不确定我错过了什么。任何人都可以分享如何纠正错误。

此致

Answer 1

我有同样的错误，我相信我的解决方案解决了它。我正在使用Maven，所以我在POM文件中添加了一个依赖项，而不是将.jar文件显式添加到构建路径中。

这里是依赖项（最新版本列在下面链接的顶部。在我的情况下，它是1.7.24，所以如果你可以替换＃34; $ {的最新版本SLF4J版本}＆＃34;：

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-api</artifactId>
        <version>${slf4j-version}</version>
    </dependency>

这是https://mvnrepository.com/artifact/org.slf4j/slf4j-api

如果有效，请告诉我。
