SLF4J Warning: Class path contains multiple SLF4J bindings.

[tianxiao-ma]

使用autoconfig的_maven_插件时，报_SLF4J multiple bindings_警告。

插件版本：

<groupId>com.alibaba.citrus.tool</groupId>
<artifactId>autoconfig-maven-plugin</artifactId>
<version>1.2</version>

警告信息如下：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/tianxiao/Dev/m2_repo/com/alibaba/citrus/tool/antx-autoconfig/1.2/antx-autoconfig-1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/tianxiao/Dev/m2_repo/com/alibaba/citrus/tool/antx-autoexpand/1.2/antx-autoexpand-1.2.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

从警告信息中可以看出，是antx-autoconfig-1.2.jar和antx-autoexpand-1.2.jar这两个jar同时包含了StaticLoggerBinder这个类导致的。
