== Known issues and bugs
=== Symbolic links and `watchman`
`Buck` with activated `Watchman` has currently a
[known bug](https://github.com/facebook/buck/issues/341) related to
symbolic links. The symbolic links are used very often with external
plugins, that are linked per symbolic link to the plugins directory.
With this use case Buck is failing to rebuild the plugin artefact
after it was built. All attempts to convince Buck to rebuild will fail.
The only known way to recover is to weep out `buck-out` directory. The
better workaround is to avoid using Watchman in this specific use case.
Watchman can either be de-installed or disabled. See
link:#buck-daemon[Using Buck daemon] section above how to temporarily
disable `buckd`.
