[core] Scripting engine missing modules when using native image

[Sculas]

When trying to run the deobf script, I get this error:

WARN : Script execution issue: Using new faster version of JAR FS: it should make your build faster, but the new implementation is experimental
ERROR: Script execution error: Module kotlin.stdlib cannot be found in the module graph
ERROR: Script execution error: Module kotlin.script.runtime cannot be found in the module graph
ERROR: Script execution error: Module kotlin.reflect cannot be found in the module graph
ERROR: Script execution failed: deobf

If I then click on the script in the GUI and click Run, things get even worse:

Weirdly enough, I'm able to run scripts fine when running JADX in the IDE, but not when running it standalone. I'm having this issue with my own JADX scripts as well, but this applies to any script as far as I'm aware.

but not when running it standalone

How do you build this version?
Because I can't reproduce your issue using unstable build nor with version built by ./gradlew dist.

I just downloaded this build: https://nightly.link/skylot/jadx/workflows/build-artifacts/master/jadx-gui-1.4.7.146-5aaceee9-no-jre-win.exe
.. downloaded the deobf.jadx.kts script from GitHub and was able to reproduce it immediately.

I just realized that in all my testing, everytime I ran it standalone, it was using the native image. In the IDE, it just ran the main function. It could also very well be that scripting just doesn't work in the native image. If still needed, I'll test that in 30 mins.

Oh, thanks! Looks like issue in building fat jar for that artifact, I will investigate this.
As workaround, for now, you can try using zip bundle like this.

Issue caused by ShadowJar removing module-info.class files (check GradleUp/shadow#710) so Kotlin script compiler was unable to find modules while building new execution classpath. Also I am not sure if it is even possible to have several modules in one jar file.
As a workaround, I set Kotlin compiler to JDK release 8, so it will not use modules anymore 🤣
