| <p>Log4j 2 is broken up in an API and an implementation (core), where the API |
| provides the interface that applications should code to. |
| Strictly speaking Log4j core is only needed at runtime and not at compile time.</p> |
| <p>However, below we list Log4j core as a compile time dependency |
| to improve the startup time for <a href="manual/plugins.html">custom plugins</a> as it provides an |
| annotation processor that generates a metadata file to cache plugin information as well |
| as the necessary code to compile against to create custom plugins.</p><section> |
