And I am at a loss for how to fix this issue. I tried cleaning and rebuilding, even re-importing. I looked at similar questions like thisbut nothing seems to work.

我不知道如何解决这个问题。我尝试清理和重建，甚至重新导入。我看着像类似的问题这但似乎没有任何工作。

The only way I got the program to run was by changing the parent pom to version 1.3.1.RELEASEBut I do not want to use this version and want to use 1.4.1.RELEASE

我让程序运行的唯一方法是将父 pom 更改为 version1.3.1.RELEASE但是我不想使用这个版本并且想使用1.4.1.RELEASE

Any help would be greatly appreciated.

任何帮助将不胜感激。

回答by Jay

You need to find log4j and add in your classpath.

您需要找到 log4j 并添加到您的类路径中。

Answer 2

回答by Marcelo Ferreira

See that message: (you manage dependency duplicate, for dependency transitive, that cause dependency duplicate with differents versions)

请参阅该消息：（您管理依赖项重复，对于依赖传递，导致不同版本的依赖项重复）

Class path contains multiple SLF4J bindings. SLF4J: Found binding in

类路径包含多个 SLF4J 绑定。SLF4J：发现绑定

make a test if use IDE Eclipse

测试是否使用 IDE Eclipse

short cut key: Shift+Ctrl+T

快捷键：Shift+ Ctrl+T

that way you see what file has contains this class:

这样你就可以看到包含这个类的文件：

SLF4J: Found binding in [jar:file:
/C:/Users/Josh/.m2/repository/ch/qos/logback/logback-classic/1.1.7/logback-classic-1.1.7.jar!

/org/slf4j/impl/StaticLoggerBinder.class]

repeat class in

复课

slf4j-log4j12-1.7.21.jar
logback-classic-1.1.7.jar

find your same dependency and exclusion what don't you need in your project

找到您的项目中不需要的相同依赖项和排除项

that way:

那样：

<dependency>
<groupId>org.seleniumhq.selenium</groupId>
<artifactId>selenium-java</artifactId>
<version>3.0.0-beta2</version>
<scope>test</scope>
<exclusions>
    <exclusion>
        <artifactId>xml-apis</artifactId>
        <groupId>xml-apis</groupId>
    </exclusion>
</exclusions>

that one example, change for your context

Below actions worked for me

以下操作对我有用

Run mvn dependency:purge-local-repositoryto remove all dependencies and force a re-download.
Then do a mvn clean verify

运行mvn dependency:purge-local-repository以删除所有依赖项并强制重新下载。
然后做一个 mvn clean verify

Answer 4

回答by amir110

I add this dependency and problem resolved.

我添加了此依赖项并解决了问题。

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
</dependency>

you just use version of logback-classic if thiserror occurred.

如果发生此错误，您只需使用 logback-classic 版本。

回答by InvincibleCoder

The issue does not exists with version 1.3.5. I changed my version to

版本 1.3.5 不存在此问题。我把我的版本改成

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.3.5.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

It works !!

有用！！

回答by bourne

It may be a version problem, I change my version of springboot from 2.0.0.RELEASE to 1.5.4.RELEASE, the exception disappeared.

可能是版本问题，我把springboot的版本从2.0.0.RELEASE改成1.5.4.RELEASE，异常消失了。

<parent>

We can skip logging dependency and it will work for us.

我们可以跳过日志依赖，它对我们有用。
