Inspects JAR file contents, searches for entries, and reads configuration files without extraction.
JAR Explorer provides a specialized set of tools for Claude Code to interact with Java Archive (JAR) files directly. It allows for listing internal directories, performing regex-based searches for specific entries, and reading non-class files like XML configs, property files, and manifests without the need to manually extract them to disk. This is particularly useful for debugging dependency configurations, verifying build outputs, and inspecting metadata in large enterprise Java projects where manual extraction is cumbersome or prone to cluttering the workspace.
Key Features
01Bypasses the need for manual extraction using unzip or jar xf commands.
02List all internal JAR entries and directory structures via a simple CLI.
030 GitHub stars
04Read raw file contents like properties and manifests directly from the JAR.
05Perform case-insensitive regex searches for specific filenames within archives.
06Safe, read-only operation optimized for Claude Code auto-approval hooks.
Use Cases
01Verifying MANIFEST.MF or spring.factories content to debug classpath and auto-configuration issues.
02Searching for specific resource files or configuration properties within deep dependency trees.
03Inspecting the contents of project build artifacts to ensure assets are correctly packaged.
