Slipstream mod manager can't find java after installing `brew install openjdk`, what should I do?

Today I freshly installed Bazzite on my computer to try the following tutorial. I was advised here (https://discordapp.com/channels/1072614816579063828/1282667481936298015/1282693482816864319) to install java with this command. I ran brew install openjdk, brew install openjdk@21 and brew install openjdk@17, and followed this tutorial (https://tinyurl.com/FTLmultiverse). At step 24, I got the output shown on the attached screenshot. I tried brew uninstall openjdk@21 and brew uninstall openjdk@17 if the multiple versions was the issue, but same output. I tried previously the same on Bazzite (see linked discord thread), and I got through step 24 (and instead got stuck at step 39). What should I do?

Solution:

try running the script manually from the terminal

can you run java in a terminal?

MaxiOP•2mo ago

Yes, outputted a long usage manual.

termdisc•2mo ago

can you run command -v java?

MaxiOP•2mo ago

Yes, outputted /home/linuxbrew/.linuxbrew/bin/java. When inserted into the bottom-left corner start menu and ran, it seemingly loads something (cursor animation shows up) but nothing shows up.

I can tell you what the script is attempting to do but not why it's failing

# Search in $PATH among other places.
java_cmd=$(command -v java);

# OSX uses a command to decide java's location (or prompt the user to install it).
if [ -x "/usr/libexec/java_home" ]; then
  export JAVA_HOME=$(/usr/libexec/java_home --request)

  if [ -n "${JAVA_HOME}" ]; then
    java_cmd=${JAVA_HOME}/bin/java
  fi
fi

if [ -n "${java_cmd}" ]; then

  echo "";
  echo "Found java at: ${java_cmd}";
  echo "";

  "${java_cmd}" -jar modman.jar;

else

  echo "";
  echo "This script was unable to find java."
  echo "";

fi

# Search in $PATH among other places.
java_cmd=$(command -v java);

# OSX uses a command to decide java's location (or prompt the user to install it).
if [ -x "/usr/libexec/java_home" ]; then
  export JAVA_HOME=$(/usr/libexec/java_home --request)

  if [ -n "${JAVA_HOME}" ]; then
    java_cmd=${JAVA_HOME}/bin/java
  fi
fi

if [ -n "${java_cmd}" ]; then

  echo "";
  echo "Found java at: ${java_cmd}";
  echo "";

  "${java_cmd}" -jar modman.jar;

else

  echo "";
  echo "This script was unable to find java."
  echo "";

fi

this is the code that deals with finding java

java_cmd=$(command -v java);

This is essentially what I had you run last but assigned to a variable

if [ -n "${java_cmd}" ]; then

This verifies if the variable exists, i.e., is nonzero that shouldn't be failing but appears to be doing so maybe it's a permissions thing as in the script can't reach into /home/linuxbrew

If it matters, I tried it on Fedora KDE spin and it worked as expected at this step (and instead got stuck at step 39, green play button turns to blue for a few seconds as it would start, and then reverts back to green without opening anything), and on Nobara it worked fully and was able to run the program after some tries, but during (everyday) usage I got frequent and random desktop envoirment restart crashes. It opened the GUI and worked as expected. I followed the other steps, and got stuck again at step 39. Because this issue is beyond the post's original thing, I'll mark this comment as an answer, thank you for helping! Do you have recommendations about what to do regarding the non-starting Steam game issue?
