Cloud Build client libraries

This page shows how to get started with the Cloud Client Libraries for the Cloud Build API. Client libraries make it easier to access Google Cloud APIs from a supported language. Although you can use Google Cloud APIs directly by making raw requests to the server, client libraries provide simplifications that significantly reduce the amount of code you need to write.

However, we recommend using the older Google API Client Libraries if running on App Engine standard environment . Read more about the Cloud Client Libraries and the older Google API Client Libraries in Client libraries explained .

Install the client library

C++

See Setting up a C++ development environment for details about this client library's requirements and install dependencies.

Go

go get cloud.google.com/go/cloudbuild

For more information, see Setting Up a Go Development Environment .

Java

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

< dependency 
>  
< groupId>com 
 . 
 google 
 . 
 cloud 
< / 
 groupId 
>  
< artifactId>google 
 - 
 cloud 
 - 
 build 
< / 
 artifactId 
>  
< version 
>3.8.0< / 
 version 
>
< / 
 dependency 
>

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

 compile 
  
 group 
 : 
  
 ' 
 com 
 . 
 google 
 . 
 cloud 
 ' 
 , 
  
 name 
 : 
  
 ' 
 google 
 - 
 cloud 
 - 
 build 
 ' 
 , 
  
 version 
 : 
  
 '3.8.0'

For more information, see Setting Up a Java Development Environment .

Node.js

npm install @google-cloud/cloudbuild

For more information, see Setting Up a Node.js Development Environment .

Python

pip install --upgrade google-cloud-build

For more information, see Setting Up a Python Development Environment .

Set up authentication

To authenticate calls to Google Cloud APIs, client libraries support Application Default Credentials (ADC) ; the libraries look for credentials in a set of defined locations and use those credentials to authenticate requests to the API. With ADC, you can make credentials available to your application in a variety of environments, such as local development or production, without needing to modify your application code.

For production environments, the way you set up ADC depends on the service and context. For more information, see Set up Application Default Credentials .

For a local development environment, you can set up ADC with the credentials that are associated with your Google Account:

Install the Google Cloud CLI. After installation, initialize the Google Cloud CLI by running the following command:
```
gcloud  
init
```
If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity .
If you're using a local shell, then create local authentication credentials for your user account:
```
gcloud  
auth  
application-default  
login
```
You don't need to do this if you're using Cloud Shell.

If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity .

A sign-in screen appears. After you sign in, your credentials are stored in the local credential file used by ADC .

Use the client library

The following example shows how to use the client library.
