nebula-test fails to load the project plugin class when using IntegrationSpec class

Question

I'm in the process of writing and testing a Gradle plugin. When I try to test the plugin I get an error indicating the plugin class can't be found? If I use the plugin id I get: Plugin with id <> not found. If I use the plugin class name I get: Could not find property 'com' on root project.

Below is the build.gradle, ExamplePlugin class and the Test Spec.

build.gradle

apply plugin: 'idea'
apply plugin: 'groovy'
apply plugin: 'maven'

group = 'com.sas'
version = '0.1.0'

description = "Project to test with nebula plugin."

task wrapper(type: Wrapper) {
    gradleVersion = '2.6' //version required
}

repositories {
    jcenter()
    mavenCentral()
}

dependencies {
    compile localGroovy()
    compile gradleApi()

    testCompile 'org.spockframework:spock-core:1.0-groovy-2.3'
    testCompile 'com.netflix.nebula:nebula-test:3.1.0'
}

plugin class

package com.sas.gradle.plugins.example

import org.gradle.api.Plugin
import org.gradle.api.Project

class ExamplePlugin implements Plugin<Project> {
    @Override
    void apply(Project project) {
        project.logger.debug("ExamplePlugin: Running...")
    }
}

test class spec

package com.sas.gradle.plugins.example

import nebula.test.IntegrationSpec
import nebula.test.functional.ExecutionResult

class ExamplePluginIntegSpec extends IntegrationSpec {

    def 'setup and display the buildscript classpath'() {
        writeHelloWorld('example.hello')
        buildFile << '''
            apply plugin: 'java'
            apply plugin: com.sas.gradle.plugins.example.ExamplePlugin
            task show << {
                buildscript.configurations.classpath.each { println it }
            }
        '''.stripIndent()

        when:
        ExecutionResult result = runTasksSuccessfully('show')

        then:
        result.standardOutput.contains(':show')
    }
}

It appears when using the IntegrationSpec it creates build scripts build.gradle and settings.gradle in build/test/package/spec location. Also, I see .gradle, .gradle-test-kit, src directories at the same location. I was wondering how the .classpath is setup for running the tests and noticed an init.gradle script in the .gradle-test-kit; then in it I found a allprojects->buildscript->dependencies>classpath DSL. Then I noticed my plugin class (compiled to build/classes/main) wasn’t in the list? I’d have thought nebula-test IntegrationSpec class would have done this? By adding this DSL:

buildscript {
    dependencies {
        classpath files('../../../../build/classes/main')
    }
}

Thanks in advance for any help, Jim

Lastly here's the exception I get:

Is that how your project looks like: https://github.com/Opalo/stackoverflow/tree/master/34771078 ? The test passess. — Opal, Jan 14 '16 at 08:37
I just grabbed the code; it fails on my machine. I'm running on Windows with Java version "1.8.0_25". What environment are you using? — James Poli, Jan 14 '16 at 14:37

Have you taken a look at Gradle TestKit (the functional replacement for Nebula test)? Take a look at the specific section about placing the code under test on the classpath.

Thanks, Mark, that certainly helps. I'll give it a try. – James Poli Jan 14 '16 at 14:27
