Question

我正在尝试使用Flink和RabbitMq流连接器。尝试了所有可能的版本组合，但仍然失败。

这是我的sbt构建片段

scalaVersion in ThisBuild := "2.11.7"

val flinkVersion = "1.0.0"

val json4sNative = "org.json4s" %% "json4s-native" % "3.3.0"

val flinkDependencies = Seq(
  "org.apache.flink" %% "flink-scala" % flinkVersion % "provided",
  "org.apache.flink" %% "flink-streaming-scala" % flinkVersion %     "provided",
  "org.apache.flink" %% "flink-connector-rabbitmq" % "0.10.1",
  json4sNative)

您是否尝试使用相同的Flink依赖版本进行构建？我使用以下SBT配置继续构建（sbt assembly）：

name := "flink-sbt-sample"

version := "1.0"

scalaVersion := "2.11.7"

val flinkVersion = "1.0.0"

libraryDependencies ++= Seq(
  "org.apache.flink" %% "flink-scala" % flinkVersion % "provided",
  "org.apache.flink" %% "flink-streaming-scala" % flinkVersion % "provided",
  "org.apache.flink" %% "flink-connector-rabbitmq" % flinkVersion,
  "org.json4s" %% "json4s-native" % "3.3.0"
)

请注意，有一个使用SBT（https://ci.apache.org/projects/flink/flink-docs-master/quickstart/scala_api_quickstart.html#sbt）的Flink项目指南。
