About:
Fastjar is a high-performance implementation of Sun's jar utility, designed for creating and managing Java Archive (JAR) files. It serves as a faster, open-source alternative to the standard jar tool, optimizing the packaging process for Java applications. This tool is particularly useful for developers looking to speed up their build times.
Key Features:
  • High-speed JAR file creation and extraction
  • Command-line interface compatible with standard jar usage
  • Written in C for native performance
  • Lightweight and efficient resource usage
Use Cases:
  • Accelerating build processes in Java development environments
  • Packaging Java applications and libraries for distribution
  • Automating JAR creation in CI/CD pipelines
Alternatives:
  • jar (OpenJDK) – The standard tool included with the JDK; fastjar is often significantly faster for large archives.
