Logging with slf4j works in idea but no on command line.

So running vertx 3.4.1

Here is my build. gradle...

plugins {
  id 'java'
  id 'application'
  id 'com.github.johnrengelman.shadow' version '1.2.3'
}

repositories {
  jcenter()
  maven {
    url "https://oss.sonatype.org/content/repositories/snapshots/"
  }
}

sourceCompatibility = '1.8'

dependencies {
  compile 'io.vertx:vertx-core:3.4.1'
  compile 'io.vertx:vertx-web:3.4.1'

  compile 'org.slf4j:slf4j-api:1.7.25'
  compile 'org.apache.logging.log4j:log4j-core:2.8.1'
  compile 'org.apache.logging.log4j:log4j-slf4j-impl:2.8.1'

  compile 'org.hibernate:hibernate-validator:5.4.1.Final'
  compile 'org.glassfish:javax.el:3.0.1-b08'
  compile ('cz.jirutka.validator:validator-collection:2.1.6') {
    exclude module: 'hibernate-validator'
  }

  compile 'org.apache.solr:solr-solrj:6.4.2'

  compile 'com.bazaarvoice.jolt:jolt-core:0.1.0'
  compile 'com.bazaarvoice.jolt:json-utils:0.1.0'
}

mainClassName = 'io.vertx.core.Launcher'

shadowJar {
  classifier = 'fat'

  manifest {
    attributes 'Main-Verticle': 'com.xxx.Main'
  }

  mergeServiceFiles {
    include 'META-INF/services/io.vertx.core.spi.VerticleFactory'
  }
}

Running...

java -Xmx4g -Xmx4g -jar search-api-fat.jar -Dvertx.logger-delegate-factory-class-name=io.vertx.core.logging.SLF4JLogDelegateFactory -Dlog4j.configurationFile=src/main/conf/loj4j2.xml

Any log from vertx logger doesn't consider the log4j2.xml file. Only 3rd parties like Netty, Hibernate etc... So If I change for instance the pattern layout all 3rd parties will use it except anything coming from vertx logger.

Is it something maybe with the fat jar that is generated?

Ok i think I'm a puts lol It helps if the system properties are before the -jar lol
