Temporal is a Workflow-as-Code platform for building and operating resilient applications using developer-friendly primitives, instead of constantly fighting your infrastructure.

The Java SDK is the framework for authoring Workflows and Activities in Java. (For other languages, see Temporal SDKs.)

Java SDK:

• Java SDK documentation
• Javadoc API reference
• Sample applications

Temporal in general:

• Temporal docs
• Install Temporal Server
• Temporal CLI

Find the latest release of the Temporal Java SDK at maven central.

Add temporal-sdk as a dependency to your pom.xml:

<dependency>
  <groupId>io.temporal</groupId>
  <artifactId>temporal-sdk</artifactId>
  <version>N.N.N</version>
</dependency>

or to build.gradle:

compile group: 'io.temporal', name: 'temporal-sdk', version: 'N.N.N'

Due to issues with default hostname resolution (see this StackOverflow question for more details), macOS Users may see gRPC DEADLINE_EXCEEDED errors and other slowdowns when running the SDK.

To solve the problem add the following entries to your /etc/hosts file (where my-macbook is your hostname):

127.0.0.1   my-macbook
::1         my-macbook
