mvnd seems to not respect jenv local setting

[korthout]

I just installed mvnd and noticed it was using a different jdk than mvn.

I installed mvnd using Homebrew. Perhaps I need to configure something additionally.

Any help is appreciated.

Here's the output of some local shell, java and maven info:

$ jenv local

🤦 I need to read README's better.

I found jenv/jenv#324 which refers to the jenv README, which in turn clearly states that JAVA_HOME is not exported by default and the export plugin should be enabled by executing:

jenv enable-plugin export
exec $SHELL -l

Running mvnd now respects the correct jdk set by jenv:

$ mvnd -v

Thanks for the report and solution, @korthout!
