Building¶

The MPS extensions are built using Gradle. To build the source code, all you need on the machine is a Java JDK. Starting from MPS-extensions 2022.2, JDK 17 is required. For older versions you need JDK 11. For ancient maintenance versions you only need JDK 8. If you want to contribute to MPS-extensions, you need MPS. The current used MPS version can be found in the build.gradle file under the value ext.mpsMajor.

To build the project, run:

1 2	`./gradlew # Mac and Linux gradlew.bat # Windows`

This will fetch the required MPS version from the internet, so you need to be online when first execute the build. The default task is build_languages.

The default task doesn’t run the test when building if you want to execute the tests then run:

1 2	`./gradlew run_tests # Mac and Linux gradlew.bat run_tests # Windows`

The documentation is built using Material for MkDocs and Python 3. It can be previewed by running:

1 2	`./gradlew previewDocs # Mac and Linux gradlew.bat previewDocs # Windows`
