Java Slack SDK

The Java Slack SDK supports the Slack platform in a Java idiomatic way. Developers can use it in any JVM language including Kotlin, Groovy, and Scala.

Within these docs, there are two different modules:

  • Bolt for Java Guides, which is a framework with a simplified API that helps write Slack apps in Java.
  • Java SDK Guides, for when you need a more customized approach to building a Slack app in Java using the Slack API client.

Requirements​

The Java Slack SDK supports OpenJDK 8 and higher LTS versions.

Users can expect every patch release has been done after verifying functionality by running the basic CI builds with all LTS versions and all the unit tests have passed on at least the latest LTS version. We don't run comprehensive verifications with all OpenJDK distributions, but it should work with all of them.
