Copy-webpack-plugin: DeprecationWarning: Tapable.plugin is deprecated. Use new API on `.hooks` instead

[fregante]

I'm using with copy-webpack-plugin 4.4.1 with webpack 4.0.0-beta.0 and I get this warning (although it seems to work since #211)

[alexander-akait]

@bfred-it expected behavior, will be fixed in next major, after webpack@4 will be official release

[michael-ciniawsky]

This will stay for a while since the plugin needs to support webpack =< v4.0.0 and webpack 4 has a compat layer for the 'old' plugin system

[alexander-akait]

@michael-ciniawsky in theory we can check on new api and use new api

[michael-ciniawsky]

This is handled by the compat layer in webpack imho. A option/flag to disable the warnings would be awesome, but this should also happen in webpack/webpack instead

[alexander-akait]

@michael-ciniawsky --ignore-deprecation for webpack will be good

[michael-ciniawsky]

Yep, something like that or a sledgehammers --silent [...options] mode, since webpack can be quite noisy in general sometimes (e.g loader warnings per file/request) :)

Webpack 4 is now available.

[michael-ciniawsky]

Someone can send PR which feature detects webpack >= v4.0.0 via

const cb = (...args) => {}

...

if (compiler.hooks) {
  const plugin = { name: 'CopyPlugin' }

  compiler.hooks.someHook.tap(plugin, cb)
} else {
  compiler.plugin('some-hook', cb)
}

Webpack 4 supported?

[alexander-akait]

Let's do it in next patch. WIP
