Question

我有一个scala项目，可以编译并且可以无错误地执行。我在我的模块的build.sbt文件中添加了直径依赖：

libraryDependencies ++= Seq(
    // some other dependencies here
    // then diameter dependencies
    "org.mobicents.diameter" % "jdiameter-api" % "1.7.0.106",
    "org.mobicents.diameter" % "jdiameter-impl" % "1.7.0.106"
)

项目仍在编译但无法运行：

[app] $ compile
[success] Total time: 1 s, completed Sep 28, 2016 2:54:36 PM
[app] $ run

SLF4J: Class path contains multiple SLF4J bindings.

我不明白添加这两个依赖项会如何破坏应用程序。我可以在.ivy2缓存中看到下载的jar，以便解决新的依赖关系。

我该如何解决这个问题？完整输出说：

java.lang.reflect.InvocationTargetException

非常感谢你的帮助

更新

如果我只添加此依赖项

"org.mobicents.diameter" % "jdiameter-api" % "1.7.0.106"

它有效：）

但我需要两个:(

Answer 1

看起来两个依赖项都添加了自己的logger实现，并且它们在运行时发生冲突。

尝试从两个中的一个中排除它，例如：

libraryDependencies ++= Seq(
    "org.mobicents.diameter" % "jdiameter-api" % "1.7.0.106",
    "org.mobicents.diameter" % "jdiameter-impl" % "1.7.0.106" exclude("org.slf4j", "slf4j-jdk14")
)

向build.sbt添加依赖项后，Scala运行失败
