I had the same problem, for me the issue turned out to be the file /etc/mavenrc which resets JAVA_HOME back to 1.7:

JAVA_HOME=`/usr/libexec/java_home -v 1.7`

I manually changed it to

JAVA_HOME=`/usr/libexec/java_home -v 1.8`

And that resolved the issue.

I have installed maven with homebrew. I couldn't find /etc/mavenrc. Never the less this solution is not sufficient for my need. I'm using java 8 in most places and one project requires java 7. I wanted jenv to set the proper java dependent on the project. And it is working until new shell is launched. I'll try to debug maven launching script. Maybe there is the answer.

Could you provide output of 'jenv doctor' ?

➜ ~ jenv doctor
[OK] No JAVA_HOME set
[OK] Java binaries in path are jenv shims
[OK] Jenv is correctly loaded

I run rehash and it helped. Now maven picks proper Java. I thought I did executed rehash earlier but maybe I forgot. My mistake.

Checking all possible places of a mavenrc for a sneaky JAVA_HOME setter may work. You need not change it, can also remove it cause jenv export plugin can set JAVA_HOME for you.

After rebooting of my mac the problem is showing again. Running jenv rehash solves it until next reboot.

Could you give me output of
command -v mvn ?

Update: Nevermind. I missed one mavenrc that defined java home...

I seem to have the same problem. I'm trying to set a local java for maven to use, but am unable to do so.

Any ideas?

I had the same problem and found a workaround by setting JAVA_HOME in ~/.mavenrc like this

JAVA_HOME=$(/usr/libexec/java_home -v $(jenv version-name))

$ pwd
/tmp/test-1.8
$ jenv local
1.8

@gaetanlebrun after much googling and reading stack overflow/github whatnot. I could fix my maven / jdk issues with your suggestion. Thanks.

However, I did want to search further and noticed that /etc/mavenrc also did some overriding. Getting rid of that actually made jenv and mvn play nicely. Without the JAVA_HOME path setting by @gaetanlebrun .

However, when trying gradle I actually ran into this problem again and the JAVA_HOME fix also fixed that. The most ideal scenario would be to not set it like this, although not setting a JAVA_HOME at all feels quirky.

@gaetanlebrun : Instead, I removed JAVA_HOME from ~/.mavenrc and everything is working fine.
Thanks for pointing that file 👍

I had this error after updating jenv. I ran the following 2 commands to get everything happy.
jenv disable-plugin export && jenv enable-plugin export
jenv disable-plugin maven && jenv enable-plugin maven

I have the same problem after updating.
After looking into the files inside ${userhome}/.jenv/shims/.
The exec command is pointing to the old version of jenv in my case it was 0.5.2 instead of 0.5.3

I didn't have any time to deal with it so I remove the folder and install fresh jenv from brew.

And of course adding manually all java installations.

Home brew version: 2.3.0

I had this error after updating jenv. I ran the following 2 commands to get everything happy. jenv disable-plugin export && jenv enable-plugin export jenv disable-plugin maven && jenv enable-plugin maven

Thank you @smgardner59, that did it for me... weird
