gradle - 如何将 `ObjectFactory.namedDomainObjectList(…)`反向移植到Gradle(5.6.4)

Question

在gradle插件上工作。我试图将功能从gradle 6 ObjectFactory.namedDomainObjectList​(Class<T> elementType)移植到gradle 5.6.4。

我没有运气尝试过这个:

import org.gradle.testfixtures.ProjectBuilder
import org.gradle.api.internal.CollectionCallbackActionDecorator
import org.gradle.api.internal.DefaultDomainObjectCollection

def main() {
    def project = ProjectBuilder.builder().build();
    CollectionCallbackActionDecorator ccad;
    def myList = project.objects.newInstance(DefaultDomainObjectCollection.class,
                MyClass.class,
                new ListElementSource(),
                ccad);
}

static class MyClass implements Named {
    @Override
    String getName() {
        return "foobar"
    }
}

异常堆栈

这样解决:

def myList = new DefaultNamedDomainObjectList(
        MyClass.class,
        new Instantiator() {
            @Override
            def <T> T newInstance(Class<? extends T> aClass, Object... objects) throws ObjectInstantiationException {
                project.objects.newInstance(aClass, objects)
            }
        },
        new DynamicPropertyNamer())
