用java亞馬遜AWS NoSuchFieldError

用java亞馬遜AWS NoSuchFieldError用java亞馬遜AWS NoSuchFieldError

這裏是控制檯日誌：

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchFieldError: INSTANCE

at net.pocketsurvey.cloud.Amazon.listObjectsInBucket(Amazon.java:93)

底線是我的代碼移交到Amazon的S3。代碼如下：

public static ObjectListing listObjectsInBucket(String bucketName, 
    String key) throws Exception { 
    ObjectListing list = null; 
    AmazonS3Client client = Client.s3(Client.DESKTOP); 
    try { 
    boolean b_exists = client.doesBucketExist(bucketName); 
    boolean o_exists = client.doesObjectExist(bucketName, key); 
    if(b_exists) { 
     list = client.listObjects(bucketName, key); 
    } 
    } catch (AmazonServiceException e){ 
    String err = e.getErrorMessage(); 
    e.printStackTrace(); 
    } catch (AmazonClientException e){ 
    e.printStackTrace(); 
    } catch (Exception e){ 
    e.printStackTrace(); 
    } 
    return list; 
    }

'client.listObjects'是炸彈出來的地方。使用

庫包括： AWS-java的SDK-1.10.77.jar HttpClient的-OSGi的4.3.jar org.apache.httpcomponents.httpcore_4.2.1.jar

'b_exists' 是事實，但即使是絕對存在的關鍵字，'o_exists'也會返回false。

我使用的憑據可用於其他事情，例如電子郵件，並下載已知對象，即完整的密鑰字符串。但試圖使用部分密鑰字符串（如「hhs /」）獲取列表，我得到了上面的錯誤。

此外，'捕捉'不抓住它。

該代碼當前在UI線程上運行，但我已經在其自己的線程上嘗試過，結果類似。

該平臺是Windows 7.

任何幫助將不勝感激。

問題排序 - 庫不匹配。

'aws-java-sdk-1.10.77.jar'needs'org.apache.httpcomponents.httpcore_4.4.4.jar'to bein the build path。

我們如何從文檔中瞭解這一點？ @Mike利馬 –
