Scala 使用SBT引用Git库时无法解析包

我试图用Git引用一个定制的ScalaCheck，我的

build.sbt

文件如下

lazy val root = (project in file("."))
  .settings(
    name := "myproject",
    version := "1.0",
    scalaVersion := "2.11.8",
    libraryDependencies ++= Seq(/*other dependencies*/)
  )
  .dependsOn(sc)

lazy val sc = RootProject(uri("https://github.com/<user>/scalacheck.git"))
version in sc := "1.14.0-SNAPSHOT"

此外，到目前为止，只有在使用Scala 2.12版时，我才能做到这一点，但我需要使用2.11版，因为其他一些依赖项仅支持这一点。使用2.11它根本无法解决依赖关系

我在SBT版本0.13.13

这是我的sbt输出

.sbt/0.13/staging/ec35d052aa233b077b77a/scalacheck

包含完整的repo和我认为是目标目录中的一个构建，但大多数是指Scala版本2.12的构建

后续编辑：我认为SBT的这个bug报告涉及到了

假设您的

/scalacheck.git

是原始的

rickynils/scalacheck.git

的分支，问题是scalacheck的当前主分支 是

由于您的

scalaVersion

为2.11.8，因此不支持当前版本的scalacheck

因此，将

build.sbt

的

scalaVersion

更改为2.12.0将解决问题

此外，您还可以使用

sbt projects

检查scalacheck中是否包含三个项目：

$ sbt projects
  js
  jvm
* scalacheck

js

用于

scalajs

，因此您需要的是

jvm

因此，您必须使用

ProjectRef

而不是

RootProject

来指定项目

lazy val root = (project in file("."))
  .settings(
    name := "myproject",
    version := "1.0",
    scalaVersion := "2.12.0",
    libraryDependencies ++= Seq(/*other dependencies*/)
  )
  .dependsOn(sc)

lazy val sc = ProjectRef(uri("https://github.com/<user>/scalacheck.git"),"jvm")
version in sc := "1.14.0-SNAPSHOT"

---

首先，ScalaCheck build.sbt中的

crossscalaversations

设置不会解决这个问题吗？其次，虽然sbt确实找到了scalacheck，但我仍然在Main中得到导入错误

scalacheck不是org的一部分。另外，我可以使用sbt指定较旧的ScalaCheck版本而不是使用2.12（因为我的一个依赖项需要2.11）吗？@davl我更新了答案，如何指定较旧的ScalaCheck并修复导入错误。是的，正如您所说，
crossscalaversations
是在scalacheck的
build.sbt
中指定的，因此它应该在
2.11.8
中运行，但可能
crossscalaversations
不打算用于
rootprojectref
或
ProjectRef
，而只用于部署。我不知道真相。
lazy val root = (project in file("."))
  .settings(
    name := "myproject",
    version := "1.0",
    scalaVersion := "2.12.0",
    libraryDependencies ++= Seq(/*other dependencies*/)
  )
  .dependsOn(sc)

lazy val sc = ProjectRef(uri("https://github.com/<user>/scalacheck.git"),"jvm")
version in sc := "1.14.0-SNAPSHOT"

ProjectRef(uri("https://github.com/rickynils/scalacheck.git#1.13.4"),"jvm")
