我有一个Gradle项目，该项目使用通过工具链API指定的Java版本：

val minimumJava = JavaLanguageVersion.of(8)
val maximumJava = JavaLanguageVersion.of(16)
java {
    toolchain {
        languageVersion.set(minimumJava)
        vendor.set(JvmVendorSpec.ADOPTOPENJDK)
    }
}

我希望能够使用支持的最低Java版本进行编译，然后使用项目支持的所有JDK运行测试。我尝试了以下方法，但显然只有原始测试得到执行，所有其他测试都没有执行，即使所需的JDK已正确下载并设置：

for (javaVersion in JavaLanguageVersion.of(minimumJava.asInt() + 1)..maximumJava) {
    val base = tasks.test.get()
    val testTask = tasks.register<Test>("testUnderJava${javaVersion.asInt()}") {
        javaLauncher.set(
            javaToolchains.launcherFor {
                languageVersion.set(javaVersion)
            }
        )
        classpath = base.classpath
        testClassesDirs = base.testClassesDirs
        isScanForTestClasses = true
    }
    tasks.test.configure { finalizedBy(testTask) }
}

下面是一个在哑终端中运行的示例：

❯ TERM=dumb ./gradlew test testUnderJava10 --rerun-tasks --scan
Picked up _JAVA_OPTIONS: -Dawt.useSystemAAFontSettings=on

<<<SNIP>>>

> Task :testClasses

> Task :test

从build scan来看，似乎没有执行测试，而是使用JDK8执行测试。我很困惑，the docs说这应该很简单：

tasks.register<Test>("testsOn14") {
    javaLauncher.set(javaToolchains.launcherFor {
        languageVersion.set(JavaLanguageVersion.of(14))
    })
}
