Bart S. commented on LOG4J2-952:
--------------------------------

{quote}Forcing compile time dependency on the log4j-core module would be an 
issue though (if that could be avoided otherwise).{quote}

Indeed you would be requiring any user of the builder to delve deeply into the 
Core. You'd be importing all those core classes. If you want an interface to be 
minimal, you should not be posing such requirements, even if you have an 
automated tool that will fill in the details for you. Anybody who does not use 
that IDE will be fux0red. The whole idea of creating a clean API is that it is 
minimal and easy to use, not sub-par-minimal and only easy to use if the 
required tools are in place.

> {quote}
> You could use the static method #initialize(String contextName, ClassLoader 
> loader, String configLocation) in 
> org.apache.logging.log4j.core.config.Configurator. (You can pass null for the 
> class loader.) Be aware that this class is not part of the public API so your 
> code may break with any minor release.
> {quote}
> This documentation is unclear because it points to a member function which 
> needs a filename {{configLocation}} where as the topic is »without a 
> configuration file«.
> It shoud rather point to the member function 
> {{org.apache.logging.log4j.core.config.Configurator.initialize(ClassLoader 
> loader, ConfigurationSource source)}}.
> Example:
> {code:java}
> import org.apache.logging.log4j.core.config.ConfigurationSource;
> import org.apache.logging.log4j.core.config.Configurator;
> final String hardCodedXmlConfig =
>         "<?xml version='1.0' encoding='UTF-8'?>\n" +
>         "<Configuration status='INFO'>\n" +
>         "  <Appenders>\n" +
>         "    <Console name='Console' target='SYSTEM_OUT'>\n" +
>         "      <PatternLayout pattern='%d{HH:mm:ss.SSS} [%t] %-5level 
> %logger{36} - %msg%n'/>\n" +
>         "    </Console>\n" +
>         "  </Appenders>\n" +
>         "  <Loggers>\n" +
>         "    <Root level='debug'>\n" +
>         "      <AppenderRef ref='Console'/>\n" +
>         "    </Root>\n" +
>         "  </Loggers>\n" +
>         "</Configuration>\n";
> try {
>     Configurator.initialize(null, new ConfigurationSource(new 
> ByteArrayInputStream(hardCodedXmlConfig.getBytes())));
> } catch (IOException e) {
>     e.printStackTrace();
> }
> {code}
