• Client Library Documentation

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

<dependencyManagement>  <dependencies>    <dependency>      <groupId>com.google.cloud</groupId>      <artifactId>libraries-bom</artifactId>      <version>26.65.0</version>      <type>pom</type>      <scope>import</scope>    </dependency>  </dependencies></dependencyManagement><dependencies>  <dependency>    <groupId>com.google.cloud</groupId>    <artifactId>google-cloud-firestore</artifactId>  </dependency>

If you are using Maven without the BOM, add this to your dependencies:

<dependency>  <groupId>com.google.cloud</groupId>  <artifactId>google-cloud-firestore</artifactId>  <version>3.31.9</version></dependency>

If you are using Gradle 5.x or later, add this to your dependencies:

implementation platform('com.google.cloud:libraries-bom:26.72.0')implementation'com.google.cloud:google-cloud-firestore'

If you are using Gradle without BOM, add this to your dependencies:

implementation'com.google.cloud:google-cloud-firestore:3.34.0'

If you are using SBT, add this to your dependencies:

libraryDependencies+="com.google.cloud"%"google-cloud-firestore"%"3.34.0"

See theAuthentication section in the base directory's README.

The client application making API calls must be grantedauthorization scopes required for the desired Cloud Firestore APIs, and the authenticated principal must have theIAM role(s) required to access GCP resources using the Cloud Firestore API calls.

You will need aGoogle Cloud Platform Console project with the Cloud FirestoreAPI enabled.You will need toenable billing to use Google Cloud Firestore.Follow these instructions to get your project set up. You will also need to set up the local development environment byinstalling the Google Cloud Command Line Interface and running the following commands in command line:gcloud auth login andgcloud config set project [YOUR PROJECT ID].

You'll need to obtain thegoogle-cloud-firestore library. See theQuickstart sectionto addgoogle-cloud-firestore as a dependency in your code.

Cloud Firestore is a fully-managed NoSQL document database for mobile, web, and server development from Firebase and Google Cloud Platform. It's backed by a multi-region replicated database that ensures once data is committed, it's durable even in the face of unexpected disasters. Not only that, but despite being a distributed database, it's also strongly consistent and offers seamless integration with other Firebase and Google Cloud Platform products, including Google Cloud Functions.

Cloud Firestore uses gRPC for the transport layer.

Java 8 or above is required for using this client.

Google's Java client libraries,Google Cloud Client LibrariesandGoogle Cloud API Libraries,follow theOracle Java SE support roadmap(see the Oracle Java SE Product Releases section).

In general, new feature development occurs with support for the lowest JavaLTS version covered by Oracle's Premier Support (which typically lasts 5 yearsfrom initial General Availability). If the minimum required JVM for a givenlibrary is changed, it is accompanied by asemver major release.

Java 11 and (in September 2021) Java 17 are the best choices for newdevelopment.

Google tests its client libraries with all current LTS versions covered byOracle's Extended Support (which typically lasts 8 years from initialGeneral Availability).

Google's client libraries support legacy versions of Java runtimes with longterm stable libraries that don't receive feature updates on a best efforts basisas it may not be possible to backport all patches.

Google provides updates on a best efforts basis to apps that continue to useJava 7, though apps might need to upgrade to current versions of the librarythat supports their JVM.

The latest versions and the supported Java versions are identified onthe individual GitHub repositorygithub.com/GoogleAPIs/java-SERVICENAMEand ongoogle-cloud-java.

This library followsSemantic Versioning.
