ERROR StatusLogger Log4j2 could not find a logging implementation

I am attempting to incorporate log4j 2 but it continues to throw the subsequent error.

> ERROR StatusLogger Log4j2 could not find a logging implementation.
> Please add log4j-core to the classpath. Using SimpleLogger to log to
> the console...

I have attempted the solution provided on the internet. However, they do not appear to be effective for me. Output: I have tried the solution given on the web

This is the program that I am attempting to execute.

package demo;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
public class LogExample {
    private static final Logger LOG = LogManager.getLogger(LogExample.class);
    public static void main(String[] args) {
        LOG.debug("This Will Be Printed On Debug");
        LOG.info("This Will Be Printed On Info");
        LOG.warn("This Will Be Printed On Warn");
        LOG.error("This Will Be Printed On Error");
        LOG.fatal("This Will Be Printed On Fatal");
        LOG.info("Appending string: {}.", "Hello, World");
    }
}

Project and reliance included in the pom.Xml:.

Any assistance is welcomed.

This reliance helps to prevent this mistake from lambda.

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-to-slf4j</artifactId>
    <version>2.8.2</version>

Fixed the error message by configuring the log4j2 configuration file’s system property. Here is the code snippet.

System.setProperty("log4j.configurationFile","./path_to_the_log4j2_config_file/log4j2.xml");
Logger log = LogManager.getLogger(LogExample.class.getName());

If you have already included log4j-core in your maven pom, there is no need for any additional steps as it should function properly. The issue might lie with your IDE not recognizing the maven dependency. Attempting to reload or reimport maven dependencies, or even restarting your IDE, can potentially resolve the problem.

In IntelliJ on Mac, the log4j dependency was not included in the classpath for some unknown reason. Therefore, what I did was.

After including the following in the pom.Xml file.

        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-api</artifactId>
            <version>2.20.0</version>
        </dependency>
        <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-core</artifactId>
            <version>2.20.0</version>
        </dependency>

I manually obtained the log4j compressed file from https://www.Apache.Org/d

And after extracting the file I included log4j-core and log4j-api to the project directory as shown below.

To work around a comparable problem with Spring Boot I included.Output: To resolve a similar issue

In my situation, the mistake was connected to the maven-shade-plugin version (3.2.2).

It functions when I configure this plugin to version 3.2.1.

I encountered this issue in NetBeans 8.2 when I included the jar log4j-api-2.12

Netbeans display this message in the console:.

StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console…

I solved this issue by including log4j-core-2.12.2.0001

I assume that in the Spring season, you simply need to include the log4j-core dependency in Maven.

Download the JAR

I was facing the same issue for upgrading log4j from 1.X to Log4j-2.17.1. Was getting this error while deploying to GlassFish server.

I followed these steps to rectify the situation:

Disabled the autoInitialization of Log4j2. Added to web

<context-param> <param-name>isLog4jAutoInitializationDisabled</param-name> <param-value>true</param-value> </context-param>

Initializing Log4j

InputStream inputStream = new FileInputStream(“path of Log4j2.Xml”); ConfigurationSource source = new ConfigurationSource(inputStream); Configurator.Initialize(null

In my situation, if you have included the dependencies in the pom.Xml file, simply navigate to the Project Settings – Modules in your IDE and alter the Scope from Test to Compile. There’s no requirement to download any zip files.

The problem can be solved by simply including log4j-core-2.12

Thanks.
