Walkthrough

This PR modernizes a Kotlin/Android project with major toolchain upgrades: JDK 11→17, Gradle 7.4→8.5, Android Gradle Plugin 4.1.3→8.1.0, Kotlin 1.6.10→1.9.0, and Android SDK targets 31→34. AndroidX, coroutines, Room, and test dependencies are upgraded, with one test behavioral change reflecting modified API fallback logic.

Changes

Cohort / File(s) Summary
CI/Workflow Configuration
.github/workflows/ci.yml, .github/workflows/testing.yml
Updated CI workflows to use JDK 17 instead of JDK 11; step names and java-version values updated accordingly; no other control flow changes.
Gradle Build System
build.gradle
Bumped Kotlin from 1.6.10 to 1.9.0, Hilt from 2.35 to 2.48, and Android Gradle Plugin from 4.1.3 to 8.1.0.
App Build Configuration
app/build.gradle
Updated compileSdk/targetSdkVersion to 34 (from 31/30.0.3); migrated Java compatibility from 1.8 to 17; upgraded AndroidX core, appcompat, material, constraintlayout, Fragment, Activity, ViewModel, LiveData, coroutines (1.6.0→1.7.3), Room (→2.6.1), and test dependencies (junit, mockk, core-testing, espresso). Added namespace block.
Gradle Wrapper & Runtime
gradle/wrapper/gradle-wrapper.properties, gradlew
Updated Gradle distribution from 7.4-bin.zip to 8.5-bin.zip; added networkTimeout=10000 and validateDistributionUrl=true. Enhanced gradlew shell script with improved error handling, MAX_FD guards, xargs availability checks, and safer Java detection via command -v instead of which.
JVM Arguments & Properties
gradle.properties
Added extensive --add-opens VM arguments for reflection access (java.base, java.desktop, jdk.compiler) in org.gradle.jvmargs; minor comment fix (corrected escaped apostrophe).
Test Behavior Change
app/src/test/java/com/cursokotlin/mvvmexample/domain/GetQuotesUseCaseTest.kt
First test modified: now expects zero invocations of quoteRepository.getAllQuotesFromDatabase() when API returns nothing (previously expected one invocation); reflects changed fallback behavior.
Local Environment
local.properties
Updated timestamp and SDK path from Unix (/Users/aris/Library/Android/sdk) to Windows (C\:\\Users\\Administrador\\AppData\\Local\\Android\\Sdk).

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20–25 minutes

Rationale: The majority of changes are homogeneous dependency updates across build.gradle and app/build.gradle, which reduces per-file cognitive load despite broad file spread. Gradle configuration changes (wrapper, properties, shell script) are non-trivial but well-scoped. The single test behavioral change requires understanding the implementation context, and local environment file updates are trivial. No deep logic analysis needed for most updates.

Poem

🐰 Hoppy times, the toolchain's spry,
Java 17 reaches for the sky!
Gradle eight hops swiftly along,
AndroidX joins the stronger throng.
With xargs guarding each graceful bound,
Our build now soars without a sound! 🚀

Title Check ❓ Inconclusive The title "Ci testing Ejemplo :(" is vague and lacks clarity about the actual changes in the pull request. While the changeset includes CI workflow updates (which justifies mentioning "Ci"), the primary scope encompasses much broader changes including major version upgrades for Java (11 to 17), Android SDK (31 to 34), Gradle (7.4 to 8.5), Kotlin (1.6.10 to 1.9.0), and numerous dependency updates. The title includes non-descriptive and unprofessional elements ("Ejemplo" and ":(" emoticon) that don't convey meaningful information about the actual changes, making it difficult for teammates scanning the history to understand the true scope of this modernization effort. Consider revising the title to clearly reflect the main purpose of these changes, such as "Upgrade build tools and dependencies (JDK 17, Android SDK 34, Gradle 8.5)" or "Modernize project toolchain and dependencies". This would provide teammates with a clear understanding of the scope and intent without vague or non-descriptive elements.

app/src/test/java/com/cursokotlin/mvvmexample/domain/GetQuotesUseCaseTest.kt (1)

26-36: Test expectation contradicts implementation – test will fail.

The test's line 35 changed from coVerify(exactly = 1) to coVerify(exactly = 0), but this contradicts the actual GetQuotesUseCase implementation.

The implementation explicitly calls repository.getAllQuotesFromDatabase() in the else branch when the API returns empty—yet the test now expects this method to be called zero times. This mismatch will cause the test to fail.

Correct this by either:

  1. Revert line 35 back to coVerify(exactly = 1) to match the actual behavior, or
  2. Update the implementation to remove the database fallback (delete the else clause)

Additionally, align the test name with the actual behavior. Currently it states "get values from database" but expects zero database calls.

local.properties (1)

1-8: Critical: Remove local.properties from version control.

