Getting Started with Datastore Samples

Running a sample using Cloud Shell

The Google Cloud Shell has application default credentials from its compute instance which will allow you to run samples without having to obtain GOOGLE_APPLICATION_CREDENTIALS. Go to the Datastore Client Readme to run each sample in the Cloud Shell.

Running a sample at the command line

First set up the GOOGLE_CLOUD_PROJECT environment variable.
Obtain authentication credentials.

Create local credentials by running the following command and following the oauth2 flow (read more about the command here):
```
 gcloud auth application-default login
```
Or manually set the GOOGLE_APPLICATION_CREDENTIALS environment variable to point to a service account key JSON file path.

Learn more at Setting Up Authentication for Server to Server Production Applications.

Now you can run a sample:

cd samples/snippets - all samples are located in the java-datastore/samples/snippets directory.
mvn compile exec:java -Dexec.mainClass="com.google.datastore.snippets.TaskList" - this runs the TaskList sample.
