'How to resolve class file for com.google.cloud.Service not found

I am Trying to upload JSON data to gcs. As I did not use google cloud previously I started with uploading random String to gcs but I got stuck at the beginning itself while creating a Storage service object

Maven dependency

 <dependency>
   <groupId>com.google.cloud</groupId>
   <artifactId>google-cloud-storage</artifactId>
   <version>1.70.0</version>
 </dependency>


import com.google.cloud.storage.*;
Storage storage = StorageOptions.getDefaultInstance().getService();
    BlobId blobId = BlobId.of("bucket_name", "test_upload/test.txt");
    BlobInfo blobInfo = BlobInfo.newBuilder(blobId).setContentType("text/plain").build();
    Blob blob = storage.create(blobInfo, "Hello, Cloud Storage!".getBytes(UTF_8));
    System.out.println(blob);

Compile Time Error:

If someone is using module-info.java then you need to have these two dependencies:

    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-core</artifactId>
        <version>2.6.1</version>
    </dependency>

    <dependency>
        <groupId>com.google.cloud</groupId>
        <artifactId>google-cloud-firestore</artifactId>
        <version>3.0.21</version>
    </dependency>

and in your module-info.java do something like:

open module ModuleName {
    ...
    requires google.cloud.core;
    requires google.cloud.firestore;
    requires com.google.auth;
    requires com.google.auth.oauth2;
    ...
}

if you are using intellij, then it will ask you to do google.cloud.firestore and com.google.auth.oauth2 but this won't work as these depend on google.cloud.core and com.google.auth.

Did you try to include this dependency in your pom.xml ? 

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-core</artifactId>
    <version>1.70.0</version>
</dependency>

my understanding is that you can’t upload files to the gcp container using java, and the stack trace is showing that maven failing at compilation time.

Well, You can try 2 things:

1.- Make sure that you Authentication settings are good, You can follow the steps in the link[1]. 2.- Configure you Maven installation according the gcp instructions[2].
