Pulumi supports writing your infrastructure as code using the Java language. Java 11 or later is required. We support running Maven Pulumi programs, Gradle Pulumi programs, and Pulumi programs packaged as JAR files.


Install Java 11 or later and Apache Maven 3.5 or later.

Getting Started

The fastest way to get up and running is to choose from one of the following Getting Started guides:

Google Cloud


The getting started guides shown above will help you write a Pulumi Java program via tutorial, but this section describes starting a basic project that you can start to explore with.

From an empty directory, create a new project:

$ mkdir myproject && cd myproject
$ pulumi new java

This will create a maven project with a pom.xml and a Pulumi.yaml project file containing some minimal metadata about your project (including a name and description which you may wish to change) and an file in the src/main/java/myproject directory containing your program.

To deploy your infrastructure, run pulumi up and Pulumi will build your app using maven (gradle is also supported) and perform the operations needed to deploy the infrastructure you have declared.

To destroy your infrastructure, run pulumi destroy and Pulumi will terminate the resources that you’ve declared.

This java template is cloud agnostic, and you will need to install additional Java modules for the cloud provider of your choice. Additional templates are available that do this for you:

  • pulumi new aws-java: creates a starter AWS Java project
  • pulumi new azure-java: creates a starter Azure Java project
  • pulumi new gcp-java: creates a starter Google Cloud Java project


In your main method, you will want to call and pass it a method to run that will construct the resources that you’d like to deploy.

package main;

import com.pulumi.Pulumi;

public class Main {
    public static void main(String[] args) {;
    public static void stack(Context ctx) {
        // construct your resources here

You can also use lambda expressions like such:

public static void main(String[] args) { -> {
        // construct your resources here

Datasource Methods

In order to get information from cloud providers, there are classes that allow you to query cloud services for data. They are named using the convention com.pulumi.providername.servicename.[Servicename]Functions and return a java.util.concurrent.CompletableFuture<T>.

Pulumi Java implementation details

The Java Pulumi SDK is available to Go/Java developers in source form on GitHub.

Plugin Acquisition

Pulumi will try to auto-detect which plugins your program is using by analyzing your Java project dependencies and then auto-install them. For example, if a program references it will automatically issue the equivalent of $ pulumi plugin install resource aws.

Running Pulumi with Maven and Gradle

To support running a Pulumi program with Maven, we use the exec:java target. This requires adding the mainClass property to pom.xml


To support running a Pulumi program with Gradle, we use the run target. To support plugin resolution and running a Pulumi program in Gradle we check if the mainClass property is set. If it’s set, we’re in plugin resolution. Otherwise, we interpret it as we’re running a Pulumi program.

application {
    mainClass = project.hasProperty("mainClass")
            ? project.getProperty("mainClass")
            : 'myproject.App'

Pulumi Programming Model

The Pulumi programming model defines the core concepts you will use when creating infrastructure as code programs using Pulumi. Architecture & Concepts describes these concepts with examples available in Java. These concepts are made available to you in the Pulumi SDK.

The Pulumi programming model includes a core concept of Output values, which are used to track how outputs of one resource flow in as inputs to another resource to resolve dependencies. This concept is important to understand when getting started with Pulumi, and the Inputs and Outputs documentation is recommended to get a feel for how to work with this core part of Pulumi in common cases.

Unlike other Pulumi languages, Pulumi Java does not have a dedicated Input<T> = T | Output<T> type. Instead, when constructing resource arguments, builders have overloads that accept both a T and an Output<T> value.
