Run As Root

A java library to run pieces of code as root using native root password input dialog.

A new JVM is created in every execution and destroyed after completion.

This library uses Out Process to create new JVMs.

Why use it?

• Ask user for credentials in Windows, Linux and macOS.
• Do privileged actions.
• Limit scope of root code execution.
• Upgrade permissions during runtime temporarily.

Usage

// Specify JVM options (optional)
RootExecutor rootExecutor = new RootExecutor("-Xmx64m");

// Execute privileged action without return
rootExecutor.run(() -> {
    // Call your admin code here.
}));

// Execute privileged action with return
Object value = rootExecutor.call(() -> {
    // Call your admin code with return here.
    return null;
}));
System.out.println(value);

Tips

• Init simple, after include this lib in your project just try to write a file in a protected folder to validate if it is working.
• Avoid big classpaths, it can be a problem in Windows. #8
