groovy - 使用IntegrationSpec类时，nebula-test无法加载项目插件类

Question

我正在编写和测试Gradle插件。当我尝试测试插件时，出现错误消息，指示找不到插件类？如果使用插件ID，则会得到:找不到ID为<>的插件。如果使用插件类名称，则会得到:在根项目上找不到属性“com”。

以下是build.gradle，ExamplePlugin类和测试规范。

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'
}

插件类

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...")
    }
}

测试类规范

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')
    }
}

使用IntegrationSpec时，它会在build / test / 包 / spec 位置中创建构建脚本build.gradle和settings.gradle时显示。另外，我在同一位置看到.gradle，.gradle-test-kit，src目录。我想知道如何设置.classpath来运行测试，并注意到.gradle-test-kit中有一个init.gradle脚本。然后在其中找到了allprojects-> buildscript-> dependencies> classpath DSL。
然后我注意到我的插件类(编译为build / classes / main)不在列表中？我以为星云测试IntegrationSpec类会做到这一点？通过添加此DSL:

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

预先感谢您的帮助，

您是否看过Gradle TestKit(星云测试的功能替代品)？看一下有关将测试代码放在类路径上的specific section。
