Fix publishing for 2.13.16 and 3.6.3

[kiendang]

3.6.3

• DottyParser.blockStatSeq signature change from 3.6.2 to 3.6.3

  See scala/scala3@3.6.2...3.6.3#diff-89e03cdd16b8e5fd6435d2df4b44a3e58c408a22adb7683c149015ab0d64f4bfR4717
  

  Thus the current amm/compiler/src/main/scala-3/DottyParser.scala is moved to .../scala-3.0.0-3.6.2/DottyParser.scala. A new .../scala-3.6.3+/DottyParser.scala was created with the new signature. build.mill was updated accordingly.

2.13.16

• A change in upstream (Issue messages at import selector only [ci: last-only] scala/scala#10868) caused an error in autocompletion. Attempting to autocomplete import java.| would trigger the error. The workaround is to change the autocomplete code wrapper to

  object AutocompleteWrapper{
  def main(args: Array[String])={
  import java.
  ()
  }}

  (similar to Scala 3)

  instead of

  object AutocompleteWrapper{
  import java.}

3.6.3 is green now.

2.13.16 has an issue related to completion

import java.|

would lead to import java.[Current.sc]: exception during background compile: java.lang.AssertionError: assertion failed: bad position: [909:908].

haven't been able to go far from the error message, but this could be related to scala/scala#10868.

@lihaoyi I figured out the issue with 2.13.16. It's related to upstream. See my comment here.

[lihaoyi]

Thanks @kiendang !

[kiendang]

@lihaoyi 2.13.16 is also green now. Work around the upstream issue by tweaking the autocomplete code wrapper. See scala/scala#10868 (comment).

Thanks @kiendang ! Could you fill out the PR description with a summary of your changes in Scala 2 and 3, along with links to the upstream tickets? Then I can merge this and transfer the bounty

[kiendang]

@lihaoyi done. I've also just updated so the diff is minimal now. For 3.6.3 amm/compiler can just reuse the same code as scala-3.5.0+, except for 1 change in DottyParser.

Thanks @kiendang! I'll transfer the bounty using the bank details we for the last one
