cleanAfterEveryBuildPatterns behaviour

[Pierluigi Pesenti]

Issue description or question

I want to use the plugin for two purposes:

• cleaning the whole build folder before every run
• cleanup leftovers .js files that are only needed for CSS bundling. After the CSS extraction is done, I don't need those files anymore.

With the following configuration I have the following problems:
It seems like the glob pattern for the cleanAfterEveryBuildPatterns is behaving in a strange way:

'**/css/*.js'

is a pattern tested with many different glob libraries and online tools. It should match something like '/f67Hy/css/core.js', but it doesn't.
I also have subfolders in the 'css' folder so if I use

'**/css/**/*'

the subfolders are found and wiped, but if I try to wipe .js files only with

'**/css/**/*.js'

is doing nothing too. (I also tested this glob pattern).

Also, the plugin when verbose is set to true is printing details of what is cleaned BEFORE but not printing anything for what is being cleaned AFTER.
I am also considering the option this might just be a race condition.
I tried having the plugin run as the first plugin in the list or as the last, or even splitting it into two instances (one to run before and one after). Still no luck.

Thanks

So, after debugging the plugin I found the problem was that I need to set
protectWebpackAssets: false in the option.
To me, this was not clear. The plugin was adding all my files (not the folders) to the Globby (internally used to expand globs) ignore list, and tracing nothing about that.
I hope this can help someone.
