Question

在我的Java项目中，我尝试通过点击this链接将Java kinesis akka流添加为Source，但是他的项目无法编译；

    Error:(22, 53) java: cannot access scala.Serializable
      class file for scala.Serializable not found

在此行ShardSettings.create

    final ShardSettings settings = ShardSettings.create("test-stream", "shard-id")
            .withShardIteratorType(ShardIteratorType.LATEST)
            .withRefreshInterval(1L, TimeUnit.SECONDS)
            .withLimit(500);

我尝试将scala lang-library添加到我的build.gradle中，但是没有运气。这是我的build.gradle文件；

plugins {
    id 'java'
    id 'scala'
}

group 'org.example'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'
    implementation 'org.scala-lang:scala-library:2.12.10'
    compile 'org.scala-lang:scala-library:2.12.10'
    compile group: 'com.typesafe.akka', name: 'akka-stream_2.13', version: '2.6.1'
    compile group: 'com.lightbend.akka', name: 'akka-stream-alpakka-kinesis_2.12', version: '0.17'
    compile group: 'com.lightbend.akka', name: 'akka-stream-alpakka-s3_2.12', version: '1.1.2'
}

任何人都知道发生了什么事吗？

java：无法访问scala.Serializable类文件，找不到scala.Serializable
