MPS Extensions

official JetBrains project

The MPS extensions aim to ease language development within MPS. They are maintained by itemis, JetBrains, and the open source community, and the development is closely aligned with the development of MPS.

Maven Dependencies

To use MPS Extensions in your project, add one of the following dependencies to your Maven or Gradle build script:


MPS version nexus status


Run the following commands to build the project:

./gradlew # Mac and Linux
gradlew.bat # Windows

This will download the required MPS version, so you need to be online when executing the build for the first time (later on, the downloaded artifacts will be cached).

The default task does not run the tests as part of the build. Execute the following command to run the tests:

./gradlew run_tests # Mac and Linux
gradlew.bat run_tests # Windows

See the building page of the documentation for more details.


If you would like more information on the individual extensions, please see our documentation. The documentation's source is located in this repository's docs folder if you would like to contribute to it. To preview the documentation, run the following command:
