Claude Execution Message

Claude finished running successfully.

Excellent! Everything compiles successfully. Now let me create a comprehensive summary of the migration:

Migration Complete!

I have successfully migrated the IntegrationSpec.groovy test base class to IntegrationTest.java. Here's what was accomplished:

Files Created/Modified:

1. New Test File: src/test/java/com/palantir/gradle/versions/IntegrationTest.java

   • Migrated from Groovy/Nebula framework to Java/JUnit 5 with Gradle TestKit
   • All three utility methods migrated: setup(), generateMavenRepo(), and runTasksWithConfigurationCache()

2. Modified Original: src/test/groovy/com/palantir/gradle/versions/IntegrationSpec.groovy

   • Added delineator comments for review comparison

3. HTML Diff: test-migration-notes/IntegrationTest.html (390 KB)

   • Side-by-side comparison of old and new files

4. Migration Notes: test-migration-errors.md

   • Documents all errors encountered and how they were resolved

5. Summary: MIGRATION_SUMMARY.md

   • Comprehensive overview of the migration

Key Migration Changes:

Framework Switch:

• From: Nebula IntegrationTestKitSpec (Groovy + Spock)
• To: Standard Gradle TestKit with JUnit 5 (Java)

Major Technical Changes:

1. Project Directory: Now uses @TempDir Path projectDir (JUnit 5 managed)
2. Setup Method: Uses @BeforeEach and Java NIO for file operations
3. Test Execution: Uses GradleRunner.create() instead of Nebula's createRunner()
4. Assertions: Migrated from Groovy assert to AssertJ assertThat()
5. Error Handling: Fixed ErrorProne issues (StreamResourceLeak, UncheckedIOException)

Compilation Status:

✅ All code compiles successfully with no errors or warnings

Notes:

• The delineator comments remain in the original Groovy file for review purposes
• They were removed from the new Java file after the HTML diff was generated
• The migration maintains functional equivalence with the original implementation
• All 8 integration test classes that extend this base class will need to be migrated separately

The HTML diff can be viewed at:
test-migration-notes/IntegrationTest.html
