我似乎无法找到下面第一次驱逐的根本原因。如下所示，运行evicted不会提供与其相关的详细信息。
这一切都发生在project / plugins.sbt中添加之后：
libraryDependencies += "io.spray" %% "spray-json" % "1.3.1"
[warn] There may be incompatibilities among your library dependencies.
[warn] Here are some of the libraries that were evicted:

在运行时，我甚至没有尝试使用spray-json就崩溃了，所以在我的sbt构建中如何管理或驱逐这种依赖关系真的不对：
[error] (web-assets:less::jstaskJsOptions) java.lang.NoSuchMethodError: spray.json.JsArray.<init>(Lscala/collection/immutable/List;)V
首先在我的build.sbt中没有明确定义此版本的1.2.6版本，也许它是其他插件所需要的，但如何在没有逐出细节的情况下进行跟踪？我怎样才能理解这次神秘驱逐的细节？
答案 0 :(得分：6)
您可以使用
show externalDependencyClasspath
获取包含所有传递依赖项的toString表示，但它看起来非常麻烦。我建议安装sbt-dependency-graph插件，使dependencyTree任务可用，以可读格式显示您的完整类路径。
