localGroovy method within plugin groovy code - gradle

Question

In my plugins, I am always trying to add Groovy to Java. Now this code works just fine when in a build.gradle file, but when I move it to a plugin groovy file so I can compile it and distribute it, it says it can't find the method localGroovy(). What's the correct syntax to call the localGroovy() method here?
project.with {
plugins.withType(JavaPlugin) {
//noinspection GroovyAssignabilityCheck
configurations.all {
resolutionStrategy {
force localGroovy()
}
}
}
}

The method localGroovy() is defined in the DependencyHandler interface. I don't know where in your build script you were using the above code snippet, but you would need to be in the scope of a DependencyHandler to access this method. However, in your plugin, you could just use the DependencyHandler under projects.dependencies:
[...]
resolutionStrategy {
force project.dependencies.localGroovy()
}
[...]
Please note, that I did not test this code and it relies on your statement that the used method force(...) can handle whatever Dependency implementation is returned by localGroovy().
According to the docs, the force(...) method can handle the following inputs:
String in a format of: 'group:name:version', for example: 'org.gradle:gradle-core:1.0'
instance of ModuleVersionSelector
any collection or array of above will be automatically flattened
As long as the Dependency returned by localGroovy() implements the ModuleVersionsSelector interface (e.g. as ExternalDependency), the solution above should work like a charm.
