About SLF4J

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, logevents, penna, rainbowgum, tinylog)
allowing the end user to plug in the desired logging framework at
deployment time.

More information can be found on the SLF4J website.

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:

  1. Start a discussion on the slf4j-dev mailing
    list     about your proposed
    change. Alternately, file a bug
    report     on github to initiate the
    discussion.

  2. Fork qos-ch/slf4j. Ideally, create a new branch from your fork for
    your contribution to make it easier to merge your changes back.

  3. Make your changes on the branch 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.

  4. All commits must have signed off by the contributor attesting to
    Developer Certificate of Origin
    (DCO)    . Commits without sign off
    will be automatically rejected by the DCO GitHub
    check     application.

  5. 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.

  6. Submit a pull request to SLF4J from your commit page on GitHub.
