ElasticBeanstalk客户端

Question

我尝试开发一个弹性beanstalk客户端接口,通过它连接到我的亚马逊帐户elasticbeanstalk.我使用了脚本文件中的帐户凭据credentials.Csl.我从Google Chrome注册了我的帐户但是我收到了错误.这是我的代码.

package PFE;


import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.elasticbeanstalk.AWSElasticBeanstalk;
import com.amazonaws.services.elasticbeanstalk.AWSElasticBeanstalkClient;
import com.amazonaws.services.elasticbeanstalk.model.CheckDNSAvailabilityResult;

public class Sample {

    static AWSElasticBeanstalk      eb;

    private static void init()throws Exception{


 /*
  * The ProfileCredentialsProvider will return your [default]
  * credential profile by reading from the credentials file located at
  * (~/.aws/credentials).
  */
    AWSCredentials credentials = null;

    try {

        credentials = new ProfileCredentialsProvider().getCredentials();

    } catch (Exception e) {
        throw new AmazonClientException(
             "Cannot load the credentials from the credential profiles file. " +
             "Please make sure that your credentials file is at the correct " +
             "location (~/.aws/credentials), and is in valid format.",
             e);
    }

    eb = new AWSElasticBeanstalkClient(credentials);
    Region usWest2 = Region.getRegion(Regions.US_WEST_2);
    eb.setRegion(usWest2);
}

public static void main(String[] args) throws Exception {

    init();    
    try {            
        CheckDNSAvailabilityResult c= eb.checkDNSAvailability(null);

        System.out.println("You have access to " + c.getAvailable() +
                           " Availability Zones.")

        eb.createStorageLocation();

    } catch (AmazonServiceException ase) {
        System.out.println("Caught Exception: " + ase.getMessage());
        System.out.println("Reponse Status Code: " + ase.getStatusCode());
        System.out.println("Error Code: " + ase.getErrorCode());
       System.out.println("Request ID: " + ase.getRequestId());
    }                  
}

}

以下是运行项目时出现的错误

 Exception in thread "main" java.lang.NoClassDefFoundError:org/apache/commons/logging/LogFactory at com.amazonaws.auth.profile.ProfilesConfigFile.<clinit>(ProfilesConfigFile.java:62) at com.amazonaws.auth.profile.ProfileCredentialsProvider.getCredentials(ProfileCredentialsProvider.java:106)

我认为问题出在org.apache.commons.logging.LogFactory库中,所以我下载了它并将其添加到我引用的库中,但我仍然遇到相同的错误.

我在尝试制作 SQS 示例时遇到了同样的错误...我的解决方案是：不要将 AWS SDK for Java 添加为外部 jar

但作为一个图书馆。
