gradle - Gradle 4.6 + Junit 5: `-Dtest.single`不起作用吗？

Question

使用Gradle 4.6，我制作了一个 super 简单的测试项目来测试JUnit 5的兼容性。似乎-Dtest.single不起作用。我已经搜索了文档，我想运行一个测试类和/或一个测试方法。我在这里

 gradle clean -Dtest.single=junittest.SampleTests test

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':test'.
> Could not find matching test for pattern: junittest.SampleTests

我有一个故意失败的测试案例 failingTest():

gradle clean test

> Task :test FAILED

junittest.SampleTests > failingTest() FAILED
    org.opentest4j.AssertionFailedError at SampleTests.java:16

我的build.gradle:

apply plugin: 'java'

sourceCompatibility = 8

repositories {
  mavenCentral()
  maven { url "http://packages.confluent.io/maven/" }
}

test {
  useJUnitPlatform()
}

tasks.withType(JavaCompile) {
  options.compilerArgs << "-Xlint:unchecked"
}

dependencies {
  testImplementation 'org.junit.jupiter:junit-jupiter-api:5.1.0'
  testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.1.0'
}

根据documentation，test.single选项基于文件名模式，即，当您将.替换为/时，它可以工作:

./gradlew clean test -Dtest.single=junittest/SampleTests

但是，在大多数情况下，使用 --tests选项更容易:

./gradlew clean test --tests junittest.SampleTests
