Bot Framework for Java

This repository contains code for the Java version (currently in preview) of the Microsoft Bot Framework SDK, which is part of the Microsoft Bot Framework - a comprehensive framework for building enterprise-grade conversational AI experiences.

This SDK enables developers to model conversation and build sophisticated bot applications using JavaScript. SDKs for .NET, Python and JavaScript are also available.

To get started building bots using the SDK, see the Azure Bot Service Documentation. If you are an existing user, then you can also find out what's new with Bot Framework.

Getting Started

To get started building bots using the SDK, see the Azure Bot Service Documentation.

The Bot Framework Samples includes a rich set of samples repository.

If you want to debug an issue, would like to contribute, or understand how the Bot Builder SDK works, instructions for building and testing the SDK are below.



Clone a copy of the repo:

git clone

Change to the SDK's directory:

cd botbuilder-java

Now at the command prompt type:

mvn clean install

Build and test locally

Any IDE that can import and work with Maven projects should work. As a matter of practice we use the command line to perform Maven builds. If your IDE can be configured to defer build and run to Maven it should also work.

Linting rules

This project uses linting rules to enforce code standardization. These rules are specified in the file bot-checkstyle.xml with CheckStyle and are hooked to Maven's build cycle.

INFO: Since the CheckStyle and PMD plugins are hooked into the build cycle, this makes the build fail in cases where there are linting warnings in the project files. Errors will be in the file ./target/checkstyle-result.xml and ./target/pmd.xml.

CheckStyle is available in different flavours:

INFO: Be sure to configure your IDE to use the file bot-checkstyle.xml instead of the default rules.
