SLF4jJ 1.8.0-alpha2与Log4j 2.8.2兼容

Question

我已在项目SLF4J中配置了LOG4J2。

当我尝试组合它们的当前最新版本（SLF4J 1.8.0-alpha2和LOG4J 2.8.2）时，我在记录时收到此消息：

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details.
SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions prior to 1.8.
SLF4J: Ignoring binding found at [jar:file:/home/castros/.m2/repository/org/apache/logging/log4j/log4j-slf4j-impl/2.8.2/log4j-slf4j-impl-2.8.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#ignoredBindings for an explanation.

但是，如果我尝试使用最低版本的SLF4J（1.7.24），它会按预期工作。

我对使用SLF4J 1.8.0-alpha2感兴趣，因为它声称已准备好Java 9。

这是我的POM配置的摘录：

我确认没有其他SLF4J绑定，并且没有其他版本的SLF4JAPI低于1.8在类路径中。
