Why do I get conflicting cross-version in sbt on one environment but not another?

Question

I have an sbt project with these dependencies:

libraryDependencies ++= Seq(
  \"org.scalatra\"           %% \"scalatra\"          % ScalatraVersion,
  \"org.         


        

Answer 1

Given the pom for com.github.nikita-volkov:embrace, I'm guessing it's due to the use of version ranges combined with caching:

<dependency>
  <groupId>org.scala-lang</groupId>
  <artifactId>scala-compiler</artifactId>
  <version>[2.10,3)</version>
  <scope>compile</scope>
</dependency>

Particularly given that Scala 2.12.0-M1 was release yesterday:

• http://www.scala-lang.org/news/2.12.0-M1

To fix the inconsistency you want to clear your ivy cache:

rm -r ~/.ivy2/cache

However you also want to fix the version of scala-compiler use, and you want it to match your configured scalaVersion:

dependencyOverrides += "org.scala-lang" % "scala-compiler" % scalaVersion.value

See more details in the Overriding a version section of the Library Management docs.
