Shims not updated after upgrading

[udalrich]

I recently did a brew upgrade, which updated jenv from 0.5.2 to 0.5.6. This caused most of my java-related command to fail with

/Users/me/.jenv/shims/java: line 21: /usr/local/Cellar/jenv/0.5.2/libexec/libexec/jenv: No such file or directory

Based on jenv help, it appeared that jenv rehash might be what I wanted to do, but that also failed:

$ jenv --version
jenv 0.5.6
$ jenv rehash
jenv: cannot rehash: /Users/me/.jenv/shims/.jenv-shim exists

At this point, I renamed .jenv-shim to see if that would fix the problem. jenv rehash did not report an error, and java --version and mvn install (with the maven plugin installed) seem to work now.

So I think I resolved the problem, but it required moving around files that feel like they are internal files that I shouldn't be touching and guessing at what the solution is.

I think at a minimum, jenv rehash needs to be modified to work when the shim file from an older version is present.

If there is a brew post-install hook that you control, running (the fixed) jenv rehash from that would also be a good idea. I am not familiar with the details of how brew installs things, so I have no idea how reasonable the post-install hook is.

Got the exact same issue.

I had the same issue and this resolved it. Thank you so much!!

Thank you for documenting both the problem and the solution... a post install hook to rebuild the hash would be very helpful.