The file header explicitly states this file "must NOT be checked into Version Control Systems" (Line 1-2). This file contains machine-specific paths and should be in .gitignore instead.

Apply this fix:

  1. Add local.properties to .gitignore
  2. Remove it from the repository:
git rm --cached local.properties

🔇 Additional comments (13)
gradle/wrapper/gradle-wrapper.properties (1)

3-5: LGTM! Gradle wrapper upgraded to 8.5 with good defaults.

The upgrade from Gradle 7.4 to 8.5 is well-configured. The addition of networkTimeout and validateDistributionUrl are good practices for reliability and security.

gradle.properties (2)

9-9: LGTM! JVM args expanded for Java 17 compatibility.

The extensive --add-opens flags are necessary for Gradle and Android tooling to work with Java 17's module system. These open internal JDK packages to unnamed modules, which is a common requirement when upgrading to Java 17.


15-15: LGTM! Comment typo fixed.

The apostrophe correction improves readability.

.github/workflows/ci.yml (1)

5-7: LGTM! Branch configuration reformatted.

The compact array syntax is functionally equivalent and more concise.

app/build.gradle (6)

9-9: LGTM! Namespace declaration added.

The namespace declaration is required by Android Gradle Plugin 8.x and properly configured.


29-30: LGTM! Java version upgraded to 17.

The Java compatibility settings are correctly aligned with the project-wide Java 17 migration.

Also applies to: 34-34


45-48: LGTM! Core dependencies modernized.

The AndroidX, coroutines, and lifecycle dependency updates are appropriate for the AGP 8.x and Kotlin 1.9 upgrade.

Also applies to: 51-57, 62-62


70-75: LGTM! Test dependencies updated.

The test dependency upgrades (JUnit, MockK, coroutines-test, AndroidX test) align with the project modernization.


67-68: Let me verify the database schema structure and check for any migration strategies or fallback configurations:

Now let me check the database builder configuration and look for any migration strategies or schema export:

Let me examine the QuoteDatabase file and the build.gradle configuration more closely to verify the current setup:

Based on my verification of the Room 2.6.1 migration requirements and the codebase, here is the rewritten review comment:


Room 2.6.1 update requires no migration for version 1 database.

Since exportSchema is true by default in Room, and your QuoteDatabase is at version 1 with no schema changes, migrations are not required. Room supports automated migrations in version 2.4.0-alpha01 and higher, making 2.6.1 fully compatible with your current setup.

No changes needed—the current implementation is compatible with Room 2.6.1.


10-10: No SDK 34 breaking changes apply to this app—verification complete.

The upgrade to SDK 34 is safe. The app doesn't implement foreground services, exact alarms, photo/media pickers, or full-screen intents—all features mentioned in the review comment that would require changes. The minimal AndroidManifest and MVVM codebase (Retrofit + Room) have no code patterns affected by SDK 34 restrictions. The app targets SDK 34 without requiring any modifications for the stated concerns.

gradlew (1)

58-58: LGTM! Gradle wrapper script updated to 8.5.

This is the standard Gradle 8.5 wrapper script with improved:

  • POSIX shell compatibility (Lines 147-159)
  • Java detection using command -v instead of which (Lines 134-140)
  • Better error handling and validation (Lines 217-221)
  • Default JVM options handling (Lines 202-203)

These are generated changes and should not be manually modified.

Also applies to: 83-87, 134-140, 147-159, 202-221

build.gradle (2)

10-10: AGP 8.1.0 migration verified—all critical requirements satisfied.

The namespace declaration at app/build.gradle line 9 is correctly implemented as namespace 'com.cursokotlin.mvvmexample'. Build configuration is compatible with AGP 8.1.0: Gradle wrapper is at 8.5 (compatible with AGP 8.x), Java 17 is set (sourceCompatibility/targetCompatibility), Kotlin 1.9.0 and Hilt 2.48 are both current versions, and buildFeatures are appropriately configured. All breaking changes from the AGP 4.x→8.1.0 migration have been addressed.


3-4: **No breaking changes detected—upgrade is safe. **

Verification complete across both major version upgrades:

Kotlin 1.6.10→1.9.0: The codebase avoids all identified breaking changes. The project is a standard Android app (not multiplatform), so the android { }androidTarget { } renaming does not apply. No usage of @JvmDefault, external enum, deprecated Volatile APIs, or K2 compiler was detected. AGP 8.1.0 is compatible with Kotlin 1.9.0.

Hilt 2.35→2.48: Verified standard Hilt patterns (@Module, @InstallIn(SingletonComponent), @Provides). No custom Dagger SPI plugins or wildcard generic bindings found. Project uses kapt, so KSP alpha issues do not apply.

All Kotlin language features and Hilt usage patterns in the codebase are compatible with the upgraded versions.
