[mdittmer]

Issue description in commit message here: mdittmer/bazel-sandbox@03b685b (commit contains code to reproduce issue).

This issue was observed running bazel on mac with rules_swc-0.5.1.

Description copied here for convenience:

swc() rule that compiles transitive dependencies succeeds on first build, but fails on second build while copying files.

$ cd js && npm install && bazel clean --expunge && bazel build //:swc && bazel build //:swc
npm WARN bazel-swc-test@0.0.1 No description
npm WARN bazel-swc-test@0.0.1 No repository field.

Copying file bazel-bin/node_modules/aws-sdk/scripts/services-table-generator.ts is the clue here. Your glob to gather .ts inputs is descending into the bazel output folder. You should probably add bazel-bin/node_modules/ to .bazelignore.
