Upgrade slf4j-api to 2.0

seratch commented 2 years ago

slf4j project released a new major version - 2.0.

According to the migration guide, ~~it's safe to upgrade the dependency in this project but it requires a minor version bump of this SDK.~~ EDIT: I might be wrong. Perhaps, if we release a new version with slf4j-api 2.0 dependency, real-world apps such as Spring Boot web apps would be suffered from behavior changes. We should hold off upgrading to 2.0 for the time being.

Another factor we should consider for this upgrade is that logback-classic 1.4 and perhaps other implementations of sfl4j-api v2 no longer supports Java 1.8. Yes, the version is long-lived old version but this SDK still supports the version for broader audience.
