How could I get webpack version in plugin

[yangguansen]

I'm making a webpack plugin, for compatible webpack@4 and webpack@5, how could i get webpack version in apply()?

[vankop]

in webpack@5 compiler has webpack property (compiler.webpack). Also if you want full version in webpack@5 compiler.webpack.version

So how could i get flag of webpack@4?

[vankop]

const isWebpack5 = "webpack" in compiler

otherwise it is webpack@4
