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

Build configuration
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'
macOS Users
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
