英文:
Why IntelliJ is showing Dependency 'org.slf4j:slf4j-simple:1.7.25' not found?
问题
我已经从mvn仓库添加了slf4j的依赖。
在添加了该依赖后，我的pom.xml如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<groupId>org.example</groupId>
<artifactId>KafkaProject</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<!-- https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients -->
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>2.6.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.25</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
在将这个依赖添加到我的项目后，出现了以下错误：
依赖 'org.slf4j:slf4j-simple:1.7.25' 未找到
顺便说一下，我正在使用 IntelliJ IDEA。那么，如何解决这个问题？
英文:
I have added slf4j dependency from mvn repository.
My pom.xml is given below after adding that dependency :
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<groupId>org.example</groupId>
<artifactId>KafkaProject</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<!-- https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients -->
<dependency>
<groupId>org.apache.kafka</groupId>
<artifactId>kafka-clients</artifactId>
<version>2.6.0</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.25</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
After adding this dependency in my project, it is giving an error saying that:
Dependency 'org.slf4j:slf4j-simple:1.7.25' not found
By the way, I am using IntelliJ IDEA. So, how to resolve this issue ?

这不会给我错误。
我认为依赖项没有下载是因为网络太慢。
尝试通过执行 Maven Update/Install 来更新项目，以重新下载依赖项。
尝试使用这个 pom.xml：
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>KafkaProject</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>simple Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.25</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<finalName>KafkaProject</finalName>
</build>
</project>
英文:
It's not giving me the error.
I think the dependencies are not downloaded due to slow network.
Try to update the project by doing Maven Update/Install to download the dependencies again.
Try this pom.xml :
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>org.example</groupId>
<artifactId>KafkaProject</artifactId>
<packaging>war</packaging>
<version>0.0.1-SNAPSHOT</version>
<name>simple Maven Webapp</name>
<url>http://maven.apache.org</url>
<dependencies>
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-simple -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.7.25</version>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<finalName>KafkaProject</finalName>
