To setup Apache Ignite project in Intellij IDEA you need to accomplish the following two steps.

• Checkout Apache Ignite source
  • Contributors need to checkout sources of your fork of https://github.com/apache/ignite (or https://github.com/apache/ignite-3 for Ignite 3 project)
  • Committers have an option to checkout ASF repo directly https://git-wip-us.apache.org/repos/asf/ignite (or https://git-wip-us.apache.org/repos/asf/ignite-3 for Ignite 3 project)
• Open Intellij IDEA and create a new project by referring to ignite_folder/pom.xml file

The IDEA will import all the required modules automatically.
