kafka-gitopts via homebrew : look for java in JAVA_HOME ?

[karawitan]

Hello,

Looks like the kafka-gitops depends on openjdk;
But kafka-gitops should not point at a specific java version;
Maybe you can use JAVA_HOME, as defined by homebrew ?

brew install kafka-gitops
Running `brew update --auto-update`...

@karawitan As you can see in the output you've posted, your JAVA_HOME environment variable is incorrect.

m1:~ kalou$ echo $JAVA_HOME
/opt/homebrew/Cellar/openjdk/19

m1:~ kalou$ brew list | grep jdk
openjdk
m1:~ kalou$ ls -ld /opt/homebrew/Cellar/openjdk/*/bin
drwxr-xr-x  31 kalou  staff  992 Sep 13 16:16 /opt/homebrew/Cellar/openjdk/19.0.1/bin

After setting JAVA_HOME to the correct directory (/opt/homebrew/Cellar/openjdk/19.0.1), it should work.

If the JAVA_HOME environment variable does not exist, it should work as long as java is on your PATH.
