为什么没有检测到传递依赖？

Question

我有基于 SBT 的 Scala 库，我将其发布到 Maven 存储库：

organization := "com.mycompany"
name := "mylib"
version := "0.0.1"
scalaVersion := "2.10.6"
crossScalaVersions := Seq("2.10.6", "2.11.7")
scalacOptions ++= Seq("-feature", "-unchecked", "-deprecation")

libraryDependencies ++= Seq(
  "org.scalaj" %% "scalaj-http" % "2.2.0",
  "org.json4s" %% "json4s-jackson" % "3.3.0",
  "org.slf4j" % "slf4j-api" % "1.7.13",
  "org.slf4j" % "slf4j-simple" % "1.7.13"
)

isSnapshot := true
publishMavenStyle := true
publishTo := {
  Some(s3resolver.value("My Repo", s3("mybucket")).withMavenPatterns)
}

我将此库包含到另一个项目中：

libraryDependencies ++= Seq(
  "com.mycompany" %% "mylib" % "0.0.1"
)

运行sbt sbt-dependency dependencyTree 只显示：

[info] Done updating.
[info] default:another-project_2.10:1.2 [S]
[info]   +-com.mycompany:mylib_2.10:0.0.1
[info]     

我无法查看所有第 3 方依赖项：org.scalaj、org.json4s 等。

编辑：此外，在构建程序集时，uberjar 中也缺少这些依赖项。

部署到 Maven 存储库的 .pom 文件确实包含所有提到的依赖项，而 ~/.ivy2/cache/com.mycompany/mylib_2.10/ivy-0.0.1.xml 没有。

在 mylib/ 中运行 sbt about 显示：

我做错了什么？

Answer 1

您的build.sbt 文件包含该行

publishMavenStyle := true

根据the documentation

一个 POM 由 makePom 操作生成并发布到 存储库而不是 Ivy 文件

我可以假设 ivy.xml 只是没有生成，而您看到的是前一次运行的残留物，当时 publishMavenStyle 尚未（尚未）设置。

由于您的工件已发布到 Maven 存储库中，您是否尝试过从 ~/.ivy2/cache/com.mycompany/mylib_2.10 中删除该工件并检查依赖关系树列表的结果？
