is there a remote chance to use Gradle Version Catalog with 
@file:DependsOn("...")
? 🙈 scripting would have to know where to look for the TOML file, and it's non-trivial to infer. It could traverse starting from the script's location, up the file tree, until it finds 
gradle/libs.versions.toml
I'm shamelessly ignoring the fact that Kotlin Scripting and Gradle isn't integrated in any way, but I thought I'll ask anyway since the Catalog may be usable as a stand-alone tool?
ah, and IDE support would have to be present here
m
Probably not the answer you're looking for but I think scripting shouldn't aim to support version catalogs if it wants to remain simple.
Generally, I would like 
*.main.kts
to know nothing about Gradle
p
Gradle as a build system - yes, but the version catalog serves having no duplicated version which is appealing in a project where one uses both Gradle and Kotlin scripts
m
If you have Gradle in your project, what do you gain by using scripts compared to a custom 
JavaExec
task where you can control everything?

calling the script directly, like with github-workflows-kt - so simplicity, as you write 🙂
m
Make a shell script that calls 
./gradlew runScript
?
I understand the appeal of adding more features to 
*.main.kts
but this is a dangerous slope IMO
p
Make a shell script that calls 
./gradlew runScript
?
then github-workflows-kt would have to be aware of using this way of running the script
yeah, I understand and agree that the main goal of scripting is simplicity, I just started wondering... 🙂
m
👍 curious to hear what others think.
p
but e.g. support for compiler plugins should probably be added - it's an important part of Kotlin, and simplicity doesn't justify the current feature imparity
m
That doesn't involve Gradle, count me in 😄

Some time ago, I wrote an issue about adding Gradle metadata support to the 
*.main.kts
resolver but I think I changed my mind
Library producers can be maven compatible if they want to (they should)

adding to the version catalog thing: nothing stops me/anyone from writing a piece of validation that would check that the version defined in the version catalog matches the one used in the script. However, I'm not super-enthusiastic to do it, it does feel itchy

I don't think 
.main.kts
should support version catalogs ootb, especially not with a hard-coded Gradle-specific location. Once compiler plugins are possible, maybe you can implement that as compiler plugin. đŸ€·â€â™‚ïž Gradle module metadata support on the other hand would be great. For example when some library has mutliple feature variants, or different variants depending on Java version, or for example a multi-platform Kotlin library.

I think it'd be reasonable if main.kts had some way of declaring a custom dependency resolver service. By default it'd just be the simple Maven resolution, but you could implement your own custom resolution if required.

Is there anything else than the ivy aether resolver used by 
*.main.kts
(that was quite dated from what I remember when I looked at this a long time ago) and the Gradle implementation (that is very tightly ties to the Gradle binary and boderline impossible to use outside of Gradle)
Not saying this isn't a good idea, it'd be great but in practice, it's probably not going to be super used....
Unless of course this creates an opportunity and more folks start implementing new resolvers 🙌
v
*.main.kts
does not use Ivy
👍 1
It uses Aether, the resolution engine that is also part of Maven
👍 1
m
Ah, yes! I remember now. I struggled to find the code for that
I think I ended up on sourceforge at some point?
v
Ah, yeah Aether was dead and with 1.7.20 they switched to 
org.apache.maven.resolver
Which still has aether in the package name, so probably a fork
m
Ah!
Much better.
There's even a GitHub repo 👀 https://github.com/apache/maven-resolver/

p
Is there an analogous resolver lib for Gradle?
m
Nope, I asked some time ago and the answer was that it was probably never going to be done given how tightly integrated it is with the rest of the system
😐 1
v
Well, you can use the whole Gradle distribution. 😄
Or if you are dedicated enough, you could try to refactor out the resolution engine so that it is usable stand-alone and send a PR upstream, hoping they are open for it. đŸ€·â€â™‚ïž
m
That was more or less the plan but I gave up really early 😄
