unable to write the logs to log file using log4j through Gradle

I am working on Cucumber TestNg Gradle automation project. As I am new to Gradle and not able to figure the issue though I have put in appropriate log4j dependencies in build.gradle file. Can somebody look into this issue and provide the solutions or advise me on what went wrong due to which logs are not written to log file called "ApplicationLogs.log"

Below is my project structure

Below is my Log4j.properties file contents

Root logger option

    log4j.rootLogger=INFO, RFILE,STDOUT
# Console Appender
log4j.appender.name=STDOUT
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender
log4j.appender.STDOUT.Target=System.out
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout 
log4j.appender.STDOUT.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%-5p] [%c{1}] - [%M] %m%n
# Rolling File Appender
log4j.appender.name=RFILE
log4j.appender.RFILE=org.apache.log4j.RollingFileAppender
log4j.appender.RFILE.File=./Automation_Report/logs/ApplicationLogs.log
log4j.appender.RFILE.threshold=INFO
log4j.appender.RFILE.maxFileSize=25MB
log4j.appender.RFILE.maxBackupIndex=100
log4j.appender.RFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.RFILE.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%-5p] [%c{1}] - [%M] %m%n

I found the issue.

The problem was that you didn't use the LoggerHelper.

This is my project structure :

Updated LoggerHelper class :

To test whether LoggerHelper is working or not. I added one Test class with main method :

Console :

The log generated file.

After doing lot of analysis and comparing i found the solution to my question. The solution is very simple only mistake that i need to remove the unwanted plugins used due to which it created all of issues.

When I removed the application plugin as shown below in plugin section it started working properly and even logs started working.

plugins {
id 'java'
id 'maven-publish'
id 'java-library'
id 'java-gradle-plugin'
}
