Crate java_manager 

Java Manager Library

A comprehensive Rust library for discovering, managing, and interacting with Java installations.

This library provides functionality to:

• Locate Java installations across different platforms
• Extract detailed information about Java installations
• Execute Java commands and capture output
• Manage multiple Java installations
• Search for files within Java installations

Features

• Cross-platform support: Works on Windows, macOS, and Linux/Unix
• Comprehensive Java detection: Finds Java installations in common locations
• Detailed Java information: Extracts version, architecture, supplier information
• Advanced searching: Wildcard support for file searches
• Command execution: Execute Java commands and capture output

Quick Start

use java_manager;

fn main() -> java_manager::Result<()> {
    // Get detailed information about the default Java installation
    let java_info = java_manager::get_local_java_home()?;
    println!("Default Java: {}", java_info);

    // Find all Java installations on the system
    let installations = java_manager::find_all_java_installations()?;
    println!("Found {} Java installations", installations.len());

    // Execute a Java command
    let output = java_info.execute_with_output(&["-version"])?;
    println!("Java version output:\n{}", output);

    Ok(())
}
