JAVA_HOME not set on apple m1

[EeeMt]

jenv 0.5.4

I execute follow steps on my m1 MBA and intel MBP:

1. brew install jenv
2. echo eval "$(jenv init -)" >> /Users/xiquan/.zshrc
3. jenv add $(/usr/libexec/java_home)
4. jenv global 1.8
5. <open new terminal tab>
6. echo ${JAVA_HOME}

The intel MBP works fine while the m1 MBA not.

Environment info of the m1 MBA:

I was able to get this working by doing the following:

rm ~/Library/LaunchAgents/jenv-environment.plist
jenv macos-javahome

To view the file:

cat ~/Library/LaunchAgents/jenv-environment.plist
<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
 <plist version="1.0">
 <dict>
   <key>Label</key>
   <string>my.startup</string>
   <key>ProgramArguments</key>
   <array>
     <string>sh</string>
     <string>-c</string>
     <string>
     launchctl setenv JAVA_HOME /usr/local/opt/jenv/versions/11.0 ;
     </string>
   </array>
   <key>RunAtLoad</key>
   <true/>
 </dict>
 </plist>

Verify in a new shell:

interneuron:~ kito$ echo $JAVA_HOME
/usr/local/opt/jenv/versions/11.0

If you're using an IDE or another tool, you'll have to restart it. (This worked for me when using IntelliJ and spawning Maven).

I'm having the same issue,

~ ❯ jenv doctor                                                                                                                                                                                                                              ⏎

With the following being in my ~/.zshrc

# jenv
eval export PATH="/Users/<username>/.jenv/shims:${PATH}"
export JENV_SHELL=zsh
export JENV_LOADED=1
unset JAVA_HOME
source '/opt/homebrew/Cellar/jenv/0.5.4/libexec/libexec/../completions/jenv.zsh'
jenv rehash 2>/dev/null
jenv refresh-plugins
jenv() {
  typeset command
  command="$1"
  if [ "$#" -gt 0 ]; then
    shift
  fi

  case "$command" in
  enable-plugin|rehash|shell|shell-options)
    eval `jenv "sh-$command" "$@"`;;
  *)
    command jenv "$command" "$@";;
  esac
}

I didn't actually have the file /Library/LaunchAgents/jenv-environment.plist, and running jenv macos-javahome gives the following;

~ ❯ jenv macos-javahome

Exactly same issue on my MacBook Pro M1. Because of that Maven is using incorrect version of Java (I need it to pick up Java 11):

Same problem here on a M1 Mac.

Using Kotlin Multiplatform Build which runs from xCode with a run script.
I ended up editing ~/Library/LaunchAgents/jenv-environment.plist and manually setting JAVA_HOME to make the script working.

Got the same problem and I got it fixed by running: jenv rehash followed by a exec $SHELL -l. Hope it helps someone.

[jebeaudet]

For me, I fixed it just by running jenv enable-plugin export and by restarting my shell. Hopefully it helps someone

Same issue jenv: version `ibm64-1.8.0.302' is not installed

I was having the same problem here, but not with a GUI application so I knew ~/LibraryLaunchAgents/jenv-environment.plist wasn't the problem. For me, jenv wasn't setting JAVA_HOME in the shell, either on startup or when changing to a directory containing a local .java-version file. I checked that jenv was being initialized in my startup scripts, that the export plugin was enabled, and that jenv javahome was reporting the correct directory, but I still had no JAVA_* or JDK_* environment variables.

After banging my head against the wall for way too long, I finally figured out that the init-caching I use in my shell configuration had cached the jenv init - statements before I enabled the export plugin. Even though jenv itself was getting initialized, the line that should have source'd the export hook function was missing. After updating the cached init to include the proper export plugin initialization, everything now works as expected.

MacBook Air M1.

you also need to exec:
echo 'export PATH="$HOME/.jenv/bin:$PATH"' >> ~/.zshrc
The PATH env variable is what you missed.
Source:https://www.jenv.be/

Then enable the export plugin:
jenv enable-plugin export
exec $SHELL -l

I found that if PATH is not set correctly, jenv wouldn't set JAVA_HOME even if the plugin is enabled
