Migrate dependency management to Gradle Version Catalog (libs.versions.toml)

[Copilot]

Replaces the bespoke buildSrc dependency constants (Versions.kt, Dependencies.kt, GroupedDependencies.kt, DependencyHandlerExtensions.kt) with a standard Gradle Version Catalog, enabling IDE auto-complete, Renovate/Dependabot version bump support, and a single canonical source for all dependency coordinates.

What changed

• New: gradle/libs.versions.toml — all versions, library GAVs, bundles (grouped deps), and plugin IDs in one TOML file
• Deleted: Versions.kt, Dependencies.kt, GroupedDependencies.kt, DependencyHandlerExtensions.kt from buildSrc
• Updated: buildSrc/.../ProjectConfigs.kt — removed Versions import; SDK/compiler versions now inlined as constants (they are build config, not dependency versions)
• Updated: app/build.gradle.kts + all 31 module build.gradle.kts files — replaced helper function calls with libs.* / libs.bundles.* accessors
• Updated: settings.gradle.kts — added enableFeaturePreview("TYPESAFE_PROJECT_ACCESSORS")

Before / After

// Before
import com.guru.composecookbook.build.dependencies.addComposeOfficialDependencies
import com.guru.composecookbook.build.dependencies.addNetworkingDependencies

dependencies {
    addComposeOfficialDependencies()
    addNetworkingDependencies()
}

// After
dependencies {
    implementation(libs.bundles.compose.official)
    implementation(libs.bundles.networking)
}

Bundles in the catalog mirror the old grouped dependency lists (e.g. compose-official, core-android, networking, third-party-ui), so call-site diffs are minimal. Convention plugins (common-compose-module-configs-script-plugin, common-kotlin-module-configs-script-plugin) are unchanged.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dl.google.com
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-opens=java.base/java.nio.charset=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED -Xmx4096M -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -cp /home/REDACTED/.gradle/wrapper/dists/gradle-8.5-bin/5t9huq95ubn472n8rpzujfbqh/gradle-8.5/lib/gradle-launcher-8.5.jar -javaagent:/home/REDACTED/.gradle/wrapper/dists/gradle-8.5-bin/5t9huq95ubn472n8rpzujfbqh/gradle-8.5/lib/agents/gradle-instrumentation-agent-8.5.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 8.5 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
