MSCS unable to find installed java

[TraumaER]

I've installed java 19 via SDKMan and am able to see and use it, but mscs tells me that Java is not found.

Error:

➜  mscs git:(main) mscs list
ERROR: Java not found!
Try installing this with:
sudo apt-get install default-jre

I've got the same setup, mscs + sdkman installed java only, on a raspberry pi that is working. However for some reason on my Ubuntu server desktop mscs is unable to find java.

I edited mscs and msctl to print out the PATH variable and it shows the bin directory where java is located at, but it's still unable to find it.

mscs path -- /home/traumaer/.sdkman/candidates/java/19-amzn/bin:/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
msctl path -- /home/traumaer/.sdkman/candidates/java/19-amzn/bin:/home/linuxbrew/.linuxbrew/bin:/home/linuxbrew/.linuxbrew/sbin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
ERROR: Java not found!
Try installing this with:
sudo apt-get install default-jre

If I follow the suggestion of sudo apt-get install default-jre it is able to find java. However, it'll only ever use Java 11 that is installed that way and not use my Java 19.

Any help would be greatly appreciated.

Derp, So apparently Ubuntu is a little more Security conscious than PiOS. The reason why mscs was unable to see java even though the directory was on the PATH is because it was in my home directory and it didn't have permission.

Solution: Uninstall sdkman from my user home directory and install it under /usr/local/sdkman this gave the minecraft user the ability to see it.

Glad you got it figured out
