OSS Licences Plugin fails with Gradle 8.8

[jakob-grabner]

Describe the bug
After updating to Gradle 8.8 the OssLicensesTask fails to resolve module variants.

Execution failed for task ':running:googleDevelopmentReleaseOssLicensesTask'.

The consumer was configured to find a library for use during runtime, preferably optimized for Android, as well as attribute 'com.android.build.api.attributes.AgpVersionAttr' with value '8.4.2', attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'release', attribute 'com.android.build.api.attributes.ProductFlavor:environment' with value 'development', attribute 'com.android.build.api.attributes.ProductFlavor:market' with value 'google', attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm'. However we cannot choose between the following variants of project :partner-accounts:partner-accounts:
- Configuration ':partner-accounts:partner-accounts:releaseRuntimeElements' variant android-aar-metadata declares a library for use during runtime, preferably optimized for Android, as well as attribute 'com.android.build.api.attributes.AgpVersionAttr' with value '8.4.2', attribute 'com.android.build.api.attributes.BuildTypeAttr' with value 'release', attribute 'org.jetbrains.kotlin.platform.type' with value 'androidJvm':
- Unmatched attributes:
- Doesn't say anything about com.android.build.api.attributes.ProductFlavor:environment (required 'development')
- Doesn't say anything about com.android.build.api.attributes.ProductFlavor:market (required 'google')
- Provides attribute 'artifactType' with value 'android-aar-metadata' but the consumer didn't ask for it
- Provides attribute 'com.android.build.gradle.internal.attributes.VariantAttr' with value 'release' but the consumer didn't ask for it

To Reproduce
Steps to reproduce the behavior:
Update Gradle to 8.8

Desktop (please complete the following information):

• Gradle version: 8.8
• Android Studio version: Android Studio Koala
• Plugin name and version: com.google.android.gms.oss-licenses-plugin" version "0.10.6"

Additional context
Everything works if I downgrade to gradle 8.7

+1. also with Android Studio Jellyfish

This is a blocker for us as well, it fails on release variant of a module. We cannot downgrade the Gradle version at the moment. Please let us know if there is a plan on fixing this? Thanks

Consider migrating to https://github.com/cashapp/licensee.

Thanks for the tip @Goooler I had a quick look but licensee does not look like a replacement. IT seems to do something different.

You can use the generated JSON file and parse info to show license page like chrisbanes/tivi#1471.

This unfortunately means that this plugin is now incompatible with the latest stable android gradle plugin (8.7) which requires a minimum gradle version of 8.9.

To my amazement it seems to work with the new versions in the Now in Android app. At least I could compile the project with the release build type. It still does not work for my project though (because of this issue)

@alixwar that project might not use productFlavors — I didn't notice any on a cursory glance at their build.gradle files

I am stuck with the same problem any one found the fix ?

You can consider migrating to a third-party library https://github.com/mikepenz/AboutLibraries which is well maintained and provides the same functionality

I moved on to use a 3rd party library, https://github.com/cashapp/licensee

This librarys primary purpose is to validate licenses, so not exactly a clean migration from Google OSS Licenses plugin. But you can add JSON parsing and a custom UI as was done for the Tivi app: https://github.com/chrisbanes/tivi/pull/1528/files

Task :app:freeReleaseOssLicensesTask of type com.google.android.gms.oss.licenses.plugin.LicensesTask: invocation of 'Task.project' at execution time is unsupported.

There is an easy way to bundle the artifacts.json for you, see https://github.com/cashapp/licensee/releases/tag/1.13.0.
