SBT 의존성을

Question

를 해결하지 못하는 제가

name := "TweetStream" 
version := "1.0" 

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2" 
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.5.2" 
libraryDependencies += "com.google.code.gson" %% "gson" % "2.7" 
libraryDependencies += "org.twitter4j" %% "twitter4j-core" % "4.0.4" 

든 SBT 도구 아래로 미해결 종속성 초래 받는다는 저장소 경로에 xxx_2.10 추가되어 다음과 같은 간단한 SBT 파일이있다.

다음 게시판에서 제안한 것처럼 아이비 폴더를 삭제하려고 시도했지만 도움이되지 않았습니다.

~/.ivy2/cache$ rm -r commons-logging/ 

Answer 1

스칼라 버전을 지정하지 않으므로 기본값은 2.10이며 원하는 것은 아닐 수 있습니다. 내가 원하는 의존성이 2.10 용으로 게시되었는지는 모르겠다.

Gson은 Scala 라이브러리처럼 게시되지 않으므로 단일 %을 통해 추가해야합니다. twitter4j에 대해서는 잘 모르지만, 그 이름은 스칼라 라이브러리가 아니라 자바라고 제안합니다. 다음과 같이 시도해보십시오. build.sbt

name := "TweetStream" 
scalaVersion := "2.11.8" // provide Scala version 
version := "1.0" 

libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.2" 
libraryDependencies += "org.apache.spark" %% "spark-streaming" % "1.5.2" 
libraryDependencies += "com.google.code.gson" % "gson" % "2.7" // notice single `%` instead of `%%` 
libraryDependencies += "org.twitter4j" % "twitter4j-core" % "4.0.4" // same here
