Plugin fails to apply when using Gradle plugin repository

[jpd236]

Tried using the new plugin DSL with the 1.0.18 plugin (now in the gradle repository, per #16).

plugins {
    id 'no.tornado.fxlauncher' version '1.0.18'
}

But I'm getting the following error:

...

The old system of adding a buildscript dependency and calling "apply plugin" continues to work fine.

I'm quite fond of the new id plugin DSL, so I'll be sad if it's broken.

@aalmiray, do you have any idea why this might be happening?

[aalmiray]

I think there's a change in the Gradle API. The code in question is

dependsOn: project.tasks.jar

I think the preferred way now is

dependsOn: project.tasks.findByName('jar')

This project relies on Gradle 2.13 (veeeery old) to build itself and publish. It may be the case that @jpd236 applied the plugin in a build that uses a more recent Gradle version.
