Question

我正在尝试使用以下代码从eclipse运行emr集群：

    RunJobFlowRequest runFlowRequest = new RunJobFlowRequest()
            .withName("ExtractCollocations" + UUID.randomUUID())
            .withInstances(instances)
            .withSteps(countStepConfig1, countStepConfig2, countStepConfig3, countStepConfig4)
            .withLogUri("s3n://"+ Bucket_name + "/logs/")
            .withServiceRole("EMR_DefaultRole")
            .withJobFlowRole("EMR_EC2_DefaultRole");

并收到错误：

Exception in thread "main" java.lang.NoSuchMethodError: com.amazonaws.services.elasticmapreduce.model.RunJobFlowRequest.withServiceRole(Ljava/lang/String;)Lcom/amazonaws/services/elasticmapreduce/model/RunJobFlowRequest;
    at LocalApp.runCluster(LocalApp.java:213)
    at LocalApp.main(LocalApp.java:52)

如果我删除行“withServiceRole（”EMR_DefaultRole“）”它要求服务角色

显然问题出在maven项目上。我已经开通了新的AWS Java Project，但它确实有效。

AWS服务角色
