From 71166157544ac38adfca8678e064a936725a685e Mon Sep 17 00:00:00 2001 From: Gerd Aschemann Date: Mon, 13 Oct 2025 22:00:00 +0200 Subject: [PATCH 1/4] #405 Fix JUnit report filename length error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implement hierarchical directory structure for JUnit XML reports to solve filename length issues when checking HTML files in deeply nested directories. Changes: - Modify JUnitXmlReporter to create directory hierarchies mirroring source file structure instead of encoding paths into flat filenames - Add path normalization and security checks to prevent directory traversal - Update JUnitXmlReporterTest with 7 comprehensive tests for hierarchical structure, including edge cases for long paths and relative references - Add helper method findFirstXmlFile() for recursive XML file discovery - Fix tearDown() to handle directories when traversing file tree - Add AsciiDoc documentation in issue-405.adoc with code includes via tags - Update CLAUDE.md with AsciiDoc and commit message conventions - Add source code tags to JUnitXmlReporter.java for documentation includes The solution keeps individual filenames under OS limits while preserving full path information through directory structure. All 379 existing tests continue to pass.
