NXuAn4
…oviders Creates two standalone Maven sample applications under samples/ to demonstrate end-to-end usage of the GCP OpenFeature providers against a real GCP project. samples/gcp-secret-manager-sample/ - SecretManagerSampleApp.java — evaluates 5 flag types (bool/string/int/double/object) using GcpSecretManagerProvider with ADC and a 30s TTL cache - setup.sh / teardown.sh — gcloud commands to create/delete the sample secrets - pom.xml — standalone Maven project with exec-maven-plugin - README.md — step-by-step instructions with expected output and troubleshooting samples/gcp-parameter-manager-sample/ - ParameterManagerSampleApp.java — identical scenario for GcpParameterManagerProvider with locationId="global" and parameterNamePrefix="of-sample-" - setup.sh / teardown.sh — gcloud commands for Parameter Manager API - pom.xml / README.md — same structure as Secret Manager sample Feature flags demonstrated (e-commerce scenario): dark-mode (bool), banner-text (string), max-cart-items (int), discount-rate (double), checkout-config (JSON object) Samples are NOT added to the root multi-module build (no quality gate overhead). Run `mvn install -DskipTests` from repo root first, then `mvn exec:java` in each sample. https://claude.ai/code/session_017KfN53GLayq9uci3NXuAn4
