When trying to build my app module via terminal the build fails with error:

Configuration cache state could not be cached: field `provider` of `org.gradle.configurationcache.serialization.codecs.ProviderBackedFileCollectionSpec` bean found in field `__sourceDirs__` of task `:myapp:generateSentryBundleIdMinApi29Debug` of type `io.sentry.android.gradle.sourcecontext.GenerateBundleIdTask`: error writing value of type 'org.gradle.api.internal.provider.BiProvider'

Using --no-configuration-cache works.

The underlying issue seems to be that we want to package the BuildConfig, before it's even created. Let's have a closer look and check if maybe even should exclude the BuildConfig class.

hey @WebTiger89 the issue has been addressed in the version 4.6.0, which just has been published. Please give it a try and let us know. Thank you!

Unfortunately the issue persists. I have updated the version to 4.7.1. When enabling confiuration cache in gradle.properties file: org.gradle.unsafe.configuration-cache=true I get following error:

• What went wrong: Configuration cache state could not be cached: field provider of org.gradle.configurationcache.serialization.codecs.ProviderBackedFileCollectionSpec bean found in field __sourceDirs__ of task :myapp:generateSentryBundleIdMinApi29Debug of type io.sentry.android.gradle.sourcecontext.GenerateBundleIdTask: error writing value of type 'org.gradle.api.internal.provider.BiProvider' Querying the mapped value of property(org.gradle.api.file.Directory, property(org.gradle.api.file.Directory, property(org.gradle.api.file.Directory, map(org.gradle.api.file.Directory flatmap(provider(task 'generateMinApi29DebugBuildConfig', class com.android.build.gradle.tasks.GenerateBuildConfig)) check-type())))) before task ':myapp:generateMinApi29DebugBuildConfig' has completed is not supported

Using .\gradlew myapp:assembleMinApi29Debug --no-configuration-cache works

@romtsn Can you reopen the issue please

[romtsn]

@WebTiger89 ok, thanks for letting us know. In this case I'll have to ask to provide a reproducible sample - would you be able to do so? Otherwise, I'm afraid we won't be able to fix it.

[romtsn]

@WebTiger89 any chance you can provide a sample here?

[WebTiger89]

@romtsn I have found a solution: Since AGP 8.0 BuildConfig generation is disabled by default, see https://developer.android.com/build/releases/past-releases/agp-8-0-0-release-notes, BuildConfig generation must be enabled explicitly per module.

I have enbaled generation buildFeatures.buildConfig = true (build.gradle.kts)

for my android app module which is the cause for failing when sentry-android-gradle-plugin is used in combination with org.gradle.unsafe.configuration-cache=true (gradle.properties)

It works if I set buildFeatures.buildConfig = false, but it also works if I add android.enableBuildConfigAsBytecode=true to gradle.properties file, found here https://medium.com/androiddevelopers/5-ways-to-prepare-your-app-build-for-android-studio-flamingo-release-da34616bb946

[romtsn]

Glad that you found it and thanks for sharing the details!

I'd guess to reproduce this, we'd have to test on AGP 8.+ and enable buildFeatures.buildConfig = true, correct?

[WebTiger89]

Yeah buildFeatures.buildConfig = true and org.gradle.unsafe.configuration-cache=true (gradle.properties)

[romtsn]

okay, thanks, somehow I wasn't able to reproduce it myself, but one of our tests was able to catch this, so I'll look into it!

[romtsn]

@WebTiger89 version 4.9.0 has been shipped, please give it a try and let us know if the issue is still not fixed. thank you!
