아파치 빔 틀 : 런타임 컨텍스트 오류

나는 현재 Google tutorial

같은 아파치 빔 SDK의 V2.1.0를 기반으로 데이터 흐름 템플릿을 만들려고 해요

이는 경우 내 메인 클래스

public static void main(String[] args) { 

    // Initialize options 
    DispatcherOptions options = PipelineOptionsFactory.fromArgs(args).withValidation().as(DispatcherOptions.class); 

    // Create pipeline 
    Pipeline pipeline = Pipeline.create(options); 

    // Get messages 
    PCollection<PubsubMessage> messages = pipeline.apply("ReadMain", PubsubIO.readMessages().fromSubscription(options.getSubscription())); 

    }

입니다 I 나는이 방법을 사용하는 경우이 작업 년대

mvn compile exec:java \ 
-Dexec.mainClass=com.example.myclass \ 
-Dexec.args="--runner=DataflowRunner \ 
       --project=[YOUR_PROJECT_ID] \ 
       --stagingLocation=gs://[YOUR_BUCKET_NAME]/staging \ 
       --templateLocation=gs://[YOUR_BUCKET_NAME]/templates/MyTemplate"

명령을 실행

하지만

PubsubIO.readMessages().fromSubscription(options.getSubscription()));

오류
