Build instructions

Using Gradle

If you just want to build the project, no prerequisites are required. Just run ./gradlew build from the checkout directory. This will download required version of the mbeddr platform language library from the itemis Nexus repository. When the build has finished, you can open the project in MPS from the folder <iets3.opensource>/code/languages/org.iets3.opensource

To publish this project's artifacts to the Maven local repository run ./gradlew publishToMavenLocal.

If you want to use a custom version of mbeddr with Gradle, publish its artifacts to the local Maven repository (consult mbeddr documentation).

Supported MPS versions

In general, we support the latest MPS version on master plus the three previous versions on maintenance branches.

What does support mean in this case?

We take care of porting changes done in older supported MPS versions to the newer ones. For details see wiki.

What MPS versions are currently supported?

Opening the project in MPS

Open the folder [ROOT]/code/languages/org.iets3.opensource in MPS where ROOT is the root folder of this project.

Project Structure

The project is separated into the following virtual packages:

_build

Name Description
build-allScripts.xml This ant script generates the overall build script that also contains the script for running the tests from the command line.
prebuild.xml This ant script contains the analysis language, core base, and expressions base.
build-languages.xml This ant script contains all languages and generates the finished zip file.
build-distro.xml This ant script combines the files from the mbeddr platform with the files from the previous script.
build-tests.xml This ant script contains all the test languages and solutions and also runs the KernelF generated tests as part of the build. This is achieved by including an instance of RunKernelFGeneratedTests.
