My class is:

package ir.iais.activemq.salary;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * Hello world!
 */
public class ActiveMQMailApp {
    private static volatile int counter = 0;

    public static void main(String[] args) throws Exception {
        MailConsumer.initService();
        for (int i =0;i<11;i++) MailProducer.sendMail(fakeMail());
        System.out.println("counter is: " + counter++);
    }

    private static String fakeMail() throws InterruptedException {
        Thread.sleep(1000);
        SimpleDateFormat sdf = new SimpleDateFormat("YYYY-MM-dd  hh:mm:ss");
        return "<html><body><p>Date: <b> "+sdf.format(new Date())+" </b></p></body></html>";
    }

}

I also commented all body of main method but it still throw the same error.

ActiveMQMailApp class run with this command correctly:

 mvn exec:java -Dexec.mainClass="ir.iais.activemq.salary.ActiveMQMailApp"

Let me know your environment

|& is a bashism to redirect both stderr and stdout. Try it without &

If that works maybe we can find a posix solution or add both redirections as an feature option (redirect-both) or global option (no-posix)

albfan commented 8 years ago

Check this:

http://stackoverflow.com/a/16497456/848072

replace |& with 2>&1 | and it should work.

albfan commented 8 years ago

That was added for detect old java version, so I guess is fair to detect it with bash<4. |& was introduced on bash 4.

Feel free to reopen if it keeps failing, Thanks.

Hi @albfan. The first bug fixed, but the class cannot run yet. the error is this:

I added a line to mvnexec file to print out the maven command on line 2. I'm on Mac OS X 10.11.6 with jdk1.8.0_65 using Oh My ZSH in iTerm2 v3!

While running ActiveMQMailApp class has problem, another class in this project ( ir.iais.activemqtut.App) can be run nicely.

▶ mvnexec
1) ir.iais.activemqtut.App
2) ir.iais.activemqtut.salary.ActiveMQMailApp
#?

Body of ActiveMQMailApp is as same as before.

I bet MailConsumer.initService(); is crashing in some way. See it exits with a 1 value.

Maybe a try/catch on main method with a printStacktrace() would give you a hint of the problem.

If your code is avaliable would be interesting to see if there's something about plugin exec version configurable, because there's a problem with output flush prior to version 1.3.2 and you (and everybody I guess) use 1.2 version through mvnexec.
