NoSuchMethodError: optionsBuilder.build().getService() in Google Cloud Storage

问题

I am trying to connect to google bucket to upload a file.

StorageOptions.Builder optionsBuilder = StorageOptions.newBuilder();

optionsBuilder.setCredentials(GoogleCredentials.getApplicationDefault());

Storage storage = optionsBuilder.build().getService();

I have provided service account in environment variables and when i looked into optionsBuilder.build() the credentials are added correctly including projectId, credentials etc. but service property is showing null.

its giving error for optionsBuilder.build().getService() and returns

com.google.api.client.googleapis.services.json.AbstractGoogleJsonClient$Builder.setBatchPath(Ljava/lang/String;)Lcom/google/api/client/googleapis/services/AbstractGoogleClient$Builder;

Here are the maven dependencies related to google cloud

<dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-datastore</artifactId>
        <exclusions>
            <exclusion>
                <groupId>com.google.guava</groupId>
                <artifactId>guava</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-storage</artifactId>
    </dependency>

Letme know if there is any workaround for it
