Description

This pull request removes the custom swagger-eclipse-transformer-maven-plugin module and all its related files from the project. Additionally, it cleans up dependencies and plugin configurations related to Jakarta artifacts and the transformer plugin in the BOM and integration test modules.

Key changes include:

Removal of the custom Maven plugin

• Deleted the entire swagger-eclipse-transformer-maven-plugin module, including its pom.xml, README.md, and main Java source file TransformMojo.java. This means the project no longer maintains a custom Eclipse Transformer Maven plugin.

Dependency and plugin cleanup

• Removed all Jakarta-related artifacts and the swagger-jaxrs2-servlet-initializer dependency from the BOM (swagger-bom/pom.xml) and its integration test (swagger-bom-integration-test/pom.xml). This reduces the number of managed and tested artifacts and simplifies dependency management.
• Removed the Maven Enforcer plugin configuration from the integration test module, as dependency convergence checks for mixed javax/Jakarta artifacts are no longer needed.

Minor cleanup

• Removed a comment header from the integration test POM for clarity.

Follow-up: #4991

Review details

Suppressed comments (2)

modules/swagger-project-jakarta/pom.xml:1

• Removing this module leaves CI/prepare-release.sh and CI/post-release.sh still executing cd modules/swagger-project-jakarta. Those directories no longer exist, so release versioning continues with failed path changes (and the following ../../mvnw commands run from the wrong directory). Remove or update those release-script steps in the same change.
  modules/swagger-project-jakarta/pom.xml:1
• This deletion removes the Jakarta artifacts and the transformer-generated swagger-maven-plugin-jakarta, but README.md still says the BOM manages both artifact families and lists the removed dependencies, while modules/swagger-maven-plugin/README.md still instructs users to use the Jakarta plugin. Those examples will no longer resolve for this project version; update the published documentation together with the artifact removal.
