build.sbt中的強制依賴更新

我正在使用breeze-viz 0.3，但需要使用更新版本的jfreechart。根據依賴表 https://mvnrepository.com/artifact/org.scalanlp/breeze-viz_2.10/0.3 build.sbt中的強制依賴更新

jfreechart 1.0.13是默認的，但是1,0.19是更新後的版本，這是我想要的。我添加了行

dependencyOverrides ++= Set(
    "org.jfree" % "jfreechart" % "1.0.19" 
)

並重新運行sbt eclipse，但我仍然在項目中的jfreedchart 1.0.13。我如何強制它使用1.0.19？

這裏是整個build.sbt

import AssemblyKeys._

lazy val commonSettings = Seq(
    version := "1.0", 
    organization := "com.myco",

val sparkVersion = "2.0.0" 
val hbaseVersion = "1.0.0" 
val hadoopVersion = "2.4.0" 
val sprayVersion  = "1.3.2" 

lazy val app = (project in file(".")) 
    .settings(commonSettings: _*) 
    .settings(
    // your settings here 
) 

libraryDependencies <<= scalaVersion { 
    scala_version => Seq(

}

我之前曾與斯卡拉2.11麻煩。我現在應該更新到2.11嗎？

我的天哪。周圍沒有專家？ – bhomass

你可以分享你build.sbt？也，我好奇你爲什麼需要2.10依賴 – Mysterion

您看到jfreedchart 1.0.13，但它是另一個。如果您將看到viz的依賴關係圖，您將會看到，它取決於"jfree" % "jfreechart" % "1.0.13"，而您想要使用"org.jfree" % "jfreechart" % "1.0.19"，它與前一個不相交，因爲它們具有不同的groupId。所以，你需要添加

libraryDependencies += "org.jfree" % "jfreechart" % "1.0.19"

，並排除從即傳遞性依賴，是在你的classpath重複，這樣做：

libraryDependencies += "org.scalanlp" % "breeze-viz_2.10" % "0.3" exclude("jfree", "jfreechart") exclude("jfree", "jcommon")

警告，這可能導致的問題，如果1.0.19不向下兼容1.0.13

你是完全正確的。 1.0.13的組名稱爲「jfree」，但1.0.19仍被列爲更新。怎麼可能？一個具有不同組名稱的庫被作爲更新的版本給出？無論如何，這兩個版本的類名都是相同的，如果我同時擁有這兩個版本，那麼項目中仍然存在衝突。 – bhomass

我已經嘗試過，並且版本衝突仍然存在，正如我所料。 – bhomass

這確實是解決這個問題的方法。我想知道，如果有默認和更新版本有相同的組ID，通常是這樣。排除方法，我認爲，不適用。在這種情況下，你將如何強制它獲得更新版本？ – bhomass
