sbt new fails to parse arguments correctly on Windows

[ptrdom]

steps

Replicated on sbt 1.9.9, running Windows Terminal (PowerShell).

1. Open command line on Windows
2. Run sbt new foundweekends/giter8.g8 --name=example.g8 --giter8_version=0.16.2 --sbt_version=1.9.9

problem

Command does not run successfully, error is throw:

Error: Unknown option --name
Error: Unknown argument 'example.g8'
Error: Unknown option --giter8_version
Error: Unknown argument '0.16.2'
Error: Unknown option --sbt_version
Error: Unknown argument '1.9.8'
Try --help for more information.

Command does work on Linux, tested on WSL (Ubuntu).

expectation

sbt project should be created from the template successfully with arguments passed to the template.

notes

After experimenting with variations of command, one version I found to work was sbt new foundweekends/giter8.g8 "--name=example.g8 " "--giter8_version=0.16.2 " "--sbt_version=1.9.9 " - arguments must be enclosed in quotes and must be terminated by a space.
One strange variation was that enclosing all arguments in quotes - sbt new foundweekends/giter8.g8 "--name=example.g8 --giter8_version=0.16.2 --sbt_version=1.9.9" - created the sbt project, but with only the name argument set to example.g8 --giter8_version=0.16.2 --sbt_version=1.9.9, meaning that sbt project's directory would end up containing the remaining part of argument string.
This does not seem intentional, likely a bug in parser module.

Could also be a problem with launcher - it does extract the arguments that are then passed to sbt.

See also #2695. On Windows batch, equal sign = I think is treated as whitespace.

So apparently = is a default delimiter in batch scripts, workarounds for this issue seem to be present for certain types of arguments in launcher script already.

I am starting to think that it would be better to just start out fresh with a v2 cross-platform launcher script/app instead of keeping on patching these issues separately. Similar to how in g8 project the launcher script is just a Java app.
