I try to load configuration from an external file on a fat jar.

I tried to load configuration from multiples methods without success.

I kept two methods on my sample:

{code:java}
if (!Files.isReadable(log4jConfiguration)) {
    throw new IllegalStateException();
}

LOGGER.info("startup");
LOGGER.debug("startup"); // Not logged = OK

// First try to load configuration
Configurator.initialize(null, log4jConfiguration.toString());
LOGGER.debug("with init"); // Should be logged

// Second try to load configuration
// From log4j FAQ : https://logging.apache.org/log4j/2.x/faq.html#reconfig_from_code
final LoggerContext context = (LoggerContext) LogManager.getContext(false);
context.setConfigLocation(log4jConfiguration.toUri());

LOGGER.debug("reconfig from code"); // Should be logged
LOGGER.info("shutdown"); // Should be logged with [OUTER] prefix
{code}
 

The code works when running from IDE, but when executed with {{java -jar}} the external configuration is not loaded.

Result when running from IDE:  !image-2020-02-06-21-20-15-004.png!

Result when running from jar: !image-2020-02-06-21-21-14-488.png!

I expect to have the configuration file loaded when running my jar file like when running from IDE.
