Improved ESLint Checkstyle Formatter
JSON →An enhanced ESLint formatter that outputs Checkstyle-compatible XML, primarily for use with the Jenkins Checkstyle Plugin. Version 0.2.0 is the latest stable release. It allows optional tweaking of file paths via environment variables (CHECKSTYLE_OLD_PROJECT_DIR and CHECKSTYLE_NEW_PROJECT_DIR) to produce relative paths instead of absolute paths in CI environments. Unlike ESLint's built-in checkstyle formatter, this one supports path manipulation for Jenkins integration. The package is unmaintained since 2015 and serves a niche use case.
