Hello @rashidi, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
This pull request introduces a new module for generating Liquibase changesets from Spring Data JDBC entities. This allows for automated database schema migration script creation based on the domain model. The changes include adding necessary dependencies, entity classes (Book, Author), repository interfaces, a test configuration using Testcontainers, and a test case to generate the Liquibase changeset. Additionally, the pull request includes documentation in README.adoc and a dedicated AsciiDoc page.
Highlights
- Module Initialization: Initializes the
data-jdbc-schema-generationmodule, providing functionality to generate Liquibase changesets. - Dependency Management: Adds dependencies for Spring Data JDBC, Liquibase, PostgreSQL, and Testcontainers to the module's
build.gradlefile. - Entity Definition: Defines
BookandAuthorentities with appropriate annotations for Spring Data JDBC, including@Table,@Id, and@MappedCollection. - Repository Interfaces: Creates
BookRepositoryandAuthorRepositoryinterfaces extendingCrudRepositoryto enable basic CRUD operations. - Test Configuration: Sets up a test configuration using Testcontainers to provide a PostgreSQL database for integration tests.
- Changeset Generation: Implements a test case (
BookRepositoryTests) that usesLiquibaseChangeSetWriterto generate a Liquibase changeset from the defined entities. - Documentation: Adds documentation in
README.adocand a dedicated AsciiDoc page (data-jdbc-schema-generation.adoc) explaining how to use the module.

Code Review
This pull request introduces a new module for generating Liquibase changesets from Spring Data JDBC entities. The changes include adding a new tutorial, updating the settings.gradle file, and creating the necessary source code and test files. Overall, the code is well-structured and the tutorial provides a clear explanation of how to use the new module. However, there are a few areas that could be improved.
Summary of Findings
- Missing License Headers: The new Java files in the
data-jdbc-schema-generationmodule are missing license headers. It's important to include these headers for legal and attribution purposes. While I am not making repeated comments on this, please ensure that all Java files have the appropriate license headers. - Inconsistent use of
@DataJdbcTestproperties: In theBookRepositoryTestsclass, thespring.liquibase.enabled=falseproperty is commented out. This inconsistency should be addressed to ensure the test behaves as expected. - README improvements: The README files could benefit from minor improvements in wording and formatting to enhance readability and clarity.
Merge Readiness
The pull request is almost ready for merging. However, the missing license headers and the inconsistency in the @DataJdbcTest properties should be addressed before merging. The README improvements are minor and can be addressed at the author's discretion. I am unable to approve the pull request, and recommend that others review and approve this code before merging.
