I don't know where this come from since i don't user any logger in my whole projet. If you need more information please feel free to ask.
Here is my pom.xml :
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="" xmlns:xsi="" xsi:schemaLocation=" "> <modelVersion>4.0.0</modelVersion> <groupId>org.example</groupId> <artifactId>TestPoi</artifactId> <version>1.0-SNAPSHOT</version> <properties> <maven.compiler.source>8</maven.compiler.source> <maven.compiler.target>8</maven.compiler.target> </properties> <dependencies> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>5.2.2</version> </dependency> </dependencies>

Add the library log4j-api.jar to the classpath.
To make your project work you have to remove all jars starting with log4j-1.x.
I made the same mistake, because when I downloaded the log4j dependency package, I didn't know which files I needed, so I added all of them. But by doing so, for whatever reason, now log4j 1 is used instead of log4j 2.
