Problem Description

Issue

the instance only keeps trying to update, but it wont try launching the .jar or even give me any kinda error.

Reproduction Steps

  • start instance
  • changed launch Args
  • set it to a download url instance
  • Fails to launch or do anything with the jar

Means either it is not downloading properly or you have not set the jar name/path properly so amp can’t find it

i have found further details after wiping the instance and making a new one, with standard values on everything i can successfully map a .jar to launch and can create errors in console. However when I change the settings to have a instance specific java version (java 8 LTS) the system enters the looping of download → update → nothing. When i remove the instance java it shows the the paths are working perfectly fine.

Can’t really troubleshoot without seeing what you have configured

im having a new issue of replicating it now lol, i had all the settings preconfigured before i spun it up but as soon as i disabled the the instance versioning of java the server launched with java 21 then i set the instance again and now it nots replicating. Probably something i did wrong.
