A way to install a JDK from a directory

[dkowis]

This is a bit tougher, but with jenv, I could install a JDK, and do something like jenv add /path/to/jdk and it would determine the major, minor and patch versions from the output of java -version in that directory.

It was really handy to be able to add a JDK, especially the ones from oracle. I'm not sure how this would work, but it'd be useful. Found myself missing this functionality yesterday.

Wouldn't you have the same behaviour if you use the .tool-versions file in the directory you would like to use the desired Java SDK?

[dkowis]

Well, only if the asdf java plugin knew where to find said java SDK. Right?

I'd have to have some way of adding it to the plugin first.

You can symlink the custom jdk to the $ASDF_DIR/installs/java and reshim and it will work fine. Just ln -s {path_to_jdk} "$ASDF_DIR/installs/java/{custom_jdk_name}" and then asdf reshim java

On MacOS make sure you include the /Contents/Home to the path, so for example:

ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_80.jdk/Contents/Home ~/.asdf/installs/java/oracle-1.7.0
asdf reshim java

This will make it possible to do:

asdf local java oracle-1.7.0
asdf which java

/Users/wessel/.asdf/installs/java/oracle-1.7.0/bin/java

java -version

java version "1.7.0_80"
Java(TM) SE Runtime Environment (build 1.7.0_80-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.80-b11, mixed mode)

Hi just noticed (again) this issue,

For reference, here's a use case that might be useful. And if download was handled by asdf-java it would allow to skip the download step.

Here's the verbatim comment from #92:

Hi, just chiming in, currently I'm using specific JDK builds and I'm doing the following. This would be nice if the add a local version could be extended to adding a remote version too.
