Remko Popma updated LOG4J2-797:
-------------------------------
Fix Version/s: 2.1
Assignee: Remko Popma
[~merzedes] Thanks for the clarification. How about this text:
{quote}
Log4j is broken up in an API and an implementation, where the API provides the
interface that applications should code to. So, strictly speaking the Log4j
implementation is only needed at runtime and not at compile time.
In our recommendations below we list the implementation as a compile time
dependency to improve the startup time for [custom
plugins|http://logging.apache.org/log4j/2.x/manual/plugins.html].
The implementation contains an annotation processor that will scan for custom
plugins during compilation and generate a metadata file that allows Log4j to
quickly find custom plugins at runtime. This processor is run by the Java
compiler, so the implementation is listed as a compile dependency.

Too much detail? Perhaps only add this to the Gradle section instead of at the
top of the page?

> Key: LOG4J2-797
> URL: https://issues.apache.org/jira/browse/LOG4J2-797
> Project: Log4j 2
> Issue Type: Improvement
> Components: Documentation
> Affects Versions: 2.0.2
> Environment: http://logging.apache.org/log4j/2.x/maven-artifacts.html
> Reporter: whaefelinger
> Assignee: Remko Popma
> Priority: Minor
> Fix For: 2.1
>
>
> The documentation (website:
> http://logging.apache.org/log4j/2.x/maven-artifacts.html) lists "log4j-core"
> as compile dependency (Gradle).
> While this at not wrong, it does not hit the idea of api/core separation.
> Thus I suggest to list "log4j-core" as runtime dependency, i.e.
> {code}
> dependencies {
> compile group: 'org.apache.logging.log4j', name: 'log4j-api', version:
> '2.0.2'
> runtime group: 'org.apache.logging.log4j', name: 'log4j-core', version:
> '2.0.2'
> }
> {code}
