Scala 为什么错误与跨版本后缀冲突?
当我试图在sbt中编译Scala项目时,我遇到了这个错误Scala 为什么错误与跨版本后缀冲突?,scala,sbt,akka,spray,Scala,Sbt,Akka,Spray,当我试图在sbt中编译Scala项目时,我遇到了这个错误 Modules were resolved with conflicting cross-version suffixes in {file:/home/seven3n/caja/Flujo_de_caja/}flujo_de_caja: [error] com.typesafe.akka:akka-actor _2.11, _2.10 [error] org.scalaz:scalaz-effect _2.10, _2.11

[error] (*:update) Conflicting cross-version suffixes in: com.typesafe.akka:akka-actor, org.scalaz:scalaz-effect, org.scalaz:scalaz-core
这是我的build.sbt文件:
scalaVersion := "2.11.0"
resolvers ++= Seq(
"Sonatype snapshots repository" at "https://oss.sonatype.org/content/repositories/snapshots/",
"Spray repository" at "http://repo.spray.io/",
"Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"
)
libraryDependencies ++= {
val akkaVersion = "2.3.2"
val sprayVersion = "1.3.1-20140423"
val sprayJsonVersion = "1.2.6"
val reactiveMongoVersion = "0.11.0-SNAPSHOT"
val scalaTestVersion = "2.1.5"
val specs2Version = "2.3.11"
val foloneVersion = "0.12-SNAPSHOT"
Seq(
"com.typesafe.akka" %% "akka-actor" % akkaVersion,
"com.typesafe.akka" %% "akka-testkit" % akkaVersion,
"io.spray" %% "spray-can" % sprayVersion,
"io.spray" %% "spray-routing" % sprayVersion,
"io.spray" %% "spray-testkit" % sprayVersion,
"io.spray" %% "spray-json" % sprayJsonVersion,
"org.reactivemongo" % "reactivemongo_2.10" % reactiveMongoVersion,
"org.scalatest" %% "scalatest" % scalaTestVersion % "test",
"org.specs2" %% "specs2" % specs2Version % "test",
"info.folone" % "poi-scala_2.10" % foloneVersion
)
}
有什么建议吗?出现冲突的原因是:
%%
操作符
"org.reactivemongo" %% "reactivemongo" % reactiveMongoVersion,
"info.folone" %% "poi-scala" % foloneVersion
这就是
%%
运算符的用途。将声明的Scala版本(在您的示例中为2.11)附加到工件名称。我尝试使用%%,但没有成功。我已使用
("org.reactivemongo" % "reactivemongo" % reactiveMongoVersion)
.exclude("com.typesafe.akka", "akka-actor_2.10")
.exclude("org.scalaz", "scalaz-effect")
.exclude("org.scalaz", "scalaz-core")
我也遇到了同样的问题,我只是从我的sbt文件中删除了scalaVersion标记并修改了行
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.6.0"
到
问题消失了。要调查谁是呼叫者,您可以使用插件,但这是查看
target/scala-2.*/resolution cache/reports/
更简单的方法。
每个配置都有Ivy的分辨率报告。
查找*-compile.xml
和*-test.xml
并搜索冲突库。
你可以看到类似的例子
<module organisation="com.github.nscala-time" name="nscala-time_2.11">
...
<caller organisation="com.tumblr" name="colossus-metrics_2.11" conf="compile, runtime" rev="1.2.0" rev-constraint-default="1.2.0" rev-constraint-dynamic="1.2.0" callerrev="0.7.2-RC1"/>
...
</module>
...
...
这应该会告诉您模块的调用者。不,那些库无法通过%%operator:(@rodrigocifuntesgómez)找到,这意味着它们还没有迁移到Scala 2.11。我会选择2.10(
scalaVersion:=“2.10.4”
)目前,另一种选择是开始从两个2.10库中排除可传递依赖项,这很可能会因为其他类路径冲突而给您带来麻烦。最有可能是在运行时。这个答案在我看来是正确的。如果您同意,Rodrigo,如果您批准这一点,将有助于其他患者(当然,这会奖励作者花时间准备答案)。
<module organisation="com.github.nscala-time" name="nscala-time_2.11">
