build.lua has no access to plugin dir

Loader.source(build_file)

From reading the code, I think this line has the issue, that, if a plugin specifies a build.lua file, it gets sourced into the current neovim lua runtime, thereby sharing its CWD.
The build file typically wants a CWD equal to plugin dir.
That is already the case if the build property is a script or a function (via the plugin spec parameter).

Furthermore, if the build is a lua file or a function, it does not seem to run async.

build(self.plugin)

If this is correct, what would I need to change to run build.lua in plugin.dir and make it and the function variant async?

• coroutines?
• vim.uv.new_thread?
• spawn new nvim --headless -c ?
