AWS 实例创建错误

Question

我在通过 eclipse 在 AWS 中创建实例时遇到以下错误。

exception in thread "main" com.amazonaws.AmazonClientException: Unable to load AWS credentials from any provider in the chain
    at com.amazonaws.auth.AWSCredentialsProviderChain.getCredentials(AWSCredentialsProviderChain.java:117)
    at com.amazonaws.services.opsworks.AWSOpsWorksClient.invoke(AWSOpsWorksClient.java:3574)
    at com.amazonaws.services.opsworks.AWSOpsWorksClient.createInstance(AWSOpsWorksClient.java:2098)
    at AwsConsoleApp.main(AwsConsoleApp.java:154)

我的代码如下：

String az=new String("ec2.us-east-1.amazonaws.com");
cir.setAvailabilityZone(az);
String ami_id=new String("ami-864d84ee");
cir.setAmiId(ami_id);
CreateInstanceResult cr=awoc.createInstance(cir);

请帮帮我。

您似乎需要提供凭证才能访问您的 AWS 账户：
