Fail to compile tsetse due to overwriting outputs

[achew22]

Running rules_typescript from inside a container is failing @ d3cc5cd72d89aee0e4c2553ae1b99c707ecbef4e (current HEAD as of posting).

Inside my docker container when I run bazel build @build_bazel_rules_typescript//internal/tsetse/rules:rules (not discovered by running it directly, I tried to build my target and this was a dep) I get:

ERROR: /var/jenkins_home/.cache/bazel/_bazel_jenkins/012289bd6d606b886bac5c41b583ff44/external/build_bazel_rules_typescript/internal/tsetse/rules/BUILD:19:1: Compiling TypeScript (devmode) @build_bazel_rules_typescript//internal/tsetse/rules:rules failed (Exit 1)

Have you seen anything like this before? I tried to put together a minimal version of this bug, but thus far have been unable to do so. I'm happy to keep trying but I think I need a pointer to what is different. Unfortunately this was in the CL where I switched to rules_typescript so I have a +1500/-22000 line diff to comb through to figure out if it is something in there.

Yes, it's a hermeticity violation with the vanilla typescript compiler (once we've compiled tsc_wrapped we have a workaround for this problem, which is that we elide unexpected writes to disk. But to compile tsc_wrapped itself, we have to work with plain tsc)

@gregmagolan has found this is blocking us on Windows as well. I'll work on it tomorrow probably.
