Running .pkg on MAC OS from java code

Question

Am trying to run a .mpkg application from my java code :

public void runNewPkg(){

try {

           String command = \"sudo installer -pkg Snip.mpkg -target /App         


        

Answer 1

You can provide the password to sudo:

echo "p@sw0rd" | sudo -S cal -y 2011

The command above runs 'cal -y 2011' with root permissions.

If you want an interactive solution for elevating privilege, I have used openscript to elevate privilege of a wrapped shell script. It goes something like this:

import java.io.File;
import java.text.MessageFormat;

/**
 * OsxExecutor.java
 */
public class OsxExecutor {

    private String error = null;
    private String output = null;

    /**
     * Privileged script template format string.
     * Format Arguments:
     * <ul>
     * <li> 0 = command
     * <li> 1 = optional with clause
     * </ul>
     */
    private final static String APPLESCRIPT_TEMPLATE = 
        "osascript -e ''try''"
        + " -e ''do shell script \"{0}\" {1}''" 
        + " -e ''return \"Success\"''" 
        + " -e ''on error the error_message number the error_number'' "
        + " -e ''return \"Error: \" & error_message''"
        + " -e ''end try'';";


    public void executeCommand(String command, boolean withPriviledge) {
        String script = MessageFormat.format(APPLESCRIPT_TEMPLATE,
                                             command,
                                             withPriviledge
                                              ?  "with administrator privileges"
                                               : "");
        File scriptFile = null;
        try {
            scriptFile = createTmpScript(script);
            if (scriptFile == null) {
                return;
            }
            // run script
            Process p = Runtime.getRuntime().exec(scriptFile.getAbsolutePath());

            StreamReader outputReader = new StreamReader(p.getInputStream());
            outputReader.start();
            StreamReader errorReader = new StreamReader(p.getErrorStream());
            errorReader.start();

            int result = p.waitFor();

            this.output = outputReader.getString();
            if (result != 0) {
                this.error = "Unable to run script " 
                    + (withPriviledge ? "with administrator privileges" : "") 
                    + "\n" + script + "\n"
                        + "Failed with exit code: " + result
                        + "\nError output: " + errorReader.getString();
                return;
            }
        } catch (Throwable e) {
            this.error = "Unable to run script:\n" + script
                    + "\nScript execution "
                    + (withPriviledge ? " with administrator privileges" : "") 
                    + " failed: " + e.getMessage();
        } finally {
            if (scriptFile.exists()) {
                scriptFile.delete();
            }
        }
    }
}

If withPriviledge flag is true, a password dialog will be raised. Not shown is createTmpScript() which creates an executable file in /tmp, and StreamReader which extends Thread and is used to capture both stdout and stderr streams.

I would actually try editing your /etc/sudoers file to not prompt for a password. If you use the NOPASSWD tag, you should be able to do that. An example entry would be:

sumitghosh3 ALL=(ALL) NOPASSWD: ALL
