unresolved classes from installed plugin

Question

I am developing a custom plugin where is make use of groovys HTTPbuilder everything works fine when i run the plugin independently during tests(both manual and integration tests) However when i package and install the plugin in another app i get the following errors when running the app

unable to resolve class groovyx.net.http.HTTPBuilder
unable to resolve class groovyx.net.http.ContentType

I guess this has to do with dependency resolution but i do not know exactly what and why

Looks like you did not specify to the plugin to include HTTPBuilder when it is deployed. In BuildConfig.groovy you can specify your plugins like so:

dependencies {
    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or         
    build : 'lib/http-builder.jar' //If you are manually including the http builder jar
}
plugins {
    build: ':joda-time:1.1'
    test ':fixtures:1.0.RC1.SNAPSHOT',
    ':spock:0.4-groovy-1.7-SNAPSHOT'
}
