Is there any way to run specific plugins only after parent build ends?

[alvkn]

I have to copy some files in outDir after extension is built. I tried to use copy plugin, but in this case files are copied a few times (after each child build is completed). I want to avoid this, so I tried to override closeBundle hook and copy files manually, but this solution only works for build, not for dev. I cannot move my files to publicDir. Also, I tried to set enforce: pre/post to copy plugin, but there is no luck.

It would be great to have a callback arg that would be executed when parent build is completed
