I am a perfectionist with more than thirty years of experience in all areas related to software development using emerging technologies. Since 2010 I have focused exclusively on the Android platform.

What happened?

After upgrading an Android project to Gradle 9 my CI build failed with the following error message:

Could not set unknown property 'archivesBaseName'
for project ':app' of type org.gradle.api.Project.

The cause

Culprit is the code in my app/build.gradle.kts file to change the filename of the generated APK/AAB files when building on a CI server.

android {
  defaultConfig {
    ...
    if (isBuildServer()) {
      setProperty("archivesBaseName", "$applicationId-$versionName-$versionCode")
    }
    ....
  }
}

It turns out the archivesBaseName property has been deprecated for quite a while and was finally removed in Gradle 9.0.0.

The solution

The Gradle 9.0.0 upgrade instructions are very cryptic but the solution is fairly simple. You can replace the above code with similar code that uses the base.archivesName property.

android {
  ...
}
base {
    if (isBuildServer()) {
        archivesName = "${android.defaultConfig.applicationId}-${android.defaultConfig.versionName}-${android.defaultConfig.versionCode}"
    }
}

Happy upgrading!
