commit 3e90c47c140fa47f68f080d72d1c83a8449150a9
Author: Lukasz Lenart <[email protected]>
AuthorDate: Wed Apr 8 06:48:16 2026 +0200
feat(annotator): warn when Web facet is missing for Struts modules (#67)
Adds early feedback when a Struts-configured module has no WebFacet,
which prevents JSP result path resolution and Diagram navigation.
- WebFacetChecker: shared predicate reused by annotator and initializer
- StrutsWebFacetCheckingAnnotator: file-level warning on struts.xml with
quick action to open module facet settings
- StrutsFrameworkInitializer: one-time notification per affected module
on project open
- Struts2ProjectDescriptorBuilder.withoutWebFacet(): test support for
omitting WebFacet in light tests
Follow-up to PR #66 (DTD validation).
