项目参数创建谷歌云桶（Java API）时，未找到

我在尝试使用下面的函数来创建一个谷歌的云斗：项目参数创建谷歌云桶（Java API）时，未找到

def createBucket(bucketName: String, credentials: String): Bucket = { 

    val credentialStream = new ByteArrayInputStream(
     credentials.getBytes(StandardCharsets.UTF_8.name())) 
    val storage = StorageOptions.newBuilder 
     .setCredentials(ServiceAccountCredentials.fromStream(credentialStream)) 
     .build() 
     .getService() 
    storage.create(BucketInfo.newBuilder(bucketName).build()) 
    }

我读的凭证流是一个标准的谷歌云凭据JSON并包含项目ID。不过，我收到了一条错误java.lang.NullPointerException: Required parameter project must be specified如下图所示：

任何想法，这可能是为什么？我试图按照这里列出的API指南：https://cloud.google.com/storage/docs/creating-buckets#storage-create-bucket-java

所以，事实证明，从证书JSON创建存储对象并不会将其分配给JSON引用的项目。必须手动设置：

val storage = StorageOptions.newBuilder 
    .setCredentials(ServiceAccountCredentials.fromStream(credentialStream)) 
    .setProjectId(projectId) 
    .build 
    .getService
