// Let's say we have a gradle plugin. Now we want that gradle plugin project to actually use the exact plugin.
// There are probably multiple ways we can bootstrap this. One way is to build the jar, and use that, but that's boring.
// Here we show how we can have the plugin-project use the actual plugin we are building.

// :: We load the groovy script on runtime, only then are we able to apply the plugin
// Setup the groovy classpath. Start with our own files
def classpaths = [file('src/main/groovy').absolutePath, file('src/main/resources').absolutePath]
// The groovy script engine wants a string array
String[] classpathArray = classpaths.toArray(new String[classpaths.size()]);
// Start a groovy script engine with our classpaths
