Function locate_java_home 

pub fn locate_java_home() -> Result<String>

Locates and returns the Java home directory path.

This function first checks the JAVA_HOME environment variable. If not set or empty, it attempts to locate Java using platform-specific methods.

Platform-specific Behavior

• Windows: Uses the where command to find java.exe
• macOS: Uses /usr/libexec/java_home system utility
• Linux/Unix: Uses the which command to find java

Returns

• Ok(String) containing the Java home path
• Err(JavaLocatorError) if Java cannot be located

Errors

This function may return an error if:

• Java is not installed
• Java is not in the system PATH
• The platform-specific command fails

Examples

use java_manager;

fn main() -> java_manager::Result<()> {
    let java_home = java_manager::locate_java_home()?;
    println!("Java home: {}", java_home);
    Ok(())
}
