[//]: # (API_TABLE_END)

If the service is not listed, [google-api-java-client][google-api-java-client-services] interfaces with additional Google Cloud APIs using a legacy REST interface.

*When building Java applications, preference should be given to the libraries listed in the table.*



## Specifying a Project ID

Most `google-cloud` libraries require a project ID.  There are multiple ways to specify this project ID.

1. When using `google-cloud` libraries from within Compute/App Engine, there's no need to specify a project ID.  It is automatically inferred from the production environment.
2. When using `google-cloud` elsewhere, you can do one of the following:
* Supply the project ID when building the service options.  For example, to use Datastore from a project with ID "PROJECT_ID", you can write:

  ```java
  Datastore datastore = DatastoreOptions.newBuilder().setProjectId("PROJECT_ID").build().getService();
  ```
* Specify the environment variable `GOOGLE_CLOUD_PROJECT` to be your desired project ID.
* Set the project ID using the [Google Cloud SDK](https://cloud.google.com/sdk/?hl=en).  To use the SDK, [download the SDK](https://cloud.google.com/sdk/?hl=en) if you haven't already, and set the project ID from the command line.  For example:

  ```
  gcloud config set project PROJECT_ID
  ```

`google-cloud` determines the project ID from the following sources in the listed order, stopping once it finds a value:

1. The project ID supplied when building the service options
2. Project ID specified by the environment variable `GOOGLE_CLOUD_PROJECT`
3. The App Engine / Compute Engine project ID
4. The project ID specified in the JSON credentials file pointed by the `GOOGLE_APPLICATION_CREDENTIALS` environment variable
5. The Google Cloud SDK project ID

In cases where the library may expect a project ID explicitly, we provide a helper that can provide the inferred project ID:
   ```java
     import com.google.cloud.ServiceOptions;
     ...
     String projectId = ServiceOptions.getDefaultProjectId();
   ```

## Authentication

`google-cloud-java` uses
[https://github.com/googleapis/google-auth-library-java](https://github.com/googleapis/google-auth-library-java)
to authenticate requests. `google-auth-library-java` supports a wide range of authentication types;
see the project's [README](https://github.com/google/google-auth-library-java/blob/main/README.md)
and [javadoc](https://cloud.google.com/java/docs/reference/google-auth-library/latest/overview) for more
details.

### Google Cloud Platform environment

When using Google Cloud libraries from a Google Cloud Platform environment such as Compute Engine,
Kubernetes Engine, or App Engine, no additional authentication steps are necessary.

For example:

```java
Storage storage = StorageOptions.getDefaultInstance().getService();
```

or:

```java
CloudTasksClient cloudTasksClient = CloudTasksClient.create();
```

### Other environments

#### Using a service account (recommended)

1. [Generate a JSON service account key](https://cloud.google.com/storage/docs/authentication?hl=en#service_accounts).

2. After downloading that key, you must do one of the following:
    * Define the environment variable GOOGLE_APPLICATION_CREDENTIALS to be the location of the key.
      For example:
    ```bash
    export GOOGLE_APPLICATION_CREDENTIALS=/path/to/my/key.json
    ```
    * Supply the JSON credentials file when building the service options. For example, this Storage
      object has the necessary permissions to interact with your Google Cloud Storage data:
    ```java
    Storage storage = StorageOptions.newBuilder()
        .setCredentials(ServiceAccountCredentials.fromStream(new FileInputStream("/path/to/my/key.json")))
        .build()
        .getService();
    ```

#### Local development/testing

If running locally for development/testing, you can use the [Google Cloud SDK](https://cloud.google.com/sdk/).
Create Application Default Credentials with `gcloud auth application-default login`, and then
`google-cloud` will automatically detect such credentials.

#### Existing OAuth2 access token

If you already have an OAuth2 access token, you can use it to authenticate (notice that in this case, the
access token will not be automatically refreshed):

```java
Credentials credentials = GoogleCredentials.create(new AccessToken(accessToken, expirationTime));
Storage storage = StorageOptions.newBuilder()
    .setCredentials(credentials)
    .build()
    .getService();
```

or:

```java
Credentials credentials = GoogleCredentials.create(new AccessToken(accessToken, expirationTime));
CloudTasksSettings cloudTasksSettings = CloudTasksSettings.newBuilder()
    .setCredentialProvider(FixedCredentialsProvider.create(credentials))
    .build();
CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
```

### Application Default Credentials

If no credentials are provided, `google-cloud` will attempt to detect them from the environment
using `GoogleCredentials.getApplicationDefault()` which will search for Application Default
Credentials in the following locations (in order):

1. The credentials file pointed to by the `GOOGLE_APPLICATION_CREDENTIALS` environment variable
2. Credentials provided by the Google Cloud SDK `gcloud auth application-default login` command
3. Google App Engine built-in credentials
4. Google Cloud Shell built-in credentials
5. Google Compute Engine built-in credentials

## Troubleshooting

To get help, follow the instructions in the [Troubleshooting document](https://github.com/googleapis/google-cloud-java/blob/main/TROUBLESHOOTING.md).

