使用電子表格服務引發「java.lang.NoSuchMethodError」異常

Question

我正在使用以下代碼來獲取電子表格並打印表格的標題。

import com.google.gdata.client.spreadsheet.*; 
import com.google.gdata.data.spreadsheet.*; 
import com.google.gdata.util.*; 

import java.io.IOException; 
import java.net.*; 
import java.util.*; 

public class MySpreadsheetIntegration { 
    public static void main(String[] args) 
      throws AuthenticationException, MalformedURLException, IOException, ServiceException { 
     SpreadsheetService service = 
       new SpreadsheetService("MySpreadsheetIntegration-v1"); 

     URL SPREADSHEET_FEED_URL = new URL(
       "spreadsheet URL"); 

     SpreadsheetFeed feed = service.getFeed(SPREADSHEET_FEED_URL, SpreadsheetFeed.class); 
     List<SpreadsheetEntry> spreadsheets = feed.getEntries(); 

     for (SpreadsheetEntry spreadsheet : spreadsheets) { 
      // Print the title of this spreadsheet to the screen 
      System.out.println(spreadsheet.getTitle().getPlainText()); 
     } 

    } 
} 

，但我得到的例外如下：

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.collect.ImmutableSet.copyOf([Ljava/lang/Object;)Lcom/google/common/collect/ImmutableSet; 
    at com.google.gdata.wireformats.AltFormat$Builder.setAcceptableTypes(AltFormat.java:399)

    at com.intellij.rt.execution.application.AppMain.main(AppMain.java:134) 

我沒有找到任何原因這個錯誤，請幫我解決問題，以獲取電子表格數據。

我使用的主要有以下罐：

gdata-spreadsheet-3.0 
mailapi.jar 
gdata-core-1.0 

等

com.google.common.collect是Guava: Google Core Libraries for Java 1.6+的一部分。您可能需要下載並安裝它們... guava-17.0.jar似乎是番石榴罐的最新版本...
