Add support for conf/ folder configuration location by afalhambra-hivemq · Pull Request #178 · hivemq/hivemq-azure-cluster-discovery-extension

afalhambra-hivemq · 2026-01-30T12:37:46Z

Summary

Add support for placing azDiscovery.properties as config.properties in the conf/ subfolder of the extension home directory
Legacy location (extension root folder) still supported with a deprecation warning

Changes

Added ConfigResolver class to resolve configuration file location with legacy fallback
Updated ConfigReader to use ConfigResolver with CONFIG_PATH and LEGACY_CONFIG_PATH
Moved azDiscovery.properties to conf/config.properties subfolder in the extension ZIP
Added logback as implementation dependency for unit tests
Updated README to reference new config location
Updated all test references from STORAGE_FILE to LEGACY_CONFIG_PATH

Behavior

Scenario	Result
Config only in `conf/`	Uses new location, no warning
Config only in root (legacy)	Uses legacy location, logs WARN once
Config in both locations	Uses legacy location, logs WARN once
No config file	Extension logs warning (unchanged behavior)

Testing

Added ConfigResolverTest with 5 test cases covering all resolution scenarios
Added conf/ folder configuration test to ConfigReaderTest
Updated AzureDiscoveryExtensionIT to use new conf/ path
All unit tests pass

Support both legacy (azDiscovery.properties) and new (conf/config.properties) configuration paths based on extension version. Versions >= 1.2.8 use the new path, while earlier versions use the legacy path.
