Apache Flink RabbitMq SBT 依赖项失败

Question

我正在尝试将Flink与RabbitMq流连接器一起使用。已尝试所有可能的版本组合，但仍然失败。

这是我的 sbt 构建代码段

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)

Answer 1

您是否尝试过使用相同的 Flink 依赖项版本进行构建？我使用以下 SBT 配置成功构建 （ 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，有一个关于 Flink 项目 SBT 的指南（https://ci.apache.org/projects/flink/flink-docs-master/quickstart/scala_api_quickstart.html#sbt）。
