Fails with 'Could not generate a decorated class for class cz.malohlava.VisTaskExecGraphPlugin."

[bruno-garcia]

I apply the plugin:

Kotlin DSL:

    id("cz.malohlava") version "1.0.3"

but it fails with:

* What went wrong:
An exception occurred applying plugin request [id: 'cz.malohlava', version: '1.0.3']
> Failed to apply plugin [id 'cz.malohlava']
   > Could not create plugin of type 'VisTaskExecGraphPlugin'.
      > Could not generate a decorated class for class cz.malohlava.VisTaskExecGraphPlugin.
