Question

我在Scala中编辑我的Spark + Kafka应用程序，当我再次尝试编译时，我继续收到消息Failing because of negative scalastyle result。当我更改我的版本时，我仍会收到相同的消息。

这是什么？我该如何解决这个错误？

Answer 1

这是因为我的项目在build.sbt上有这些配置

lazy val compileScalastyle = taskKey[Unit]("compileScalastyle")
lazy val testScalastyle = taskKey[Unit]("testScalastyle")
lazy val root = (project in file("."))
  .settings(commonSettings)
  .settings(scalacOptions ++= customScalacOptions)
  .settings(libraryDependencies ++= customLibraryDependencies)
  .settings(excludeDependencies ++= commonExcludeDependencies)
  .settings(fork in run := true)
  .settings(connectInput in run := true)
  .settings(javaOptions in run ++= customJavaOptions)
  .settings(
    scalastyleFailOnError := true,
    compileScalastyle := scalastyle.in(Compile).toTask("").value,
    (compile in Compile) := ((compile in Compile) dependsOn compileScalastyle).value,
    testScalastyle := scalastyle.in(Test).toTask("").value,
    (test in Test) := ((test in Test) dependsOn testScalastyle).value)

我删除了，错误不再停止编译。

通常可以在一个名为scalastyle-result.xml的文件中找到此错误的原因，在那里您可以找到所有警告以及可能导致此问题的错误

什么意思是“因为负面的scalastyle结果而失败”的消息？
