我正在以下列格式在谷歌云中存儲對象bucketname/UUID/object例如，我在谷歌云中有一個對象，存儲為roshanbucket/1fa0e7b4-b551-4e5c-a491-8d86f06a1eef/test.txt這是我用來返回對象名稱的方法public String getFileName(String bucketName, String uuid) {    final String[] fileName = {null};    Page<Blob> blobs = storage.list(bucketName, BlobListOption.prefix(uuid));    blobs.iterateAll().forEach(        blob -> fileName[0] = blob.getName()//.substring(blob.getName().lastIndexOf('/') + 1)    );    return fileName[0];  }這是測試方法@Test  public void testGetFileName(){    String fileName = googleCloudStorage.getFileName("roshanbucket", "1fa0e7b4-b551-4e5c-a491-8d86f06a1eef");    System.out.println(fileName);  }當(dāng)我運行測試時，它給了我以下錯誤java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)Vat com.google.cloud.storage.StorageImpl.optionMap(StorageImpl.java:1279)at com.google.cloud.storage.StorageImpl.optionMap(StorageImpl.java:1268)at com.google.cloud.storage.StorageImpl.optionMap(StorageImpl.java:1301)at com.google.cloud.storage.StorageImpl.list(StorageImpl.java:306)at services.fileserver.GoogleCloudStorage.getFileName(GoogleCloudStorage.java:76)at services.fileserver.GoogleCloudStorageTest.testDownloadLink(GoogleCloudStorageTest.java:40)at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)如何解決此問題？
