Unable to create generate a WAR file after upgrading to Webpack 5

[stertheweb]

I am unable to generate a WAR file with this plugin after upgrading to Webpack 5. The specific error I get is:

Generating minified bundle. This will take a moment...
Error:  TypeError: compiler.plugin is not a function

Webpack 5 does not support compiler.plugin for any function. Is there any way that this package could be updated?
