适用于Android的自定义Gradle测试任务

问题

我想创建一个自定义的gradle测试任务，使其仅运行JUNIT测试并省略Robolectric测试.我正在尝试通过创建新的测试注释并省略任何包含该新注释的测试来实现此任务.

I want to create a custom gradle test task to only run JUNIT tests and omit Robolectric tests. I am attempting to achieve this task by creating a new test annotation and omitting any tests that include that new annotation.

错误

运行gradle任务时不包含JUNIT软件包.

JUNIT packages are not included when I run the the gradle task.

error: package android.test.suitebuilder.annotation does not exist
import android.test.suitebuilder.annotation.SmallTest;

详细信息

新注释

@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.METHOD, ElementType.TYPE})
public @interface RobolectricTest {
}
