Upgrading GraalVM

After upgrading the project to a newer version of GraalVM, all developers must take the following actions to be able to continue development after the upgrade:

1. Download the new JVM version and set it as the default for the project. If you use IntelliJ, you will also need to update the JVM used for the project in the project settings.
2. Re-run sbt bootstrap to get the updated Truffle JAR (if there are issues updating, removing engine/runtime/build-cache directory may help).
3. Do a full clean (it may not always be required, but not doing it often leads to problems so it is much safer to do it) by running enso/clean.
4. To be able to build or run tests for the launcher project, Native Image for the new GraalVM version has to be installed, as it is not included by default. This can be done with <path-to-graal-home>/bin/gu install native-image.
   • If there are problems building the Native Image, removing engine/launcher/build-cache (which contains the downloaded musl package) may help.
