【问题描述】：

我正在尝试为 android 添加 allopen 插件。

我将此添加到我的build.gradle(.)

ext.kotlin_version = '1.3.61'

classpath "org.jetbrains.kotlin:kotlin-allopen:$kotlin_version"

我将此添加到我的app/build.gradle

apply plugin: 'kotlin-allopen'
apply plugin: 'io.fabric'

allOpen {
    annotation('com.myapp.sidemodule.Mockable')
}

由于项目结构，注解与属于 App 的模块位于不同的模块中

我添加了这个在sidemodule/debug/Mockable中

@Target(AnnotationTarget.ANNOTATION_CLASS)
annotation class Mockable

然后这个在sidemodule/debug/OpenClass中

@Mockable
@Target(AnnotationTarget.CLASS)
annotation class OpenClass

然后这个在sidemodule/release/OpenClass中

@Target(AnnotationTarget.CLASS)
annotation class OpenClass

我添加了 @OpenClass给我注定要被嘲讽的班级但是，我仍然收到：

我该如何解决？

【问题讨论】：

你能不能尝试用注解类 Mockable 的 @Target(AnnotationTarget.CLASS) 替换 @Target(AnnotationTarget.ANNOTATION_CLASS) ？
它没有帮助。

【解决方案1】：

只是在这里尝试同样的事情......这对我有用

我在build.gradle添加了关注

allOpen {
    annotation('com.mypackage.OpenForTesting')
}

然后在com.mypackage里面创建了一个OpenForTesting.kt文件

@com.mypackage.OpenForTesting
annotation class OpenForTesting

然后最后加上@OpenForTesting注解

@OpenForTesting
class SomeClassUnderTest {
