To view the full build log, open [`buildCommandOutput.log`](./buildCommandOutput.log) + +``` +The build log shows a successful Maven build for a Java 21 project. The compilation, resource processing, and testing phases completed without errors. One unit test was executed and passed successfully. +``` + + +### Q Generated Summary and Recommendations Scroll to top + + + #### Summary + Q has made the following changes during the transformation process. Please note that the summary is generated by GenAI. +1. **JUnit Migration**: Updated from JUnit 4 to JUnit Jupiter (JUnit 5). This involved changing import statements from `org.junit.Test` to `org.junit.jupiter.api.Test` and from `org.junit.Assert.assertEquals` to `org.junit.jupiter.api.Assertions.assertEquals` in `MathTest.java`. JUnit 5 provides better support for Java 8+ features and has a more modular architecture. +2. **BigDecimal Rounding Mode Update**: Replaced deprecated `BigDecimal.ROUND_*` constants with the `RoundingMode` enum in both `Math.java` and `MathTest.java`. For example, `BigDecimal.ROUND_DOWN` was replaced with `RoundingMode.DOWN`. This follows the Java recommendation to use the more type-safe enum introduced in Java 5. +3. **Boxed Primitive Constructors Replacement**: Replaced deprecated boxed primitive constructors (e.g., `new Boolean(true)`, `new Integer(1)`) with their corresponding factory methods (`Boolean.valueOf(true)`, `Integer.valueOf(1)`) in `Math.java`. This change follows best practices as these constructors have been deprecated since Java 9. +4. **Spring Boot Upgrade**: Updated Spring Boot from version `2.0.5.RELEASE` to `3.2.12` in the `pom.xml`. This is a major version upgrade that brings numerous improvements, security fixes, and compatibility with newer Java versions. +5. **Jakarta EE Migration**: Replaced `javax.validation` dependencies with `jakarta.validation` and updated the import statements in the code (e.g., changing from `javax.validation.Valid` to `jakarta.validation.Valid` in `MoviesController.java`). This reflects the migration from Java EE to Jakarta EE that occurred when the platform moved to the Eclipse Foundation. +6. **REST Controller Annotation Update**: Changed from using `@RequestMapping(method = POST)` to the more specific `@PostMapping` annotation in `MoviesController.java`. This follows Spring best practices by using the more concise and readable annotation. +7. **Dependencies Version Updates**: Updated several dependencies to their newer versions, including: + - `org.json:json` from `20200518` to `20240303` + - `org.apache.logging.log4j:log4j-api` and `log4j-core` from `2.13.3` to `2.23.1` + - Changed `mockito-all` to `mockito-core` and removed explicit version to use Spring Boot's managed version +8. **Maven Compiler Configuration**: Updated the Maven compiler plugin from `3.8.1` to `3.14.0` and changed from using `` and `` parameters to the more modern `` parameter, which better handles cross-compilation. +9. **Path Variable Simplification**: Simplified `@PathVariable("movieId") int movieId` to just `@PathVariable int movieId` in `MoviesController.java`, leveraging Spring's capability to infer the variable name when it matches the path parameter. + + #### Recommendations + Q was able to compile the upgraded app successfully. Here are detailed recommendations to further improve the upgrade. Please note that these recommendations are generated by GenAI, apply them accordingly. + + +1. Please review and accept the code changes using the diff viewer. If you are using a Private Repository, please ensure that updated dependencies are available. +2. If this project uses `Maven CheckStyle`, `Enforcer`, `FindBugs` or `SpotBugs plugins`, Q disabled these plugins when building the project to verify proposed upgrades. Please enable them and verify the code again. +3. To help transform the rest of your code, you can use Amazon Q chat in the IDE. You can ask Amazon Q to review the partially updated files and provide new code to address issues, such as compilation errors. You can also use features like `/dev` and `@workspace` to include more of your project as context and get suggestions for multiple files at a time. + + + +### Planned dependencies replaced Scroll to top + +Amazon Q updated the following dependencies that it identified in the transformation plan + +| Dependency | Action | Previous version in Java 8 | Current version in Java 21 | +|--------------|--------|--------|--------| + + +### Additional dependencies added Scroll to top + +Amazon Q updated the following additional dependencies during the upgrade + +| Dependency | Action | Previous version in Java 8 | Current version in Java 21 | +|--------------|--------|--------|--------| +| `jakarta.validation:jakarta.validation-api` | Added | - | 3.1.1 | +| `javax.validation:validation-api` | Removed | 2.0.1.Final | - | +| `junit:junit` | Removed | 4.13.1 | - | +| `org.apache.logging.log4j:log4j-api` | Updated | 2.13.3 | 2.23.1 | +| `org.apache.logging.log4j:log4j-core` | Updated | 2.13.3 | 2.23.1 | +| `org.apache.maven.plugins:maven-compiler-plugin` | Updated | 3.8.1 | 3.13.0 | +| `org.json:json` | Updated | 20200518 | 20240303 | +| `org.mockito:mockito-all` | Removed | 1.10.19 | - | +| `org.mockito:mockito-core` | Added | - | - | +| `org.springframework.boot:spring-boot-starter-parent` | Updated | 2.0.5.RELEASE | 3.2.12 | + +### Deprecated code replaced Scroll to top + +Amazon Q replaced the following instances of deprecated code.
