Getting Started

In order to use this library, you first need to go through the following steps:

Install a JDK (Java Development Kit)

Use the Google Cloud Core for Java

To ensure that your project uses compatible versions of the libraries and their component artifacts, import com.google.cloud:libraries-bom and use the BOM to specify dependency versions. Be sure to remove any versions that you set previously. For more information about BOMs, see Google Cloud Platform Libraries BOM.

Maven

Import the BOM in the dependencyManagement section of your pom.xml file. Include specific artifacts you depend on in the dependencies section, but don't specify the artifacts' versions in the dependencies section.

The example below demonstrates how you would import the BOM and include the google-cloud-core artifact.

<dependencyManagement>
 <dependencies>
   <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>  26.32.0</version>
      <type>pom</type>
      <scope>import</scope>
   </dependency>
 </dependencies>
</dependencyManagement>

<dependencies>
 <dependency>
   <groupId>com.google.cloud</groupId>
   <artifactId>google-cloud-core</artifactId>
 </dependency>
</dependencies>

Gradle

BOMs are supported by default in Gradle 5.x or later. Add a platform dependency on com.google.cloud:libraries-bom and remove the version from the dependency declarations in the artifact's build.gradle file.

The example below demonstrates how you would import the BOM and include the google-cloud-core artifact.

implementation platform('com.google.cloud:libraries-bom:  26.32.0')
implementation 'com.google.cloud:google-cloud-core'

The platform and enforcedPlatform keywords supply dependency versions declared in a BOM. The enforcedPlatform keyword enforces the dependency versions declared in the BOM and thus overrides what you specified.

For more details of the platform and enforcedPlatform keywords Gradle 5.x or higher, see Gradle: Importing Maven BOMs.

If you're using Gradle 4.6 or later, add enableFeaturePreview('IMPROVED_POM_SUPPORT') to your settings.gradle file. For details, see Gradle 4.6 Release Notes: BOM import. Versions of Gradle earlier than 4.6 don't support BOMs.

SBT

SBT doesn't support BOMs. You can find recommended versions of libraries from a particular BOM version on the dashboard and set the versions manually. To use the latest version of this library, add this to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-core" % "2.32.0"
