Examples for gcloud-java (Java idiomatic client for Google Cloud Platform services).

If you are using Maven, add this to your pom.xml file

<dependency>
  <groupId>com.google.gcloud</groupId>
  <artifactId>gcloud-java-examples</artifactId>
  <version>0.1.1</version>
</dependency>

If you are using Gradle, add this to your dependencies

compile 'com.google.gcloud:gcloud-java-examples:0.1.1'

If you are using SBT, add this to your dependencies

libraryDependencies += "com.google.gcloud" % "gcloud-java-examples" % "0.1.1"

To run examples from your command line:

1. Login using gcloud SDK (gcloud auth login in command line)

2. Set your current project using gcloud config set project PROJECT_ID. This step is not necessary for ResourceManagerExample.

3. Compile using Maven (mvn compile in command line from your base project directory)

4. Run an example using Maven from command line.

Here's an example run of BigQueryExample.

Before running the example, go to the Google Developers Console to ensure that BigQuery API is enabled. You can upload a CSV file my_csv_file to the my_bucket bucket (replace my_csv_file and my_bucket with actual file and bucket names) using the GCS web browser. The CSV file will be used to load data into a BigQuery table and should look something like:

value1
value2
value3

Then you are ready to run the following example:

$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.BigQueryExample" -Dexec.args="create dataset new_dataset_id"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.BigQueryExample" -Dexec.args="create table new_dataset_id new_table_id field_name:string"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.BigQueryExample" -Dexec.args="list tables new_dataset_id"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.BigQueryExample" -Dexec.args="load new_dataset_id new_table_id CSV gs://my_bucket/my_csv_file"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.BigQueryExample" -Dexec.args="query 'select * from new_dataset_id.new_table_id'"

Here's an example run of DatastoreExample.

Note that you have to enable the Google Cloud Datastore API on the Google Developers Console before running the following commands.

$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.DatastoreExample" -Dexec.args="my_name add my\ comment"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.DatastoreExample" -Dexec.args="my_name display"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.DatastoreExample" -Dexec.args="my_name delete"

Here's an example run of ResourceManagerExample.

Be sure to change the placeholder project ID "my-project-id" with your own globally unique project ID.

$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.ResourceManagerExample" -Dexec.args="create my-project-id"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.ResourceManagerExample" -Dexec.args="list"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.ResourceManagerExample" -Dexec.args="get my-project-id"

Here's an example run of StorageExample.

Before running the example, go to the Google Developers Console to ensure that Google Cloud Storage API is enabled and that you have a bucket. Also ensure that you have a test file (test.txt is chosen here) to upload to Cloud Storage stored locally on your machine.

$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.StorageExample" -Dexec.args="upload /path/to/test.txt <bucket_name>"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.StorageExample" -Dexec.args="list <bucket_name>"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.StorageExample" -Dexec.args="download <bucket_name> test.txt"
$mvn exec:java -Dexec.mainClass="com.google.gcloud.examples.StorageExample" -Dexec.args="delete <bucket_name> test.txt"
