The --repl-no-load option is not recognized for build-type: Custom

[enobayram]

Describe the bug
I'm not able to start cabal repl with the --repl-no-load in Haskell packages specified to have build-type: Custom.

To Reproduce
Steps to reproduce the behavior:

I've prepared a GitHub repository to demonstrate this issue. So check out: https://github.com/enobayram/cabal-repl-no-load-test

Then in that folder, the following fails, even though a simple cabal v2-repl works.

$ cabal v2-repl --repl-no-load -v

Expected behavior
cabal v2-repl --repl-no-load should drop me down to a GHCi session that has no modules loaded.

System information

• Ubuntu 22.04
• cabal --version: 3.8.1.0
• ghc --version: 8.10.7

Additional context
Note that cabal v2-repl --repl-no-load works, if you change build-type to Simple in cabal-no-load-test.cabal

Hey @enobayram ! I’m really sorry it took so long to get back to you!

Thanks a lot for bundling up a reproducer, that will help a lot.

I believe currently, there’s very little energy for working on anything build-type: Custom-related. Some consider it a miss feature that eventually should be deprecated and removed. So, I hate to say this, but I’m not sure how much support you’ll get here. If you can look closer into -v3 output and try to figure what’s going wrong proactively and ask questions, chances are you’d get some feedback.

@ulysses4ever Thanks a lot for the response! Your input about build-type: Custom is valuable for me, leading me to believe that we should seek the solution in moving away from it.

@enobayram yes, avoiding it, if possible, is the preferred way to go forward.
