Fix duplicate jaxb-core dependency issue (#187)

[mlopezFC]

Fixes #187

This PR resolves the duplicate jaxb-core-4.0.6.jar dependency issue that prevented users from upgrading to version 2.5.x when building WAR files with Gradle. The problem occurred because both docx4j-JAXB-ReferenceImpl and docx4j-JAXB-MOXy transitively included different implementations of the same JAXB core library under different Maven group IDs (org.glassfish.jaxb:jaxb-core and com.sun.xml.bind:jaxb-core).

The fix adds a Maven exclusion to the docx4j-JAXB-MOXy dependency, excluding com.sun.xml.bind:jaxb-core while keeping the GlassFish reference implementation. This change has been verified with a clean dependency tree, successful build, all unit tests passing and also manual testing of the demo.

Walkthrough

This pull request adds two new entries (.eclipse and .vaadin) to .gitignore and adds a transitive dependency exclusion to pom.xml, excluding com.sun.xml.bind:jaxb-core from org.docx4j:docx4j-JAXB-MOXy to resolve duplicate jaxb-core implementations.

Changes

Cohort / File(s)	Summary
Build configuration pom.xml	Adds exclusion for com.sun.xml.bind:jaxb-core transitive dependency in org.docx4j:docx4j-JAXB-MOXy:11.5.0 to prevent duplicate jaxb-core artifacts
Git configuration .gitignore	Adds .eclipse and .vaadin to ignored file patterns

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• The .gitignore changes are trivial additions with no behavioral impact
• The pom.xml exclusion is a straightforward dependency configuration change addressing a known duplicate dependency issue
• No complex logic or multi-file structural changes involved

158-167: Based on my verification, I now have sufficient information to rewrite the review comment. Let me compile my findings:

Key Findings:

1. The exclusion of com.sun.xml.bind:jaxb-core from docx4j-JAXB-MOXy is syntactically correct XML
2. docx4j-JAXB-MOXy 11.5.0 uses Jakarta XML Binding 4.0 + EclipseLink MOXy, not old Oracle JAXB
3. docx4j-JAXB-ReferenceImpl 11.5.0 uses GlassFish JAXB (org.glassfish.jaxb:jaxb-runtime)
4. No evidence of test failures found in the repository
5. The exclusion appears to be a legitimate dependency management fix to prevent duplicate/conflicting JAXB implementations
6. MOXy should function correctly with the exclusion

Resolve the Review Comment

The exclusion is syntactically correct and logically sound for managing duplicate JAXB implementations.

The exclusion of com.sun.xml.bind:jaxb-core from docx4j-JAXB-MOXy (lines 158–167) is properly formatted Maven XML and represents a valid dependency management strategy. Both docx4j implementations now use Jakarta XML Binding 4.0: ReferenceImpl uses org.glassfish.jaxb:jaxb-runtime (modern), and MOXy uses EclipseLink MOXy runtime. The exclusion prevents a duplicate or conflicting JAXB core implementation and should not break functionality since MOXy itself does not depend on the legacy com.sun.xml.bind:jaxb-core artifact.

Tip

📝 Customizable high-level summaries are now available in beta!

You can now customize how CodeRabbit generates the high-level summary in your pull requests — including its content, structure, tone, and formatting.

• Provide your own instructions using the high_level_summary_instructions setting.
• Format the summary however you like (bullet lists, tables, multi-section layouts, contributor stats, etc.).
• Use high_level_summary_in_walkthrough to move the summary from the description to the walkthrough section.

Example instruction:

"Divide the high-level summary into five sections:

1. 📝 Description — Summarize the main change in 50–60 words, explaining what was done.
2. 📓 References — List relevant issues, discussions, documentation, or related PRs.
3. 📦 Dependencies & Requirements — Mention any new/updated dependencies, environment variable changes, or configuration updates.
4. 📊 Contributor Summary — Include a Markdown table showing contributions:
   | Contributor | Lines Added | Lines Removed | Files Changed |
5. ✔️ Additional Notes — Add any extra reviewer context.
   Keep each section concise (under 200 words) and use bullet or numbered lists for clarity."

Note: This feature is currently in beta for Pro-tier users, and pricing will be announced later.
