多个SLF4J绑定intellij linux

Question

我正在尝试运行gradle从IntelliJ IDEA生成的战争。

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/usr/share/java/slf4j-jcl-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/share/java/slf4j-jdk14-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/usr/share/java/slf4j-simple-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]

Answer 1

这里有两种解决方案：

• 确保在类路径中只包含一个slf4j依赖项。
• 如果您的项目依赖于其他项目，而其他项目也使用slf4j，并且版本不同，请尝试使用Excustion

<exclusions>
   <exclusion>
       <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
    </exclusion>
</exclusions>
