If you want to build the project, no prerequisites are required. Run ./gradlew build from the checkout directory. This will download the required mbeddr platform language library from the itemis Nexus repository.
When the build finishes, you can open the project in MPS in <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 the mbeddr documentation).
The latest supported MPS version is master, plus the two previous versions on maintenance branches.
We take care of porting changes done in older supported MPS versions to the newer ones. For details, see the wiki.

When you open a PR, the build on TeamCity needs to be approved by a colleague at itemis, and a PR review is necessary. If this doesn't happen, please ask in the Slack channel. Often, builds fail at the following step: Check for dirty files.
If that happens, some migrations were not executed in the project. Run ./gradlew migrate remigrate or gradlew.bat migrate remigrate on the command line to execute them and commit the changes. You can also copy the diff from the build log and apply it with git apply as a patch. You need to strip the line numbers, though:
- Mac:
pbpaste | sed 's/^.\{13\}//' | git apply - Windows Powershell:
Get-Clipboard | ForEach-Object { $_ -replace '^.{13}', '' } | git apply - Linux solution 1:
xclip -o | sed 's/^.\{13\}//' | git apply - Linux solution 2:
xsel --clipboard --output | sed 's/^.\{13\}//' | git apply
The Renovate bot updates the dependencies automatically for the master branch or optionally other branches and creates PRs for those changes. The configuration can be found at renovate.json5. The documentation for the configuration can be found at https://docs.renovatebot.com/configuration-options/.
