Configuration Log4j2 introuvable lors de l'exécution d'une application autonome créée par le plug-in shade

J'ai une application qui fonctionne lorsque je lance à partir de maven log4j2:

mvn exec:Java -Dexec.args=...

mais quand je lance jar en tant qu'application autonome, alors il affiche une erreur:

Java -jar

bûche:

Je ne comprends pas cette erreur. Il montre que le fichier de configuration log4j2 n’est pas trouvé, mais se plaint également d’un format qui se trouve probablement dans le fichier de configuration.

Ma configuration est:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="off">
    <Appenders>
        <Console name="console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d [%t] %-5p - %-26.26c{1} - %m\n" />
        </Console>
    </Appenders>
    <Loggers>
        <Root level="info">
            <AppenderRef ref="console" />
        </Root>

        <Logger name="my.package" level="DEBUG" /> 

    </Loggers>
</Configuration>

et il se trouve dans le répertoire racine du fichier jar.

METTRE À JOUR

jar est créé par le plugin maven shade:

        <groupId>org.Apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>

il contient donc toutes les bibliothèques nécessaires (environ 23 Mo) et quand j’exécute ce jar, j’ai juste besoin de spécifier des arguments 

javalog4j2maven-shade-plugin

ok j'ai trouvé ce problème problème à propos de ce problème.

En bref, le problème se pose lorsque les classes d’application sont emballées dans uber jar à l’aide du plugin maven shade. Alors que pour log4j2 version 2.8.1 le correctif est toujours en attente, la solution suggérée consiste à mettre à jour maven pom.xml avec des paramètres de configuration supplémentaires pour le plug-in shade comme suit: 

    <project xmlns="http://maven.Apache.org/POM/4.0.0"

Veuillez vous référer à cela pour obtenir un exemple complet de pom.file.

En plus de la réponse donnée par @hudi, .__, nous devons ajouter des dépendances à l'intérieur du plug-in pour la transformation.
