Plugin fails with babel 7.6.4 #8

Plugin fails with message

Failed on Babel transpile execution. java.lang.RuntimeException: javax.script.ScriptException: ReferenceError: "WeakMap" is not defined in at line number

I suppose that Babael 7.6.4 does not include WeakMap polyfill which is needed to be addressed during build process. It would be nice to have an option to configure babel execution runtime in plugin configuration

The plugin only works with https://registry.npmjs.org/babel-standalone/-/babel-standalone-6.26.0.tgz. Since 7.x it misses polyfills for nashorn. https://github.com/babel/babel/issues/7607

Please check current master (no bundle yet).

@buckelieg, version 1.4 works flawlessly with @babel/standalone 7.8.7
