构建 Gradle 项目时出现以下错误：

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/Users/qliu/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.0.6/ba738848da3e6fffa0107771c75546eb6d407f3c/logback-classic-1.0.6.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/Users/qliu/.gradle/caches/modules-2/files-2.1/uk.org.lidalia/slf4j-test/1.1.0/f4f523049e041dea673bd421d7b0d61fb5e49548/slf4j-test-1.1.0.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [ch.qos.logback.classic.selector.DefaultContextSelector]

还有我的 Gradle 构建文件：

dependencies {
        // for output logger messages
        compile group: 'log4j', name: 'log4j', version: '1.2.17'

        // for testing outputed logger messages
        compile group: 'uk.org.lidalia', name: 'slf4j-test', version: '1.1.0'
}

我如何删除警告？
