在 Debug 但不是 Release 中构建 AppSync 项目时 generateClasses 中的异常

Question

我正在处理的项目仅在构建变体为 Debug 时才会出现以下错误 - 而对于 Release，代码生成良好，项目构建和 AppSync 工作。

只有在Debug变体中才会出现以下错误：

java.io.FileNotFoundException: /Users/mike/Documents/Development/Mantra/Android/app/build/generated/source/appsync/generatedIR/debug/src (Is a directory)

运行任务步骤的堆栈跟踪是：

GenerateDebugApolloIR 任务为绿色并正常完成

GenerateDebugApolloClasses 是红色的，子任务 generateClasses 错误如下。没有生成 java 文件并且构建失败并出现以下错误：

谁能指出我正确的方向来解决这个问题？

Answer 1

在此处重新发布我对类似问题的回答：ApolloGraphql FileNotFoundException: source/apollo/generatedIR/debug/src (Is a directory)

与 prodRelease 配置有同样的问题，通过重命名 prod flavor 来解决。 在应用程序 build.gradle 我有：

buildTypes { 
  debug {...}
  release {...}
}
productFlavors {
  dev {...}
  stage {...}
  prod {...}
}

这给了我 6 个 buildVariants

devDebug
devRelease
stageDebug
stageRelease
prodDebug
prodRelease

前 5 个在本地和 CI 上构建没有问题，而 prodRelease 给了我与你描述的相同的错误，没有任何逻辑解释。 GraphQL 文件对于 dev、stage 和 prod 是相同的......我尝试为“prod”创建特定文件夹，然后为“prodRelease”创建特定文件夹，检查它们的访问权限 - 所有变体都相同，没有任何帮助。 prodDebug 一直在正确构建。然后我重命名了 prod flavor（不要忘记相应地重命名 graphql 文件夹），它现在就像一个魅力。
