-GeoNetwork is a Java 8 application that runs as a servlet, which means that a Java Development Kit (JDK) must be installed in order to build and run it. You can get a Java 8 JDK from your Linux distribution, [Oracle OpenJDK](http://openjdk.java.net/) or [AdoptOpenJDK](https://adoptopenjdk.net). Please note that the Java 8 [Oracle JDK](http://www.oracle.com/technetwork/java/javase/downloads) is currently only being distributed for testing purposes.

 The following tools are required to be installed to setup a development environment for GeoNetwork:
 
--   **Java 8** - Developing with GeoNetwork requires Java Development Kit (JDK) 1.8.
+-   **Java 11** - Developing with GeoNetwork requires Java Development Kit (JDK) 11.
 -   **Maven** 3.1.0+ - GeoNetwork uses [Maven](http://maven.apache.org/) to manage the build process and the dependencies. Once is installed, you should have the mvn command in your path (on Windows systems, you have to open a shell to check).
 -   **Git** - GeoNetwork source code is stored and versioned in [a Git repository on Github](https://github.com/geonetwork/core-geonetwork). Depending on your operating system a variety of Git clients are available. Please check the Git website for some [alternatives](http://git-scm.com/downloads/guis) and good [documentation](http://git-scm.com/documentation). More documentation can be found on the [Github website](https://help.github.com/).
 -   **Ant** - GeoNetwork uses [Ant](http://ant.apache.org/) to build the installer. Version 1.6.5 works but any other recent version should be OK. Once installed, you should have the Ant command in your path (on Windows systems, you have to open a shell to check).

 GeoNetwork arrives with a default container called Jetty. Jetty is a powerful minimal container implementation. If you need more configuration options consider to use Tomcat. Other containers can be used, but there are not many user experiences. Read more at [Installing from WAR file](../../install-guide/installing-from-war-file.md)
