我正在尝试调试我的sbt依赖地狱，但是几个小时后，我想我只是在我的深度。我的build.sbt是
name := "MyProject"
version := "0.1.0"
scalaVersion := "2.11.8"
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % scalaVersion.value,
"org.scala-lang.modules" %% "scala-xml" % "1.0.5"
)
// ScalaTest
//libraryDependencies += "org.scalactic" %% "scalactic" % "3.0.0"
//libraryDependencies += "org.scalatest" %% "scalatest" % "3.0.0" % "test"
libraryDependencies ++= Seq(
"org.scalatest" %% "scalatest" % "3.0.0" % "test"
exclude("org.scala-lang", "scala-reflect")
exclude("org.scala-lang.modules", "scala-xml")
)
// Linear Algebra Library Breeze
libraryDependencies ++= Seq(
// Last stable release
"org.scalanlp" %% "breeze" % "0.12" exclude("junit", "junit"),
// Native libraries are not included by default. add this if you want them (as of 0.7)
// Native libraries greatly improve performance, but increase jar sizes.
// It also packages various blas implementations, which have licenses that may or may not
// be compatible with the Apache License. No GPL code, as best I know.
"org.scalanlp" %% "breeze-natives" % "0.12",
// The visualization library is distributed separately as well.
// It depends on LGPL code
"org.scalanlp" %% "breeze-viz" % "0.12"
)
resolvers += "Sonatype Releases" at "https://oss.sonatype.org/content/repositories/releases/"
// Plotting with WISP
libraryDependencies ++= Seq(
"com.quantifind" %% "wisp" % "0.0.4"
exclude("org.scala-lang", "scala-compiler")
exclude("org.scala-lang.modules", "scala-parser-combinators")
exclude("org.scala-lang.modules", "scala-xml")
)
// Logging
libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.5.0"
libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.7"

libraryDependencies += "commons-lang" % "commons-lang" % "2.6" // https://mvnrepository.com/artifact/commons-lang/commons-lang
libraryDependencies += "com.google.guava" % "guava" % "19.0" // https://mvnrepository.com/artifact/com.google.guava/guava
我收到了警告
SBT project import
[warn] Multiple dependencies with the same organization/name but different versions. To avoid conflict, pick one version:

还有更多东西。
1）首先，我试图摆脱有关多个版本的警告，我能够摆脱exclude的一些，但我无法摆脱你仍然看到的那些。我究竟做错了什么？我能够使用https://github.com/jrudolph/sbt-dependency-graph来查明WISP正在导入依赖项，而这些依赖项又会导入org.scala-lang.modules:scala-parser-combinators_2.11:1.0.1和org.scala-lang.modules:scala-xml_2.11:1.0.1，但如何解决这些警告？
2）奇怪的是，我还有org.slf4j:slf4j-api的多个版本（通过org.scalanlp：breeze，ch.qos.logback：logback-classic和org.slf4j：slf4j-simple），但我没有得到任何警告。我在运行测试时只收到警告：
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/home/raeg/.ivy2/cache/org.slf4j/slf4j-simple/jars/slf4j-simple-1.7.21.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/home/raeg/.ivy2/cache/ch.qos.logback/logback-classic/jars/logback-classic-1.1.7.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 [org.slf4j.impl.SimpleLoggerFactory]
为什么呢？我试图通过将我的各自build.sbt重写为
"org.scalanlp" %% "breeze" % "0.12" exclude("junit", "junit") exclude("org.slf4j", "slf4j-api"),
和
libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.7" exclude("org.slf4j", "slf4j-api")
但这没有帮助。
3）其他警告如何，我如何摆脱所有这些？还有更多，主要与com/github/fommil/netlib/netlib-native_ref-osx-x86_64/1.1/netlib-native_ref-osx-x86_64-1.1.jar
我正在使用sbt.version = 0.13.8（来自project/build.properties）。
