Setting up Gradle Cargo - gradle

Question

I am trying follow this tutorial to set up Grails/ Cargo: https://github.com/bmuschko/gradle-cargo-plugin I wish to use this plugin to deploy wars to local tomcat instances and to start and stop them.
Here is my build.gradle
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'cargo'
sourceCompatibility = 1.5
version = '1.0'
jar {
manifest {
attributes 'Implementation-Title': 'Gradle Quickstart', 'Implementation-Version': version
}
}
repositories {
mavenCentral()
}
dependencies {
compile group: 'commons-collections', name: 'commons-collections', version: '3.2'
testCompile group: 'junit', name: 'junit', version: '4.+'
classpath 'org.gradle.api.plugins:gradle-cargo-plugin:0.6.1'
def cargoVersion = '1.3.3'
cargo "org.codehaus.cargo:cargo-core-uberjar:$cargoVersion",
"org.codehaus.cargo:cargo-ant:$cargoVersion"
}
cargo {
containerId = 'tomcat6x'
port = 9090
deployable {
file = file('/Users/me/Documents/gradlemucks/grails_2/hello-world/target/hello-world-0.1.war')
context = 'helloworld'
}
local {
homeDir = file('/Users/me/developer/servers/apache-tomcat-6.0.37')
output = file('build/output.log')
tomcat {
ajpPort = 9091
}
}
}
test {
systemProperties 'property': 'value'
}
uploadArchives {
repositories {
flatDir {
dirs 'repos'
}
}
}
When I do gradle tasks in the terminal I get:
FAILURE: Build failed with an exception.
* Where:
Build file '/Users/me/Documents/workspaces/regress_test/httptests/build.gradle' line: 3
* What went wrong:
A problem occurred evaluating root project 'httptests'.
> Plugin with id 'cargo' not found.
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
What are my doing wrong?

The buildscript itself need the cargo dependency so adding:
buildscript {
repositories {
mavenCentral()
}
dependencies { classpath "org.gradle.api.plugins:gradle-cargo-plugin:0.6" }
}
should make it able to find the cargo plugin.
