ApolloGraphql FileNotFoundException: source/apollo

Question

I am trying to add ApolloGraphql to my android project, but when i try to rebuild the project, i get :

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

in build.gradle i have added the needed dependencies:

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

apply plugin: 'com.apollographql.android'

}

and also the dependency:

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

Trying to rebuild the project i get :

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

The graphql files are the ones from the official sample - GithuntFeedQuery.graphql and their schema.json, pasted in main folder.

Any ideas?

Answer 1

There are two solutions which I came accross while researching this problem:

1. Remove apollo from your project, (by editing your gradle files) clean your project, and add apollo again.

2. Try changing the apollo version in your project gradle file, ie. mine worked with

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

and it was 0.3.2 originally.

Answer 2

Had the same issue with prodRelease config, fixed by renaming prod flavor. In apps build.gradle I have:

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

which gives me 6 buildVariants

devDebug
devRelease
stageDebug
stageRelease
prodDebug
prodRelease

top 5 were building without a problems locally and on CI, while prodRelease was giving me the same error as you described without any logical explanation. GraphQL files are the same for dev, stage and prod... I've tried to create specific folders for "prod" then for "prodRelease", checked their access rights - all the same for all variants, nothing helped. And prodDebug were building correctly all the time. Then I've renamed prod flavor(don't forget to rename graphql files folder accordingly) and it now works like a charm.
