Problem of version when starting robocode with java

[Pierre-Yves]

Hi,

I have a project with robocode and java. There is a class to easily start robocode and test the robot in it. It is several years old and I successfully used it many times, but now, it stopped working. I have no idea why (it speaks about versions, I followed the log on github but that wasn't useful).
Could you help me ?

Here is the class that calls robocode :

package controller;

import java.io.IOException;

public class TestBattle {

    public static void main(String[] args) {
        String ROBOCODE_PATH = "libs/robocode.jar";
        String BATTLE_PATH = "data/test.battle";
        try {
            // Launch the test in Robocode
            Runtime.getRuntime().exec("java -Xmx512M -DNOSECURITY=true -DWORKINGDIRECTORY=data -cp "

                    + ROBOCODE_PATH + " robocode.Robocode -nosound -battle " + BATTLE_PATH).waitFor();
        } catch (IOException | InterruptedException e) {
            e.printStackTrace();
        }
    }

}

And here is the "main battle log" from Robocode :

Hi,

I believe this is due to a problem with the newest version of Robocode
(1.9.3.3). I fixed a problem with "java.lang.IllegalArgumentException: The
format of the version string is not a valid", which is currently available
in a beta version for the next version 1.9.3.4 coming out soon. In the
meanwhile, it is quite safe to use the beta available from here:
https://robocode.sourceforge.io/files/robocode-1.9.3.4-Beta-2-setup.jar

I expect that will work. :-)

Cheers,

• Flemming
