Getting Started with Google Cloud Authentication

See the documentation for more information about authenticating for Google Cloud APIs.

Quickstart

Install Maven.

Build your project with:

mvn clean package -DskipTests

You can then run a given ClassName via:

mvn exec:java -Dexec.mainClass=com.example.storage.ClassName \
    -DpropertyName=propertyValue \
	-Dexec.args="any arguments to the app"

Listing buckets with default credentials

mvn exec:java -Dexec.mainClass=com.google.cloud.auth.samples.AuthExample

Listing buckets with credentials in json file

mvn exec:java -Dexec.mainClass=com.google.cloud.auth.samples.AuthExample
    -Dexec.args="explicit [path-to-credentials-json]"

Listing buckets while running on a Google Compute Engine instance

mvn exec:java -Dexec.mainClass=com.google.cloud.auth.samples.AuthExample
    -Dexec.args="compute"

Analyze text sentiment using LanguageService API with API key authentication

Create an API key via the Google Cloud console:

Once you have an API key replace it in the main function in ApiKeyAuthExample and run the following command

mvn exec:java -Dexec.mainClass=com.google.cloud.auth.samples.ApiKeyAuthExample

Downscoping with Credential Access Boundaries

The same configuration above applies.

To run the samples for Downscoping with Credential Access Boundaries you must provide both a bucket name and object name under the TODO(developer): in the main method of DownscopingExample.

You can then run DownscopingExample via:

mvn exec:java -Dexec.mainClass=com.google.cloud.auth.samples.DownscopingExample

Tests

Run all tests:

   mvn clean verify
