This is a set of simple samples written in Java, which provide a minimal example of Google Shopping integration within a command line application.

This starter project provides a great place to start your experimentation into the Merchant API.

• Java: Java 8+ is required.
• Maven: Used for dependency management and running the samples.

Navigate to the java/ directory and build/compile the project:

cd java/
mvn compile

If you have not already done so, please read the top-level README.md to discover how to set up both authentication and the common sample configuration.

All commands should be run from the java/ directory.

Before calling any v1 Merchant API method, you must register the GCP project used to call the APIs. You only need to do this once.

mvn exec:java -Dexec.mainClass="shopping.merchant.samples.accounts.developerregistration.v1.RegisterGcpSample"

For more information, see Register as a developer.

To run a specific sample, use mvn exec:java and specify the main class. For example, to list your products, run:

mvn exec:java -Dexec.mainClass="shopping.merchant.samples.products.v1.ListProductsSample"

By default, alpha samples (such as reviews) are excluded from the build because they require alpha client libraries that are not installed by default.

To compile and run alpha samples:

1. Install the alpha client library on your local machine by following the instructions in the alpha client repository.
2. Build the project using the allow-alpha profile:

mvn compile -Pallow-alpha

Use the same profile when executing alpha samples. For example:

mvn exec:java -Dexec.mainClass="shopping.merchant.samples.reviews.v1alpha.ListProductReviewsSample" -Pallow-alpha

Examine your shell output, be inspired, and start working on an amazing new app!
