How do I apply a plugin to a project from a (shared) applied .gradle file?

Charley, were you able to get this to work? I’m struggling with a very similar solution, but when I omit the quotes in the apply and use the fully qualified classname for my plugin:

apply plugin: com.stibo.gradle.plugin.stibodefaults.StiboDefaults

I get this error: Could not find property ‘com’ on project ‘:components-mapper’.
