I'm pretty sure this is not an issue in Dagger per se but rather https://github.com/bazelbuild/rules_jvm_external/issues/291.

That suggests that it could be resolved by updating some dependencies. When I first encountered this (a couple months ago), I tried updating just rules_jvm_external, but I still got the error, and I got the impression that maybe an old version of rules_jvm_external is still pulled transitively through rules_kotlin or something? Or maybe I did it wrong. Sorry, it's been a while since I initially encountered this, so I'm working from notes.

Fortunately, installing python-is-python3 (or putting an appropriate executable named python somewhere in your $PATH (or maybe alternatively at the location of $PYTHONPATH?) is a workaround.

I think this is also https://github.com/bazelbuild/bazel/issues/12485
