#18597 Various JavaScript rules fail to bootstrap on 2.17-dev if the cached JavaScript toolchain is corrupted Issue created by chrisjrn I'm running

./pants test --changed-since=origin/main

, which is failing because the JavaScript parser rules can't get bootstrapped:

Use `--keep-sandboxes=on_failure` to preserve the process chroot for inspection.

It appears as though there are

javascript_sources

in

BUILD

files in the Pants repo that require specific dependencies to be present on the machine. Disabling the

javascript

backends fails because there are

javascript_sources

in the repo. pantsbuild/pants
