java-lint

library0.3.0jsnpmunverified

A Java lint utility library focused on removing unused imports. Current version 0.3.0 ships TypeScript types and requires Node.js ^18.13.0 || >=20.2.0. It uses java-parser for AST parsing. The package has been superseded by eslint-plugin-java-lang starting at v0.4.0, which converts the project into an ESLint plugin format. Key differentiators: lightweight, focused only on unused import removal, but with caveats about false negatives due to lazy global identifier collection.
