myjar

myjar is a software project that facilitates the creation and management of Java Archive (JAR) files. JAR files are a package file format typically used to aggregate many Java class files and associated metadata and resources into one file for distribution. myjar aims to simplify the process of building these archives, allowing developers to specify which files should be included, how they should be organized, and what manifest information should be generated.

The project provides command-line tools and a programmatic API for interacting with JAR files. Users can define the contents of their JARs through configuration files or by directly specifying inclusion patterns. This flexibility enables the packaging of compiled Java code, resource files, and other necessary components for Java applications. myjar supports various options for creating executable JARs, which can be run directly using the Java Virtual Machine.

Beyond basic JAR creation, myjar also offers functionalities for updating existing JAR files, extracting their contents, and inspecting their internal structure. It is designed to be a lightweight and efficient utility, suitable for integration into build scripts and automated compilation processes. The project's goal is to provide a straightforward and reliable method for handling JAR packaging within the Java ecosystem.
