Using a plugin from separate Gradle Script - gradle

Question

I have been using a plugin to generate some documentation. When I place the code for it inside the build.gradle for each package it works perfectly.
However instead of having this plugin in multiple build.gradle files I want to place it in a separate gradle script to keep everything more central.
However when i do this I get an error of :
Plugin with id 'com.benjaminsproule.swagger' not found.
Despite the code being the exact same as when it is in the build.gradle file.
Here is the code to import the plugin and use it:
buildscript {
repositories {
maven {url "http://jcenter.bintray.com"}
}
dependencies {
classpath 'com.benjaminsproule:swagger-gradle-plugin:0.0.8'
}
}
apply plugin: 'com.benjaminsproule.swagger'
swagger {
apiSource {
springmvc = false
locations = ['package1']
info {
title = 'Package 1'
version = 'v1'
description = 'Documentation for Package 1'
}
swaggerDirectory = "${project.rootDir}/reports/Package1"
}
apiSource {
springmvc = false
locations = ['package2']
info {
title = 'Package 2'
version = 'v1'
description = 'Documentation for Package 2'
}
swaggerDirectory = "${project.rootDir}/reports/Package2"
}
}
So I want to move this all from build.gradle to a file called swagger.gradle, is this possible?
I also run the plugin using:
gradle swagger

Answer 1

Figured out a solution myself, might be useful for anyone else who runs into this problem.
I created a Swagger.gradle file which contained the buildscript and the build.gradle then called in the plugin.
For Apply plugin I had to called directly the main class of the plugin.
Swagger.gradle
buildscript {
repositories {
maven {url "http://jcenter.bintray.com"}
}
dependencies {
classpath 'com.benjaminsproule:swagger-gradle-plugin:0.0.8'
}
}
apply plugin: com.benjaminsproule.swagger.gradleplugin.GradleSwaggerPlugin
Build.gradle
apply from: "/scripts/Swagger.gradle"
swagger {
apiSource {
springmvc = false
locations = ['package1']
info {
title = 'Package 1'
version = 'v1'
description = 'Documentation for Package 1'
}
swaggerDirectory = "${project.rootDir}/reports/Package1"
}
apiSource {
springmvc = false
locations = ['package2']
info {
title = 'Package 2'
version = 'v1'
description = 'Documentation for Package 2'
}
swaggerDirectory = "${project.rootDir}/reports/Package2"
}
}
