我好像搞不懂这个问题..。

我尝试过各种各样的方法来保持所需的类，并寻找了很长一段时间来找到解决方案.

当我应用专业护卫，应用程序崩溃与此错误。

我用的是改造2.9.0和moshi 1.13.0和moshi 1.13.0

原因: java.lang.ClassNotFoundException:没有找到类ApiResponseJsonAdapter

ApiResponse是具有泛型类型的模型

代码语言：javascript
运行
复制
@Keep
@JsonClass(generateAdapter = true)
data class ApiResponse<T>(
    @Json(name = "detail")
    val message: String,
    @Json(name = "result")
    val result: T
)

拜托我需要帮助。提前谢谢。

更新这是我的专业护卫

我已经解决了问题。我意识到Moshi的Kotlin-codegen工件不是生成的，所以我从终端运行gradle构建，发现Moshi需要使用Java 16，但我使用的是默认的Android。在转换了所有东西之后，一切都像魅力一样，用各种各样的方法修复，比如

包括下面的语句到gradle属性。

非物质主义者=moshi-1.13.0

这就是Moshi Docs关于反射的内容：

反射适配器使用Kotlin的反射库将Kotlin类转换为JSON。通过将KotlinJsonAdapterFactory添加到Moshi.Builder中来启用它：

代码语言：javascript
运行
复制
val moshi = Moshi.Builder()
    .addLast(KotlinJsonAdapterFactory())
    .build()

考虑到这一点，您应该在gradle中拥有库和Moshi的Kotlin支持和转换器工厂。

代码语言：javascript
运行
复制
implementation "com.squareup.moshi:moshi:1.12.0"
implementation "com.squareup.moshi:moshi-kotlin:1.12.0"
implementation 'com.squareup.retrofit2:converter-moshi:2.9.0'

如果使用DI，则可以在构建Retrofit对象时执行类似的操作：

代码语言：javascript
运行
复制
@Provides
    @Singleton
    fun provideNeowsAPI(): NeowsAPI {
  //add the JsonAdapter factory to use when build the Moshi object
    val moshi = Moshi.Builder().addLast(KotlinJsonAdapterFactory()).build()
        return Retrofit.Builder()
                .baseUrl(NeowsAPI.BASE_URL)
                . addConverterFactory(ScalarsConverterFactory.create())
                .addConverterFactory(MoshiConverterFactory.create(moshi))
                .build()
                .create(NeowsAPI::class.java)
    }

如果不使用DI，则可以构建Moshi对象，然后将其添加到中。

代码语言：javascript
运行
复制
//Build Moshi Object
private val moshi =
    Moshi.Builder()
        .addLast(KotlinJsonAdapterFactory())
        .build()

//Build Retrofit Object
val retrofit =
    Retrofit.Builder()
        .addConverterFactory(ScalarsConverterFactory.create()) // for parsing JSON String
        .addConverterFactory(MoshiConverterFactory.create(moshi)) //for parsing KotlinObjects i.e.
        // picture of the day
        .baseUrl(BASE_URL)
        .build()
