问题描述

I have an enum ProductID ,我有一个枚举ProductID ，

import org.apache.commons.lang3.StringUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public enum ProductID {

.....

}

with corresponding test有相应的测试

public class ProductIDTest {

    @Test
    public void test1(){
        --
    }
    
    @Test
    public void test2(){
        --
    }

    @Test
    public void test3(){
        --
    }

}

While using green run button from intelliJ, it is passing,在使用来自 intelliJ 的绿色运行按钮时，它正在通过，

在此处输入图像描述

but while I am running it using mvn test , this is failing with following error但是当我使用mvn test运行它时，它失败并出现以下错误

I added below in my pom.xml我在下面添加了我的 pom.xml

<exclusion>
    <groupId>org.slf4j</groupId>
    <artifactId>log4j-over-slf4j</artifactId>
</exclusion>

I was earlier excluding this from incorrect dependency.我早些时候将其排除在不正确的依赖项之外。 I used mvn dependency:tree to determine appropriate dependency it was coming from.我使用mvn dependency:tree来确定它来自的适当依赖项。