## Configuring a Proxy

Google Cloud client libraries use HTTPS and gRPC in underlying communication
with the services.
In both protocols, you can configure a proxy using `https.proxyHost`
and (optional) `https.proxyPort` properties.

### gRPC Custom Proxy Configuration

For a more custom proxy with gRPC, you will need supply a `ProxyDetector` to
the `ManagedChannelBuilder`:

```java
import com.google.api.core.ApiFunction;
import com.google.api.gax.rpc.TransportChannelProvider;
import com.google.cloud.tasks.v2.CloudTasksClient;
import com.google.cloud.tasks.v2.CloudTasksSettings;
import com.google.cloud.tasks.v2.stub.CloudTasksStubSettings;
import io.grpc.HttpConnectProxiedSocketAddress;
import io.grpc.ManagedChannelBuilder;
import io.grpc.ProxiedSocketAddress;
import io.grpc.ProxyDetector;

import javax.annotation.Nullable;
import java.io.IOException;
import java.net.InetSocketAddress;
import java.net.SocketAddress;

public CloudTasksClient getService() throws IOException {
  TransportChannelProvider transportChannelProvider =
      CloudTasksStubSettings.defaultGrpcTransportProviderBuilder()
          .setChannelConfigurator(
              new ApiFunction<ManagedChannelBuilder, ManagedChannelBuilder>() {
                @Override
                public ManagedChannelBuilder apply(ManagedChannelBuilder managedChannelBuilder) {
                  return managedChannelBuilder.proxyDetector(
                      new ProxyDetector() {
                        @Nullable
                        @Override
                        public ProxiedSocketAddress proxyFor(SocketAddress socketAddress)
                            throws IOException {
                          return HttpConnectProxiedSocketAddress.newBuilder()
                              .setUsername(PROXY_USERNAME)
                              .setPassword(PROXY_PASSWORD)
                              .setProxyAddress(new InetSocketAddress(PROXY_HOST, PROXY_PORT))
                              .setTargetAddress((InetSocketAddress) socketAddress)
                              .build();
                        }
                      });
                }
              })
          .build();
  CloudTasksSettings cloudTasksSettings =
      CloudTasksSettings.newBuilder()
          .setTransportChannelProvider(transportChannelProvider)
          .build();
  return CloudTasksClient.create(cloudTasksSettings);
}
```

## Long Running Operations

Long running operations (LROs) are often used for API calls that are expected to
take a long time to complete (e.g. provisioning a GCE instance or a Dataflow pipeline).
The initial API call creates an "operation" on the server and returns an operation ID
to track its progress.

Our generated gRPC clients provide a nice interface for starting the operation and
then waiting for the operation to complete. This is accomplished by returning an
[`OperationFuture`](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.longrunning.OperationFuture).
When you call `get()` on the `OperationFuture` we poll the operation endpoint to
check on the operation. These polling operations have a default timeout that
varies from service to service and will throw a `java.util.concurrent.CancellationException`
with the message: `Task was cancelled.` after that timeout has been reached.

### Configuring LRO Timeouts

```java
ClusterControllerSettings.Builder settingsBuilder = ClusterControllerSettings.newBuilder();
TimedRetryAlgorithm timedRetryAlgorithm = OperationTimedPollAlgorithm.create(
		RetrySettings.newBuilder()
				.setInitialRetryDelay(Duration.ofMillis(500L))
				.setRetryDelayMultiplier(1.5)
				.setMaxRetryDelay(Duration.ofMillis(5000L))
				.setInitialRpcTimeout(Duration.ZERO) // ignored
				.setRpcTimeoutMultiplier(1.0) // ignored
				.setMaxRpcTimeout(Duration.ZERO) // ignored
				.setTotalTimeout(Duration.ofHours(24L))	// set polling timeout to 24 hours
				.build());
settingsBuilder.createClusterOperationSettings()
		.setPollingAlgorithm(timedRetryAlgorithm);
ClusterControllerClient clusterControllerClient = ClusterControllerClient.create(settingsBuilder.build());
```

## Managing Dependencies

If you are using more than one Google Cloud client library, we recommend you use one of
our Bill of Material (BOM) artifacts to help manage dependency versions. For more information,
see [Using the Cloud Client Libraries](https://cloud.google.com/java/docs/bom).

