Apache Log4j 2 Kotlin API

Log4j Kotlin API is a Kotlin logging facade based on Log4j 2. Log4j Kotlin API provides Log4j 2 as its default logging implementation, but this is not strictly required (e.g., this API can also be used with Logback or other Log4j 2 API provider implementations). Idiomatic Kotlin features are provided as an alternative to using the Log4j 2 Java API.

Build Status

Usage

Gradle users can add the following dependencies to their build.gradle file:

TODO

compile "org.apache.logging.log4j:log4j-api-kotlin:1.2.0"
compile "org.apache.logging.log4j:log4j-api:2.17.0"
compile "org.apache.logging.log4j:log4j-core:2.17.0"

Documentation

Requirements

Log4j Kotlin API requires at least Java 8. This also requires Log4j 2 API, but it is specified as transitive dependencies automatically if you are using SBT, Maven, Gradle, or some other similar build system. This also requires Log4j 2 Core (or possibly an other implementation of Log4j 2 API) as a runtime dependency. Some Log4j 2 Core features require optional dependencies which are documented in the Log4j 2 manual.

The Kotlin API requires the full kotlin-reflect dependency in order to name loggers appropriately, and optionally kotlinx-coroutines-core to set the mapped diagnostic context for a coroutine.

The Kotlin dependencies are not exposed transitively -- for maximum compatibility logging-log4j-kotlin is built with Kotlin 1.3, producing binaries that should be forward compatible. For maximum compat, the Kotlin dependencies are “provided” i.e. consumers of this library need to depend on them directly rather than transitively, thus avoiding version clashes.
