使用slf4j.marker时，我正在获取java.lang.incompatibleclasschangeerror。似乎我在ClassPath中有几个SLF4J版本。但是，当执行Maven依赖性时：树说只有SLF4J 1.7.25。你们有什么想法可能是什么问题？依赖项如下：
- logback 1.2.3
- SLF4J 1.7.25
- logstash-logback-regoder 5.0
该应用程序部署在Wildflly 8.2.1 AS。

您是正确的，因为ClassPath中的几个SLF4J版本
现在我们需要找出它是如何发生的
案例1：
当我查看logback 1.2.3的Maven Reportor时，我发现它已经对SLF4J具有依赖性。
因此，当您加载logback 1.2.3时，SLF4J将自动添加
因此，如果您这样做，则无需将其他SLF4J添加到POM中。
请参考链接以获取更多详细信息 - 编译下降：
案例2：
查看wildfly/modules/system/layers/base/org/slf4j
文件夹查看是否已经添加了任何SLF4J罐子。如果是这样，您只需要编译
时SLF4J添加<scope>compile</scope>
