Is there a way to specify dependencies for a newly created sourceset in gradle?
sourceSets{
               servicetest{
                           java.srcDirs = [//path to servicetests]
               }
    }

dependencies{
                servicetest(group: 'org.testng', name: 'testng', version: '5.8', classifier: 'jdk15')
   }

configurations {
    serviceTestCompile
}

sourceSets {
    serviceTest {
        compileClasspath = configurations.serviceTestCompile
    }
}

dependencies {
    serviceTestCompile "org.testng:testng:5.8"
}