## Java Versions

Java 8 or above is required for using the clients in this repository.

## Supported Platforms

Clients in this repository use either HTTP or gRPC for the transport layer. All
HTTP-based clients should work in all environments.

For clients that use gRPC, the supported platforms are constrained by the platforms
that [Forked Tomcat Native](http://netty.io/wiki/forked-tomcat-native.html) supports,
which for architectures means only x86_64, and for operating systems means Mac OS X,
Windows, and Linux. Additionally, gRPC constrains the use of platforms with
threading restrictions.

Thus, the following are not supported:

- Android
    - Consider [Firebase](https://firebase.google.com), which includes many of these APIs.
    - It is possible to use these libraries in many cases, although it is unsupported.
      You can find examples, such as [this one](https://github.com/GoogleCloudPlatform/android-docs-samples/tree/main/speech/SpeechRecognitionClient),
      in this [example repository](https://github.com/GoogleCloudPlatform/android-docs-samples) but consider the risks carefully before using these libraries in an application.
- Raspberry Pi (since it runs on the ARM architecture)
- Google App Engine Standard Java 7

The following environments should work (among others):

- standalone Windows on x86_64
- standalone Mac OS X on x86_64
- standalone Linux on x86_64
- Google Compute Engine (GCE)
- Google Container Engine (GKE)
- Google App Engine Standard Java 8 (GAE Std J8)
- Google App Engine Flex (GAE Flex)
- Alpine Linux (Java 11+)

## Testing

## Versioning

This library follows [Semantic Versioning](http://semver.org/), with some
additional qualifications:

1. Components marked with `@BetaApi` or `@Experimental` are considered to be "0.x"
   features inside a "1.x" library. This means they can change between minor and
   patch releases in incompatible ways. These features should not be used by any
   library "B" that itself has consumers, unless the components of library B that
   use `@BetaApi` features are also marked with `@BetaApi`. Features marked as
   `@BetaApi` are on a path to eventually become "1.x" features with the marker
   removed.

   **Special exception for google-cloud-java**: google-cloud-java is
   allowed to depend on `@BetaApi` features in gax-java without declaring the consuming
   code `@BetaApi`, because gax-java and google-cloud-java move in step
   with each other. For this reason, gax-java should not be used
   independently of google-cloud-java.

1. Components marked with `@InternalApi` are technically public, but only
   because of the limitations of Java's access
   modifiers. For the purposes of semver, they should be considered private.

1. Interfaces marked with `@InternalExtensionOnly` are public, but should only be
   implemented by internal classes. For the purposes of semver, we reserve the right
   to add to these interfaces without default implementations (for Java 7).

Please note these clients are currently under active development. Any release versioned 0.x.y is
subject to backwards incompatible changes at any time.

### Stable

Libraries defined at a Stable quality level are expected to be stable and all updates in the
libraries are guaranteed to be backwards-compatible. Any backwards-incompatible changes will lead
to the major version increment (1.x.y -> 2.0.0).

### Preview

Libraries defined at a Preview quality level are still a work-in-progress and
are more likely to get backwards-incompatible updates. Additionally, it's possible for Preview
libraries to get deprecated and deleted before ever being promoted to Preview or Stable.

## IDE Plugins

If you're using IntelliJ or Eclipse, you can add client libraries to your project using these IDE plugins:
* [Cloud Tools for IntelliJ](https://cloud.google.com/tools/intellij/docs/client-libraries?utm_source=github&utm_medium=google-cloud-java&utm_campaign=ToolsforIntelliJ)
* [Cloud Tools for Eclipse](https://cloud.google.com/eclipse/docs/libraries?utm_source=github&utm_medium=google-cloud-java&utm_campaign=ToolsforEclipse)

Besides adding client libraries, the plugins provide additional functionality, such as service account
key management. Refer to the documentation for each plugin for more details.

These client libraries can be used on App Engine standard for Java 8 runtime and App Engine flexible
(including the Compat runtime).  Most of the libraries do not work on the App Engine standard for Java 7
runtime. However, Datastore, Storage, and Bigquery should work.
