如何在GCP中获取存储桶中的对象列表？

问题描述

我正在尝试获取gcp存储桶中的对象列表，但是我遇到了以下错误，

java.lang.NoSuchMethodError: com.google.common.io.Files.asCharSource(Ljava/io/File;Ljava/nio/charset/Charset;)Lcom/google/common/io/CharSource;

这是我获取列表的代码，我不确定错误到底是什么。

@Test
  def callingGcpBucket() : Unit = {

val storage = StorageOptions.getDefaultInstance.getService
val bucket = storage.get("wmt-omni-datalake-dev-ei-dqa-audit-dev")

println(bucket)

 }
