sbt 无法编译 Scala 项目，因为 java.lang.NoSuchMethodError

Question

我是 Scala 的新手，所以任何帮助都将不胜感激。

我使用的是 IntelliJ IDEA 版本：2020.1，sbt.version=1.2.8，jdk1.8.0_251 和 Scala 2.12.8。

当我尝试编译 coursera 项目时，出现以下错误

 compile
[error] stack trace is suppressed; run 'last coursierResolutions' for the full output
[error] (coursierResolutions) java.lang.NoSuchMethodError: lmcoursier.definitions.ToCoursier$.project(Llmcoursier/definitions/Project;)Lcoursier/core/Project;

这是 plugins.sbt 中的 sbt coursier 插件

addSbtPlugin("io.get-coursier" % "sbt-coursier" % "2.0.0-RC3-5")
addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.9.7")

Answer 1

删除 cousier 插件并升级到 sbt 1.3.13 对我有用。

构建属性

sbt.version=1.3.13

插件.sbt

//addSbtPlugin("io.get-coursier" % "sbt-coursier" % "2.0.0-RC3-5")
addSbtPlugin("ch.epfl.scala" % "sbt-scalafix" % "0.9.7")

生成.sbt

course := "bigdata"
assignment := "wikipedia"

生成.sbt

scalaVersion := "2.12.11"
scalacOptions ++= Seq("-language:implicitConversions", "-deprecation")
libraryDependencies ++= Seq(
  "com.novocode" % "junit-interface" % "0.11" % Test,
  ("org.apache.spark" %% "spark-core" % "2.4.3"),
  ("org.apache.spark" %% "spark-sql" % "2.4.3")
)
dependencyOverrides ++= Seq(
  ("com.fasterxml.jackson.core" % "jackson-databind" % "2.6.7")
)

testOptions in Test += Tests.Argument(TestFrameworks.JUnit, "-a", "-v", "-s")

这个答案归功于@JOHN。

Answer 2

我直接在终端中使用 1.2.8 版本的 sbt 二进制文件，它救了我（IDEA 中 sbt shell 的 sbt 版本是 1.3.8）。
