Integrating IntelliJ IDEA
This article is part of the Getting Started Section. It describes how to run XPath/XQuery code from within the IntelliJ IDEA IDE. There are currently two XQuery plugins for IntelliJ IDEA on the market:
- The xquery-intellij-plugin by Reece H. Dunn.
- The XQuery Support + MarkLogic Debugger plugin by Grzegorz Ligas.
- Note: BaseX itself is a highly compliant XQuery 3.1 processor. We strongly encourage you to use the XML editor integrated into the BaseX GUI to edit and query your XML data!
Preparations
The following steps apply to all operating systems and both plugins:
- Install either version of IntelliJ IDEA: the Community or Ultimate edition.
- Download your favorite BaseX distribution (JAR, ZIP, EXE).
- Start BaseX (see Startup).
- Create a BaseX database (see Databases).

- In the Settings/Preferences window, expand the Languages & Frameworks item and select XQuery.
- Make the choices for your system from the dropdown boxes, e.g.:
Implementation = BaseX
Implementation version = BaseX 9.1
Default XQuery version = XQuery 3.1
Dialect for XQuery 3.0 = BaseX
Dialect for XQuery 3.1 = BaseX
- Click Apply to store your XQuery settings and then OK to exit the dialog.
