Problem Description: So I am currently trying to run the newest version of Greg Tech New Horizons on my server and it wont run on any java version on the server nor a server I set up on my pc but one I updated my pc java to 25 it instantly work and im wondering how I can port a version of java 25 into my AMP server
If you're sharing console output, logs, or commands you have run, please make sure to use code tags
(3x backticks for blocks, 1x backtick for a single line) to help make posts readable. This also
provides syntax highlighting.
Actions taken to resolve so far: I have tried to open a Java install file on the server but in the end I could not figure it out
I have the same problem, java -version when logged in as amp shows that 25 is installed, but AMP only lists up to 21. I have restarted etc.
Any solution?
Is the instance in docker?
Yes it is - I can see temurin 8, 11, 17 and 21 as options in AMP, and java -version shows 25. But not 25 option in AMP
Click on the pencil icon on the instance tile and change the image to cubecoders/ampbase:java-lts
I stopped the instance, clicked pencil , and tried typing cubecoders/ampbase:java-lts in as the image (this was not one of the dropdown options), saved changed, started the instance, and Java 25 still did not show.
I repeated this, instead choosing cubecoders/ampbase:java from the dropdown. This didn’t work either.
I also tried both the above with a newly created test instance, and that didn’t work.
The java-lts image has 25. I know, I created it
The java image does not
java-lts does not appear in the dropdown menu.
I know, it hasn’t yet been integrated into AMP’s code (I don’t have access to that code)
Type it in
Sadly it doesn’t work. Java is installed and shows in debian via java -version. It does not show in AMP instances, even with java-lts typed in.
To add java 25 you should:
in Container settings - Container Packages press Add Package
type temurin-25-jdk
restart the instance
after that, you will be able to choose java 25 in minecraft settings
The right way is the way I posted originally, so that Java 25 does not have to be reinstalled every time the instance is started
Change the docker image to:
cubecoders/ampbase:java-lts
Sadly, neither works. I have tried both (and also adding the package and putting the lts image in container image).
My java -version shows:
Is docker even enabled for that instance?
Did you save changes?
What shows in the deployment log?
Yes, changes saved:
