补充一下...这是 JDK1.8 和 Maven 3.3.9。

尝试添加以下依赖项，其中包括 logback-classic
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.7</version>
</dependency>
它包含在
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.3</version>
</dependency>
将你的记录器初始化为你 class :-
private static final Logger logger = LoggerFactory.getLogger(DemoClass.class)
最后，我将maven-plugin和gatling项目分离出来，并从其他依赖中排除了slfj。
我在 Play Framework 中遇到了类似的问题：
我唯一要做的就是将 Provided 添加到依赖项中。
这是我的案例 SBT:
libraryDependencies += "org.slf4j" % "slf4j-simple" % "1.7.26" % Provided,
我的标准错误有：
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/wf/.m2/repository/org/slf4j/slf4j-simple/1.7.21/slf4j-simple-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/wf/.m2/repository/ch/qos/logback/logback-classic/1.1.5/logback-classic-1.1.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]
指向 http://www.slf4j.org/codes.html#multiple_bindings，它建议将排除项添加到不需要的绑定中。所以我做了一个
mvn dependency:tree | grep -B1 -C1 logback
显示例如
[INFO] +- nl.vaneijndhoven.dukes:rc-watchdog:jar:0.0.2:compile
[INFO] \- ch.qos.logback:logback-classic:jar:1.1.5:compile
[INFO] +- ch.qos.logback:logback-core:jar:1.1.5:compile
[INFO] \- org.slf4j:slf4j-api:jar:1.7.16:compile
虽然有更新版本的 logback-classic：
https://mvnrepository.com/artifact/ch.qos.logback/logback-classic/1.2.3
在我的 eclipse 工作区的 pomfiles 中的版本号 1.7.25 和 1.7.21 之后，我发现我直接使用 vert.x 作为依赖项目（用于调试目的）。当我从构建路径中删除该项目时，我很好。
所以一般的方法是查看你的依赖关系
mvn dependency:tree
并将 slf4j 从冲突的依赖项中排除或将它们一起删除。

尝试添加以下依赖项，其中包括 logback-classic
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-api</artifactId>
<version>1.7.7</version>
</dependency>
它包含在
<dependency>
<groupId>ch.qos.logback</groupId>
<artifactId>logback-classic</artifactId>
<version>1.1.3</version>
</dependency>
将你的记录器初始化为你 class :-
private static final Logger logger = LoggerFactory.getLogger(DemoClass.class)
最后，我将maven-plugin和gatling项目分离出来，并从其他依赖中排除了slfj。
我在 Play Framework 中遇到了类似的问题：
我唯一要做的就是将 Provided 添加到依赖项中。
这是我的案例 SBT:
libraryDependencies += "org.slf4j" % "slf4j-simple" % "1.7.26" % Provided,
我的标准错误有：
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/wf/.m2/repository/org/slf4j/slf4j-simple/1.7.21/slf4j-simple-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/wf/.m2/repository/ch/qos/logback/logback-classic/1.1.5/logback-classic-1.1.5.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.SimpleLoggerFactory]
指向 http://www.slf4j.org/codes.html#multiple_bindings，它建议将排除项添加到不需要的绑定中。所以我做了一个
mvn dependency:tree | grep -B1 -C1 logback
显示例如
[INFO] +- nl.vaneijndhoven.dukes:rc-watchdog:jar:0.0.2:compile
[INFO] \- ch.qos.logback:logback-classic:jar:1.1.5:compile
[INFO] +- ch.qos.logback:logback-core:jar:1.1.5:compile
[INFO] \- org.slf4j:slf4j-api:jar:1.7.16:compile
虽然有更新版本的 logback-classic：
https://mvnrepository.com/artifact/ch.qos.logback/logback-classic/1.2.3
在我的 eclipse 工作区的 pomfiles 中的版本号 1.7.25 和 1.7.21 之后，我发现我直接使用 vert.x 作为依赖项目（用于调试目的）。当我从构建路径中删除该项目时，我很好。
所以一般的方法是查看你的依赖关系
mvn dependency:tree
并将 slf4j 从冲突的依赖项中排除或将它们一起删除。
