私はScalaで書かれたAWS-ラムダを持っている小さなプロジェクトを設定しようとしています：assemblyMergeStrategyタイプエラー
javacOptions ++= Seq("-source", "1.8", "-target", "1.8", "-Xlint")
lazy val root = (project in file(".")).
settings(
name := "xxx",
version := "0.1",
scalaVersion := "2.12.3",
retrieveManaged := true
)
libraryDependencies ++= Seq(
"com.amazonaws" % "aws-lambda-java-core" % "1.1.0" % Provided,
"com.amazonaws" % "aws-lambda-java-events" % "1.1.0" % Provided,
"org.scalatest" % "scalatest" % "2.2.6" % Test
)
scalacOptions += "-deprecation"
assemblyMergeStrategy in assembly <<= (assemblyMergeStrategy in assembly) {
(old) => {
case PathList("META-INF", xs @ _*) => MergeStrategy.discard
case x => MergeStrategy.first
}
}
結果に：
xxx/build.sbt:25: error: not found: value assemblyMergeStrategy assemblyMergeStrategy in assembly <<= (assemblyMergeStrategy in assembly) {^[error] Type error in expression
インスピレーションの源はthis blogました。 Also tried the provided version as mergeStrategy might have been replaced by assemblyMergeStrategy。
