Adding 2 java versions to jenv and I end up with a long list of verisons?

[iangregsondev]

Hi,

I did the jenv add for

and now i get 8 different versions, I was expecting 2. What am I doing wrong. It seems for example doing the following line actually adds 2 entries.. i.e. this line

jenv add /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home/

actually lists under the jenv versions 2 entries.

1.7
1.7.0.80

This is now my complete list.

➜ ~ jenv versions
system
1.7
1.7.0.80

• 1.8 (set by /Users/ian/.jenv/version)
  1.8.0.45
  1.8.0.74
  oracle64-1.7.0.80
  oracle64-1.8.0.45
  oracle64-1.8.0.74

Same here, I just installed java with cask, jenv with brew, and this is what I got:

$ jenv add /Library/Java/JavaVirtualMachines/jdk1.8.0_77.jdk/Contents/Home/
oracle64-1.8.0.77 added
1.8.0.77 added
1.8 added

That is the expected behavior.

That is allow to select any major version if needed ( 1.6) or à very specific one

Ah Ok, got it. Thanks. This does make sense now.

So just out of interest. If I install, for example 1.8.0_73 and _77...

so 1.8 would point to the last one added ? or the LATEST ?

Mine shows this, and what is confusing about it is that these 2 links that start with "oracle64-" are generated and I don't know where those come from:

r0000@t0000 ~/.jenv/versions $ ls -a ~/.jenv/versions
./  ../  1.7@  1.7.0.80@  1.8.0.92@  oracle64-1.7.0.80@  oracle64-1.8.0.92@
r0000@t0000 ~/.jenv/versions $ jenv versions
  system
  1.7
* 1.7.0.80 (set by /Users/r0000/.jenv/version)
  1.8
  1.8.0.92
  oracle64-1.7.0.80
  oracle64-1.8.0.92

I never added those to oracle items. Now, if these are auto-generated, it would be nice if the command would say so, for example, like this:

r0000@t0000 ~/.jenv/versions $ jenv versions
  system (auto-generated)
  1.7 (auto-generated)
* 1.7.0.80 (set by /Users/r0000/.jenv/version)
  1.8 (auto-generated)
  1.8.0.92
  oracle64-1.7.0.80 (auto-generated)
  oracle64-1.8.0.92 (auto-generated)

The way it is now, its a little confusing and the first thing I thought was WTF.

Same confusion with

$ brew cask install java7
$ jenv add /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home
oracle64-1.7.0.80 added
1.7.0.80 added
1.7 added

So, oracle is auto-generated? What does that mean?

[bunnyhero]

i find if i try to use the "oracle64-*" ones, i get an error like this:

Unable to locate an executable at "/Users/bunnyhero/.jenv/versions/oracle64-1.7.0.45/bin/java" (-1)

but 1.7, etc, work fine.

@gcuisinier Hi, so what about this oracle-* prefix? What is the purpose of it?

[LIttleAncientForestKami]

One additional note on why it's confusing as it currently is:

./jenv add ~/.sdkman/candidates/java/8u152-zulu/
There is already a openjdk64-1.8.0.152 JDK managed by jenv
Do you want to override (type y to confirm)? y
openjdk64-1.8.0.152 added
There is already a 1.8.0.152 JDK managed by jenv
Do you want to override (type y to confirm)? Y
1.8.0.152 added
There is already a 1.8 JDK managed by jenv
Do you want to override (type y to confirm)? y
1.8 added

Out of one op I have three. Also, first my thought was: oh, it repeated the question, so it didn't override it previously? Or is it that 'y' doesn't work? Let's try 'Y' then!

Of course, that may be just me. Still, while I like the idea (choose Oracle or Zulu, choose 7 or 8, don't bother with smallish numbers), I think it should be more like an aside.

$ jenv add someJavaVersionFromSomeProvider
full-version-string-with-X-provider-and-Y-major-version-number added
Provider X set to full-version-string...
Major version Y set to full-version-string...

Same with overriding. My 2 cents obviously. I'm open for why you want it your way, may well be better.
