The Simple Logging Facade for Java (SLF4J) serves as a simple facade or abstraction for various logging frameworks (e.g. java.util.logging, logback, reload4j, log4j 2.x) allowing the end user to plug in the desired logging framework at deployment time.
More information can be found on the SLF4J website.

In case of problems
In case of problems please do not hesitate to post an e-mail message on the email@example.com mailing list. However, please do not directly e-mail SLF4J developers. The answer to your question might be useful to other users. Moreover, there are many knowledgeable users on the slf4j-user mailing lists who can quickly answer your questions.
For urgent issues do not hesitate to champion a release. In principle, most championed issues are solved within 3 business days ensued by a release.
How to build SLF4J
SLF4J uses Maven as its build tool.
SLF4J version 2.0.x will run under Java 8 but requires Java 9 or later to build.
How to contribute pull requests
If you are interested in improving SLF4J, that is great! The SLF4J community looks forward to your contribution. Please follow this process:
Fork qos-ch/slf4j. Ideally, create a new branch from your fork for your contribution to make it easier to merge your changes back.
Make your changes on the branch you hopefully created in Step 2. Be sure that your code passes existing unit tests. Please add unit tests for your work if appropriate. It usually is.
Push your changes to your fork/branch in GitHub. Don't push it to your master! If you do it will make it harder to submit new changes later.
Submit a pull request to SLF4J from your commit page on GitHub.
Did we mention that you will be asked to link your pull request with a Jira ticket?
