If, for some reason, you have decided to proceed with these code samples without the tutorial, please go through the following steps and set up the required preconditions.

### Select your project and enable the Retail API
## Prepare your work environment

Google Cloud organizes resources into projects. This lets you
collect all the related resources for a single application in one place.
To prepare the work environment you should perform the following steps:
- Create a service account.
- Create a service account key and set it to authorize your calls to the Retail API.
- Install Google Cloud Retail library.

If you don't have a Google Cloud project yet or you're not the owner of an existing one, you can
[create a new project](https://console.cloud.google.com/projectcreate).
### There are two ways to set up your work environment:

- If you want to **speed up the process** of setting up the working environment, run the script java-retail/samples/interactive-tutorials/samples/interactive-tutorials/src/main/java/user_environment_setup.sh and skip the next **set up the work environment step-by-step** tutorial step:

After the project is created, set your PROJECT_ID to a ```project``` variable.
1. Run the following command in Terminal:
```bash
gcloud config set project <YOUR_PROJECT_ID>
bash java-retail/samples/interactive-tutorials/user_environment_setup.sh
```

1. To check that the Retail API is enabled for your Project, go to the [Admin Console](https://console.cloud.google.com/ai/retail/).
- If you want to perform the environment set up step by step along with getting the explanation you should proceed with the next tutorial step.

## Set up the work environment step-by-step

### Create service account

To access the Retail API, you must create a service account.
To access the Retail API, you must create a service account. Check that you are an owner of your Google Cloud project on the [IAM page](https://console.cloud.google.com/iam-admin/iam).

1. To create a service account, follow this [instruction](https://cloud.google.com/retail/docs/setting-up#service-account)
1. To create a service account, perform the following command:

1. Find your service account on the [IAM page](https://console.cloud.google.com/iam-admin/iam),
click `Edit` icon, add the 'Storage Admin' and 'BigQuery Admin' roles. It may take some time for changes to apply.
```bash
gcloud iam service-accounts create <YOUR_SERVICE_ACCOUNT_ID>
```

1. Copy the service account email in the Principal field.
1. Assign the needed roles to your service account:

### Set up authentication
```bash
for role in {retail.admin,editor,bigquery.admin}
do gcloud projects add-iam-policy-binding <YOUR_PROJECT_ID> --member="serviceAccount:<YOUR_SERVICE_ACCOUNT_ID>@<YOUR_PROJECT_ID>.iam.gserviceaccount.com" --role="roles/${role}"
done
```

To run a code sample from the Cloud Shell, you need to be authenticated using the service account credentials.
1. Use the following command to show the service account email:

1. Login with your user credentials.
```bash
gcloud auth login
gcloud iam service-accounts list|grep <YOUR_SERVICE_ACCOUNT_ID>
```

1. Type `Y` and press **Enter**. Click the link in a Terminal. A browser window should appear asking you to log in using your Gmail account.
Copy the service account email.

1. Provide the Google Auth Library with access to your credentials and paste the code from the browser to the Terminal.

1. Upload your service account key JSON file and use it to activate the service account:

### Set the GOOGLE_CLOUD_PROJECT environment variable
### Google Cloud Retail libraries

Learn more about the [Java Google Cloud Retail library](https://googleapis.dev/java/google-cloud-retail/latest/index.html).

## Congrats! You have configured your work environment

You will run the code samples in your own Google Cloud project. To use the **project_id** in every request to the Retail API, you should first specify them as environment variables.
1. Check that you are in the directory with code samples.

1. Find the project ID in the Project Info card displayed on **Home/Dashboard**.
The code samples for each of the Retail services are stored in different directories.

Go to the code samples directory, your starting point to run more commands.

1. Set the **project_id** with the following command:
```bash
export GOOGLE_CLOUD_PROJECT=<YOUR_PROJECT_ID>
cd java-retail/samples/interactive-tutorials/
```

### Upload catalog data to Cloud Storage
There is a java-retail/samples/interactive-tutorials/src/main/resources/products.json file with valid products prepared in the `resources` directory.

There is a JSON file with valid products prepared in the `product` directory:
`product/resources/products.json`.
The other file, java-retail/samples/interactive-tutorials/src/main/resources/products_some_invalid.json, contains both valid and invalid products. You will use it to check the error handling.

Another file, `product/resources/products_some_invalid.json`, contains both valid and invalid products, and you will use it to check the error handling.
- If you want to **speed up the process**, run the following script in the Terminal directory to import all products to catalog and skip the next **Prepare the catalog data step-by-step** tutorial step:

In your own project, create a Cloud Storage bucket and put the JSON file there.

- If you want to upload products to the catalog step by step along with getting the explanation, you should proceed with the next tutorial step.

## Prepare the catalog data step-by-step

### Upload catalog data to Cloud Storage

In your own project you need to create a Cloud Storage bucket and put the JSON file there.
The bucket name must be unique. For convenience, you can name it `<YOUR_PROJECT_ID>_<TIMESTAMP>`.

1. To create the bucket and upload the JSON file, run the following command in the Terminal:
<!--TODO update with the correct file path when will be merged-->
1. The code samples for each of the Retail services are stored in different directories.

Go to the code samples directory, your starting point to run more commands.

```bash
pmvn compile exec:java -Dexec.mainClass=CreateGcsBucket
cd java-retail/samples/interactive-tutorials
```

1. To create the bucket and upload the JSON file, open java-retail/samples/interactive-tutorials/src/main/java/product/setup/ProductsCreateGcsBucket.java file

1. Go to the **product** directory and run the following command in the Terminal:

```bash
mvn compile exec:java
-Dexec.mainClass=product.setup.ProductsCreateGcsBucket
```

Now you can see the bucket is created in the [Cloud Storage](https://console.cloud.google.com/storage/browser), and the files are uploaded.

1. The name of the created Retail Search bucket is printed in the Terminal. Copy the name and set it as the environment variable `BUCKET_NAME`:
1. The name of the created Cloud Storage bucket is shown in the Terminal.

```
The gcs bucket <YOUR_PROJECT_ID>_<TIMESTAMP> was created
```

Copy the name and set it as the environment variable `BUCKET_NAME`:

```bash
export BUCKET_NAME=<YOUR_BUCKET_NAME>
```

### Import products to the Retail Catalog

To import the prepared products to a catalog, run the following command in the Terminal:
<!--TODO update with the correct file path when will be merged-->
```bash
pmvn compile exec:java -Dexec.mainClass=ImportProductsGcs
```
To import the prepared products to a catalog, open java-retail/samples/interactive-tutorials/src/main/java/product/ImportProductsGcs.java file and run the following command in the Terminal:

```bash
mvn compile exec:java -Dexec.mainClass=product.ImportProductsGcs
```

## Your Retail catalog is ready to use!
