Upgrade to GraalVM JDK 21. ``` > java -version openjdk version "21" 2023-09-19 OpenJDK Runtime Environment GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15) OpenJDK 64-Bit Server VM GraalVM CE 21+35.1 (build 21+35-jvmci-23.1-b15, mixed mode, sharing) ``` With SDKMan, download with `sdk install java 21-graalce`. # Important Notes - After this PR, one can theoretically run enso with any JRE with version at least 21. - Removed `sbt bootstrap` hack and all the other build time related hacks related to the handling of GraalVM distribution. - `project-manager` remains backward compatible - it can open older engines with runtimes. New engines now do no longer require a separate runtime to be downloaded. - sbt does not support compilation of `module-info.java` files in mixed projects - https://github.com/sbt/sbt/issues/3368 - Which means that we can have `module-info.java` files only for Java-only projects. - Anyway, we need just a single `module-info.class` in the resulting `runtime.jar` fat jar. - `runtime.jar` is assembled in `runtime-with-instruments` with a custom merge strategy (`sbt-assembly` plugin). Caching is disabled for custom merge strategies, which means that re-assembly of `runtime.jar` will be more frequent. - Engine distribution contains multiple JAR archives (modules) in `component` directory, along with `runner/runner.jar` that is hidden inside a nested directory. - The new entry point to the engine runner is [EngineRunnerBootLoader](https://github.com/enso-org/enso/pull/7991/files#diff-9ab172d0566c18456472aeb95c4345f47e2db3965e77e29c11694d3a9333a2aa) that contains a custom ClassLoader - to make sure that everything that does not have to be loaded from a module is loaded from `runner.jar`, which is not a module. - The new command line for launching the engine runner is in [distribution/bin/enso](https://github.com/enso-org/enso/pull/7991/files#diff-0b66983403b2c329febc7381cd23d45871d4d555ce98dd040d4d1e879c8f3725) - [Newest version of Frgaal](https://repo1.maven.org/maven2/org/frgaal/compiler/20.0.1/) (20.0.1) does not recognize `--source 21` option, only `--source 20`. |

Enso CLI
Actionables for this file:
- This is just a draft of the file that will be included inside the launcher distribution. It should be completed when the launcher is implemented.
Installation
The Enso distribution is portable, you can put this directory wherever you want
on your system. For example you can put it at ~/.enso.
It is a good idea to add the bin directory to your system PATH so that you
can run Enso just by typing enso in any directory.
Usage
Actionables for this section:
- Fill in examples showing how to use the launcher.
Distribution structure
Actionables for this section:
- This should explain the structure of enso distribution directory, based on the documentation.
