由于StatibloggerBinder.class中的去重错误，Scala SBT程序集无法合并

Question

运行“SBT程序集”时的问题：

[错误]合并java.lang.runtimeException时遇到3个错误：删除重复：在以下位置找到不同的文件内容：.vlasakakis/.ivy2/cache/ch.qos.logback/logback-classic/jars/logback-classic-1.1.2.jar:org/slf4j/impl/staticMDCBinder.class/users/aris.vlasakakis/.ivy2/cache/org.slf4j/slf4j-log4j12/jars/slf4j-log4j12/jars/slf4j-log4j12-1.6.1.jar:org/slf4j/impl/staticMDCBinder.class deduplicate：在以下文件中可以找到不同的文件内容：-classic-1.1.2.jar:org/slf4j/impl/staticmarkerbinder.class/users/aris.vlasakakis/.ivy2/cache/org.slf4j/slf4j-log4j12/jars/slf4j-log4j12-1.61.jar:org/slf4j/impl/staticmarkerbinder.class at sbtAssembly.Assembly.Assembly.Assembly.Assembly.Assembly.x$1$lzyCompute$1(Assembly.Scala:140)at sbtAssembly.Assembly.x$1$lzyCompute$1(Assembly.Scala:25)at sbtAssembly.Assembly.Assembly.x$1$1(Assembly.Scala:23)at y.assembly$.inputs$1(assembly.scala:57)

...诸如此类

I am using SBT-assembly 0.13.0, and here is the build.sbt

name := "metamorphosis"

version := "0.10.0"

scalaVersion := "2.10.4"

lazy val common = RootProject(file("../"))

//excludeDependencies += "org.apache.logging.log4j"

    exclude("org.slf4j", "slf4j-simple")
)

mainClass in assembly := Some("com.company.kafka.agent.MetamorphosisActor")

关于如何解决这个合并问题，有什么线索吗？

谢谢！

我的错误：

追踪相互冲突的依赖项。例如，我不希望这些类：

org.slf4j/slf4j-log4j12/jars/slf4j-log4j12-1.7.10.jar:org/slf4j/impl/StaticLoggerBinder.class
org.slf4j/slf4j-log4j12/jars/slf4j-log4j12-1.7.10.jar:org/slf4j/impl/StaticMDCBinder.class
org.slf4j/slf4j-log4j12/jars/slf4j-log4j12-1.7.10.jar:org/slf4j/impl/StaticMarkerBinder.class

调用sbt（并确保使用sbt-dependency-graph插件）：
