Flag --incompatible_disable_starlark_host_transitions will break rules_haskell in Bazel 7.0

[keertk]

Incompatible flag --incompatible_disable_starlark_host_transitions will be enabled by default in the next major release (Bazel 7.0), thus breaking rules_haskell. Please migrate to fix this and unblock the flip of this flag.

The flag is documented here: bazelbuild/bazel#17032.

Please check the following CI builds for build and test results:

• Ubuntu 18.04 OpenJDK 11

Never heard of incompatible flags before? We have documentation that explains everything.
If you have any questions, please file an issue in https://github.com/bazelbuild/continuous-integration.

Hi @ylecornec, Can you share any significant update on this issue. Thanks!

[ylecornec]

Hi @sgowroji, PRs #1909 and #1911 should fix the issue once they are merged (the second one enables --incompatible_disable_starlark_host_transitions with bazel 6 in the CI).

Hi @ylecornec, We are still seeing few failures for the above incompatible flag in the pipeline. Can you please have a look Thanks!

Hi @sgowroji. How is this IOException related to the incompatible flag? Also the CI run you linked to seems to be green.
