评估后测试自定义分级插件

Question

@Before fun setup() {
  project = ProjectBuilder.builder().build()
  project.pluginManager.apply("my.plugin.name")

assertTrue(project.extensions.findByName("name") is MyConfigType)

assertTrue(project.tasks.findByName("mytask") is MyTaskType)

是否有一种不同的方式来接收价值？

我在gradle论坛上发布了我的类似问题，并解决了这个问题:https://discuss.gradle.org/t/unit-test-plugins-afterevaulate/37437/3

显然，afterevalue不是执行任务创建的最佳/正确位置。如果扩展中有DomainObjectCollection并且希望为集合中的每个元素创建任务，则任务创建应在集合的All回调中完成：

final MyExtension extension = project.getExtensions().create("extension", MyExtension.class);
extension.configurations.all((c) -> {
  // register task here
});

如果扩展中有简单的属性作为输入提供给任务,则应使用惰性配置：

public class MyExtension { 
  public final Property<String> property;
  public final NamedDomainObjectContainer<Configuration> configurations;

  @Inject
  public MyExtension(final ObjectFactory objectFactory) {
    property = objectFactory.property(String.class).convention("value");
    configurations = objectFactory.domainObjectContainer(Configuration.class);
  }
}

public abstract class MyTask extends DefaultTask {

  @Input
  private final Property<String> property = getProject().getObjects().property(String.class);

  public Property<String> getProperty() {
    return property;
  }
}

public class MyPlugin implements Plugin<Project> {

  @Override
  public void apply(final Project aProject) {
    final MyExtension extension = aProject.getExtensions().create("extension", MyExtension.class);
    aProject.getTasks().register("myTask", MyTask.class).configure((t) -> {
      t.getProperty().set(extension.property);
    });
  }
}
