gradle - Gradle:如何使用自定义配置运行自定义任务？

Question

我正在尝试添加一个自定义的Gradle任务，该任务运行一组测试并将结果上载到报表服务。该服务使用的依赖项仅应在运行此任务时解决。

我的理解是，通常要创建一个包含相关依赖项的自定义配置，这已经完成了。现在如何将此配置添加到任务中？

我尝试使用from关键字，但出现以下错误:

> Could not find method from() for arguments [configuration ':rp'] on task ':regression' of type org.gradle.api.tasks.testing.Test.

我还按照 this answer的描述使用了 configurations.rp.each()，但是我收到了NullPointerException。这是该堆栈跟踪:

我的 build.gradle 的相关部分:

configurations {
    rp {
        extendsFrom compile
        transitive=true
    }
}

dependencies {
    compile "org.slf4j:slf4j-simple:1.7.7"

我想得太多了。解决方案最终只是在任务中添加依赖项:

dependencies {
    compile "org.slf4j:slf4j-simple:1.7.7"
    compile group: 'com.github.javafaker', name: 'javafaker', version: '0.14'
    compile group: 'com.googlecode.json-simple', name: 'json-simple', version: '1.1'
    compile group: 'org.apache.pdfbox', name: 'pdfbox', version: '2.0.3'
}

tasks.withType(Test) {

    testLogging {
        outputs.upToDateWhen {false}
        showStandardStreams = true
    }

    systemProperties System.getProperties()

    test.finalizedBy(aggregate)
}

task regression(type: Test) {

    dependencies {
        compile "com.github.invictum:serenity-reportportal-integration:1.3.0"
    }

    def env = !System.properties.containsKey("environment") ? "DEV" : System.getProperty("environment").toUpperCase()
    def zone = TimeZone.getTimeZone("US/Mountain")
    def cal = new GregorianCalendar(zone)
    def now = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss a z").format(cal.getTime())
    systemProperty "rp.description", env + " " + now
    systemProperty "rp.launch", "Proposal Regression Suite"
}

gradle.startParameter.continueOnFailure = true
