Errors

joshprogrammer

Hello. I've been playing TripleA for several months now and really enjoy it. I've never had problems on my MX linux machine with the game before, but for some reason when I download the game .sh file from the website and install it, then go to open the game in my menu, it just sits there doing nothing while the TripleA logo is on my screen. I did a little investigation by going to my /opt/TripleA folder and opening in terminal, then typing ./TripleA to run the file directly from the terminal. That's when this error came up:

java.lang.ClassNotFoundException: org.triplea.game.client.HeadedGameRunner

I have a little programming experience but none with Java, so I'm practically clueless.
Any help is appreciated! Thanks in advance.

Hi @joshprogrammer

Welcome to the site !

What version are you on ? I think a recent fix may have had this happen to me as well but then was fixed quickly by @Myrd . Idk tho. Could be something different.

I'm on linux running ubuntu and it works for me. 2.6+14586

You may want to file a bug report at git.

Myrd

What version of Java do you have installed?

I think someone else reported that for some reason the Linux TripleA version may not be running with a bundled java, like it does on other platforms, but with whatever you have on your system, which can have problems if there's a mismatch.

What does java -version say on the command line? And what version of TripleA?

Also, if you download the triplea-game-headed.zip version and run java -jar <path to .jar file in the bin folder of the zip>, does that run into the same problem?

@myrd I cannot access the 2.6 version download - both the download version and the latest source code release are for version 2.5.22294. Where can I find a download for a newer version? And I did check, my computer is running Java 17.09.

@joshprogrammer yea i think you need java 21. Here's prerelease https://github.com/triplea-game/triplea/releases/

there was a thread not too long ago about this i think. I'll see if i can find it

Edit

so java 19 it looks like. I think those guys were having trouble with 21. Idk. You'd have to read the whole thread.

@beelee Thanks so much for the link! I downloaded the .sh file and installed it to my system. Version 2.6 runs fine! It came up with an error when I clicked on the button to download maps, but this isn't a big deal since I can download them manually - at least the game is playable now. If that more issues turn up I can report them.
Anyway, thanks so much for your help!
