Multiple versions of Java installed.

[MintPlays]

Hello, I'm a complete noob when it comes to messing with Java and settings and such. I currently have two versions of Java on my PC, Java 8 and Java 18, with Java 18 being the default. Before I used MSCS, I would explicitly state in a .sh file the path to the java version I needed and would be able to run my server like normal. I am currently trying to mess with the mscs.properties file and thought I could do the same as before, using the mscs-server-command, and explicitly state the path to the Java I needed for the server version. However, after trying to run it, it keeps telling me "Java not found". I know the simple solution would probably be to just switch the default Java version, but I rather be able to run the servers seamlessly without changing it. How do I achieve this in mscs? Is there a config file or different settings I must change? Any response is appreciated, thank you.

In the mscs-server-command setting, you want to replace $JAVA with the full path to the version you want to use.

I'm not sure where the issue lies. I would try switching to the minecraft user

sudo su -s /bin/bash minecraft

then test java as the minecraft user

/opt/java/jdk-8/bin/java

If the minecraft user can access java, then the problem is elsewhere. I'm just not sure where

Ok so I made some progress, after just changing ONE thing, giving the bin folder itself o+x permissions, I can now use mscs commands again. Right now, I am in the bin directory as the minecraft user and attempting to do ./java -version but now I am seeing this error: ./java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory. I really appreciate y'alls help btw, I'm going to keep messing around and hopefully not mess it up more.

It might be fixed??? After being utterly defeated for a second, it seems to finally go live. I say that because after running the start command, literally seconds after it kicks this error at me: find: Failed to restore initial working directory: /home/mintplays: Permission denied No clue why it wanted to access my home directory, unless it needs to in order to access the other mscs files I had seen before. I tried changing something, then tried starting it again but it said "world already running" and was confused for a second. I confirm in status that it said the server was up, I launch minecraft and sure enough I can join the server. It seems the fix was just chmod o+x to all of the lib folder too.

Good. I'm glad you got it working.

I really appreciate y'alls help, I would definitely not have figured anything out without y'all. I've gone and tested the rest of the worlds I had imported and 3/4 are working. Last one doesn't work due to it having a very particular and complex start.sh file and I can't really get it to work with mscs. It's whatever though, overall everything else works as expected. Thank you all.
