使用電子表格服務會引發“ 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工作表的標題。

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());
        }

    }
}

但我得到如下異常：

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)

我沒有發現此錯誤的任何原因，請幫助我解決該問題以獲取電子表格數據。

我正在使用以下主要罐子：

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

等等

com.google.common.collect是Guava：Java 1.6+的Google核心庫的一部分。 您可能需要下載並安裝它們... guava-17.0.jar似乎是guava jar的最新版本...
