Soy neófito para Spring Boot y quería cambiar mi registrador predeterminado a log4j2, ya que tiene una tasa de rendimiento más alta que el inicio de sesión.

Aquí está mi script de Gradle. Como puede ver, estoy usando Spring Boot 2.0.3, y para deshabilitar el registrador predeterminado utilicé el módulo de exclusión (logback y spring boot starter logger) después de Spring Boot Web. Estoy compilando log4j en la parte inferior de mi script.

buildscript {
    ext {
        springBootVersion = '2.0.3.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}



apply plugin: 'java'
apply plugin: 'war'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'app'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8



repositories {
    mavenCentral()
    jcenter()
}


ext {
    vaadinVersion = '8.4.1'
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-rest')
    providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.springframework.boot:spring-boot-starter-thymeleaf')

    }
    compile('org.springframework.boot:spring-boot-starter-webflux')

}

dependencyManagement {
    imports {
        mavenBom "com.vaadin:vaadin-bom:${vaadinVersion}"
    }
}

Esta es mi aplicación Spring Boot.

package app.clothapp;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ClothappApplication {

    public static void main(String[] args) {
        SpringApplication.run(ClothappApplication.class, args);
    }
}

Sin embargo, cuando ejecuto mi aplicación Spring Boot, me proporciona un AbstractMethodError. He leído algunas otras preguntas SO, y aparentemente alguna clase ha cambiado inapropiadamente desde la última vez que se compiló. ¿Alguien podría proporcionar alguna ayuda?

Exception in thread "main" java.lang.AbstractMethodError: org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(Lorg/apache/logging/log4j/core/config/ConfigurationSource;)Lorg/apache/logging/log4j/core/config/Configuration;
