@rubin55 the package is called scala3, scala-dotty is just some backward compatible symlinks which you don't need to install - i reverted to an old PKGBUILD and bumped the version to fix the error you had

yes, they replaced the release after i deployed it, I did make note of their error with the package not following the standard root directory inclusion

Hi, I see you updated the package to 3.6.2, and also the sha256sum, but, I'm getting another sum for the download: 690f278f88ff8465dd2e8cd314d6c507ad79fef9533e89051f858c8192b7856d; did upstream change the package? Or is something nevarious going on?

Secondly, I noticed you download the file now named as test; this is quite ambiguous as a source name :-).

Finally, did you consider changing the package name to scala3? I think dotty is not really a great name ever since the stable release of Scala version 3.x.

I also noticed that they changed the tar.gz layout again upstream. Here's a diff of the fixes:

@rubin55 thanks for the help, updated with your suggestion - let me know if any issues

@envolution there is one change missing (see upstream issue) that will make everything work again - the maven2 directory is erronuously not added to the package:

Looking at the PKGBUILD now, I do think it is better to copy the entire archive output to /usr/share/scala3 instead of cherry-picking; this would avoid issues with future releases changing the layout of scala3_home.

I was also looking at @mbloms comment from 2020: "Some time in the future scala-dotty should be removed and the package base moved to scala3"; I do think that time has come :-).

@rubin55 - thanks, updated and will watch the issue report

Fwiw, I think upstream Scala 3.5.2 is broken. scalac does not seem to run normally and the jar files directory seems to be empty except for three manifest-only jars. I filed https://github.com/scala/scala3/issues/21926

@mbloms I sent you the patch for 3.3.0 via email. Please check when you have time
