java - 使用 Google Cloud Storage 列出存储桶导致 NoSuchMethodError，Java AppEngine

Question

试图只列出我的 Google Cloud Storage 项目中的存储桶，但不太明白为什么我不断收到以下错误:

java.lang.NoSuchMethodError: com.google.api.services.storage.model.Bucket.getIamConfiguration()Lcom/google/api/services/storage/model/Bucket$IamConfiguration;

我正在使用以下 servlet 对其进行测试:

package servlets;

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.google.cloud.storage.Bucket;
import com.google.cloud.storage.Storage;
import com.google.cloud.storage.StorageOptions;

@WebServlet("/Test")
public class Test extends HttpServlet {
    private static final long serialVersionUID = 1L;

    public Test() {
        super();
    }


    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

        Storage storage = StorageOptions.getDefaultInstance().getService();
        for (Bucket bucket : storage.list().iterateAll()) { //this line is giving the error
            response.getWriter().write(bucket.getName());
        }
    }
}

在我的 pom 中我有:

<dependency>
    <groupId>com.google.appengine.tools</groupId>
    <artifactId>appengine-gcs-client</artifactId>
    <version>0.8</version>
</dependency>

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-storage</artifactId>
    <version>1.64.0</version>
</dependency>

这个特定示例不需要前一个依赖项，但我需要它用于应用程序的另一部分，我怀疑这可能是问题所在。任何想法可能出了什么问题？

因为您使用的是 Java:以防您愿意尝试 google-cloud-nio ，它有一个 listBuckets 方法，如下所示:

Page<Bucket> buckets = CloudStorageFileSystem.listBuckets("my-project");
Iterator<Bucket> bucketIterator = buckets.iterateAll();
while (bucketIterator.hasNext()) {
  Bucket bucket = bucketIterator.next();
  // do something with the bucket
}
