Apollo-android: Kotlin & Java files being generated

[KyleDBoyd]

Hey all! Been using the library for awhile and loving it 💪

Summary
I recently tried to uptake the kotlin model generation.

apollo {
    setGenerateKotlinModels(true)
}

This works well, but it also generates the Java class which results in a duplicate class error.

Description
Queries and schema live in src/main/graphql/{package}/

Version
1.3.2

Did you try to clean, maybe it was left overs from previous build?

Yeah, I cleaned & delete the entire build directory in the module that contained the Java + Kotlin files 😕

[martinbonnin]

setGenerateKotlinModels(true)

I would not expect this to work on 1.3.2. I believe this changed to

generateKotlinModels.set(true)

Can you double check your plugin version matches the apollo-api version ?

Also can you share the structure of your build directory ? it should be something like

build/generated/source/apollo/debug/service

[KyleDBoyd]

@martinbonnin Thanks for the quick reply!

I did also try generateKotlinModels.set(true), but no luck there. According to the 1.3.x migration guide, this adjustment should only matter if you are using a .kts build file.

I've confirmed that my apollo-gradle-plugin is also 1.3.2.

My build directory is build/generated/source/apollo/debug/service/{package} as you described above. Within the package there are files (Java & Kotlin) for each graphql query file. There is also a type package with all of the generated ENUMs & inputs (Java & Kotlin).

Indeed, Groovy still allows setGenerateKotlinModels() 👍

Can you check the following?

• Only run one task: ./gradlew :module:generateDebugServiceApolloSources
• Disable caching: ./gradlew :module:generateDebugServiceApolloSources --no-build-cache

Happy Monday! It was a gradle cache issue 🤦‍♂ Thanks @martinbonnin !

I am still facing this issue.
apollo version: 1.4.3
gradle: 6.3

apollo { generateKotlinModels.set(true) }

[martinbonnin]

@sudansh can you try deleting your gradle directory (rm -rf ~/.gradle) and re-run your task with --no-build-cache ? Does it still happen ?

[sudansh]

thanks. this fixed it.
