如何修复接口中的“静态方法需要-target:jvm-1.8"?在Scala应用程序中? [英] How to fix "static methods in interface require -target:jvm-1.8" in Scala application?

问题描述

我编写了以下代码:

import software.amazon.awssdk.services.cloudwatchlogs.CloudWatchLogsClient

class Test() extends CloudWatchLogsClient {
  CloudWatchLogsClient.builder().build()
  def close():Unit = {
    println("test")
  }

  def serviceName(): String  = "serviceName"
  CloudWatchLogsClient.create()
}

在编译时，出现以下错误:

When it comes to compiling , I get the following error:

Static methods in interface require -target:jvm-1.8
  CloudWatchLogsClient.builder().build()

最后，我在build.sbt文件中使用了以下依赖项

Finally, I used the following dependencies in my build.sbt file

libraryDependencies += "software.amazon.awssdk" % "cloudwatch" % "2.15.40",
libraryDependencies += "software.amazon.awssdk" % "cloudwatchlogs" % "2.15.40"

Java版本为1.8，Scala版本为2.11.12.知道了，如何解决这个问题?

Java version is 1.8, and Scala version is 2.11.12. Any idea, how to fix this please?

推荐答案

请在您的build.sbt中添加以下内容:

Please add the following into your build.sbt:

scalacOptions in ThisBuild += "-target:jvm-1.8"

在Gradle的接口中的静态方法需要-target:jvm-1.8 .
