logging frameworks 31 (e.g. java.util.logging, logback, log4j) allowing the end user to 32 plug in the desired logging framework at <em>deployment</em> 33 time. </p> 34 35 <p>Before you start using SLF4J, we highly recommend that you read 36 the two-page <a href="manual.html">SLF4J user manual</a>. 37 </p> 38 39 <p>Note that SLF4J-enabling your library implies the addition of 40 only a single mandatory dependency, namely <em>slf4j-api.jar</em>. 41 If no binding is found on the class path, then SLF4J will default to 42 a no-operation implementation. 43 </p> 44 45 <p>In case you wish to migrate your Java source files to SLF4J, 46 consider our <a href="migrator.html">migrator tool</a> which can 47 migrate your project to use the SLF4J API in just a few minutes.</p> 48 49 <p>In case an externally-maintained component you depend on uses a 50 logging API other than SLF4J, such as commons logging, log4j or 51 java.util.logging, have a look at SLF4J's binary-support for <a 52 href="legacy.html">legacy APIs</a>. 53 </p> 54 55 <h3>Projects depending on SLF4J</h3> 56 57 <p>Here is a non-exhaustive list of projects known to depend on 58 SLF4J, in alphabetical order: 59 </p> 60
