java - SLF4J 版本不匹配和重复绑定(bind)

Question

我有一个使用以下 Maven 依赖项的项目:

<dependency>
                <groupId>com.dropbox</groupId>
                <artifactId>client2</artifactId>
                <version>1.3</version>

                <artifactId>guice</artifactId>

            </dependency>
            <dependency>
                <groupId>com.google.code.gson</groupId>
                <artifactId>gson</artifactId>

            </dependency>
            <dependency>

                <version>2.12</version>
            </dependency>
        </dependencies>

当我运行它时，它会发出警告并提示:

SLF4J: The requested version 1.5.10 by your slf4j binding is not compatible with [1.5.5, 1.5.6, 1.5.7, 1.5.8]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

我的理解是有不止一个依赖包含slf4j。我应该可能从他们排除 slf4j。但我不知道我的哪一个依赖项实际上导致了这一点。

有人可以帮忙吗？

问候

Answer 1

尝试运行 mvn dependency:tree -Dincludes=*slf4j*。它应该向您显示哪个 Artifact 定义了对 slf4j 的依赖性。

附加参数可用于过滤特定的 slf4j 依赖项。有关插件和特定依赖项过滤的更多信息，请参阅 here .
