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

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:

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.
