android - ApolloGraphql 文件未找到异常 : source/apollo/generatedIR/debug/src (Is a directory)

Question

我正在尝试将 ApolloGraphql 添加到我的 android 项目中，但是当我尝试重建项目时，我得到:

org.gradle.api.UncheckedIOException: java.io.FileNotFoundException: /Users/mcebotari/Downloads/Projects/Barcloud/app/build/generated/source/apollo/generatedIR/snapshotDebug/src (Is a directory)

在 build.gradle 中，我添加了所需的依赖项:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

apply plugin: 'com.apollographql.android'

  androidTestImplementation 'com.android.support.test:runner:1.0.2'

}

还有依赖:

classpath 'com.apollographql.apollo:apollo-gradle-plugin:1.0.0-alpha'

尝试重建我得到的项目:

org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:generateDebugApolloClasses'.
    at org.gradle.api.internal.tasks.execution.ExecuteActionsTaskExecuter.executeActions(ExecuteActionsTaskExecuter.java:100)

graphql 文件来自官方示例 - GithuntFeedQuery.graphql 及其 schema.json，粘贴在主文件夹中。

有什么想法吗？

Answer 1

在研究这个问题时，我遇到了两种解决方案:

1. 从您的项目中删除 apollo，(通过编辑您的 gradle 文件) 清理您的项目，然后再次添加 apollo。

2. 尝试更改项目 gradle 文件中的 apollo 版本，IE。我和

一起工作

classpath 'com.apollographql.apollo:gradle-plugin:0.3.1

最初是 0.3.2。
