Simple Logging Facade for Java
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 please do not hesitate to post an e-mail message
on the [email protected] 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.
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.
If you are interested in improving SLF4J, that is great! The SLF4J
community looks forward to your contribution. Please follow this
process:
Start a discussion on the slf4j-dev mailing
list about your proposed
change. Alternately, file a bug
report to initiate the
discussion. Note that we ask pull requests to be linked to a Jira
ticket.
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.
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.
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?
